Little one @ Blvd

Date: August 18th 2012, Saturday
Observation Time: 7:30pm to 11pm (observing time ~3.5hrs), 
Location: Jon's @ Blvd
Weather: fine.. 4/5 seeing.. before sunset it was cloudy, but later clouds just disappeared. Moon - 1st day 
Instruments: Jon's 16" scope and his Williams 80mm scope  


Our little one visited Jon's place in mountains for first time. Slept all the way during the drive. But played for a while at their place. Later got into daycare anxiety mode and just made everybody go nuts..later got back to normal.

Moon: FAILED. Started observation with locating first day phase moon. But it was way too hard. Never found it. It was Ramadan Ed 1st day moon.

Saturn: Saturn-Mars-Spica triplet as visible in evening dusk. Saturn visible nicely. Tried thru Williams 80mm with 9mm, 4mm TMB eyepieces. Saturn rings clearly visible, front rings are on bottom, while the back side f the ring moves upwards. As night moved on, can clearly see the dark gas lanes on the saturn disk. No details / gaps on rings. Still it was impressive what 80mm scope showed from the dark place.

Mars: 80mm is not enough for mars details. Seemed like big orange bright spot in the scope. Going closer to horizon, so dint get a chance to see thru 16" scope.

M6-M7: naked eye visibility. Fits in same view in the binocs ~6deg FoV. Jons 16" scope lot of details on both. Butterfly shape. apparently i got this pair confused with m46-m47 and ended up looking for the planetary nebula in it. Jon reminded me of absence of last year. Hsshh..

Antares GC M4: Visible thru bincs. 800mm with 24mm EP, shows the GC nicely. Very tiny though. With 9mm, i think can resolve some outskirt stars. 

Northern Jewel Box: Looks nice from all three instruments. Binocs show 5-7 stars low on horizon. 80mm has the best view. Cluster fills up 50% of the view. bright stars with some E + 4 + curved shape visible. In Jons 16", view was fully filled with eyepiece. Can see very faint stars. 

M8 - M20: Quick browse thru. Lagoon without filter still shows lot of nebulosity and C shaped dark lane separation clealt from 16" scope. Triffid looks smaller as compared to Lagoon, but whole nebulosity is nice. More I spent time in EP for Triffid, the dark lanes started popping up.

Swan M17: Quick browse again.. but impressive.. distinctive shape and bright stars at the bottom and another one at the center  in the curvature shape. 

Eagle M16: no nebulosity... typical star formation like a symbol of an angle.

M22 GC above star: quick browse thru binocs and 80mm.. is it bigger than Antares GC 

M25 OC Flipped comma: Binocs show the 3 deg view of this object with inverted comma shape. OC at the center of the comma is smaller, but the whole spae makes it beautiful. 

M23: While looking for Crescent nebula ended up on this one. very bright and impressive object. 16" scope view is just lightend bright with this object. lot of yellow white stars. 

Crescent Nebula: Very tiny fuzzy object from the 16" scope.. but its definitely bigger than other planetary nebula objects like saturn nebula or ghost of jupiter. Can not miss the object frm 16" scope.. next to a star. Infact i found this one first rather than way bigger M23 :). Increasing the mags didn't make much difference though in the visibility... There is a GC nearby it.. i think you can definitely distinguish betn the type of these objects i.e. GC vs nebula.

M10-M12: Browsed the Ophiuchus GCs. Very impressive. looks similar in size as well brightness..somehow binocs gave impression that m12 is bigger, but scope shows m10 t be bigger. Hshh.. must be feeling sleepy. Very easy to locate. Probably saw these after a long time. no discernible shape.. but these are definitively bigger than m92 in Hercules (later).

Planetary ngc 6445 Box Nebula (New): Jon showed this planetary. seemed like bright blue circle...very very tiny.. dont remember anything else. Later i was able to locate it smoothly. There is another GC next to it ngc 6440. In moderate view the pair looks nice.. very tiny and faint..probably only possible in high apperture 16" scope

Ngc oc - Ic oc - Ic oc: NGC is definitively looks nice from the16" scope.. but IC objects are better in binocs. ngc-ic and the planetory fits in same view. 

Gc near spica: Jon showed this one. wasnt able to locate it by myself. its seemed like OC, but its loosely connected GC.

M13: Took a long time just to locate HER constellation. I sort of lost the scale of quadrilateral size. It is smaller than what I was thinking. One year gap in observation made me forget lot of things. M13 is fabulous.. supports magnification really well. yellow white stars.. very bright.. 

Gal: Gal near M13.. very faint and tiny as compared the M13. Wasnt able t fit both in the same view of 16" scope.

Planetary: Again.. yet another planetary..

M92: Tiny as compared to M13.. but i compared it immediately with m10-12 pair.. and m92 seems smaller and fainter than those.. Its sort of lost beauty in front of other fabulous GCs in the sky.

Saturn Neb: Easy to locate. White bluish object.. tiny.. 

M Gc.. M oc: browsing all three objects including saturn neb, is an interesting experience. It shows the differences in the object size. The triagnle is so tiny.. OC is very tiny as well.

M30: Viewed thru binocs.. very tiny.. the typical shape sort of shows up but not discernible well from binocs.

Milkyway: the orion and Perseus arms were marvelous.. its like very bright white cloud belt in the sky.. Dark skies rules... simply breathtaking.

Being Obsessive.. Part II

Continued..

Draco
========
M102 spindle and galaxy 5907 next to it : M102 was my missing messier and we found it this time. While looking for it, we ended up 5907. Just based on Telerad location, it didn't seem like the right one. 5907 is still very impressive. long, edge-on. not that faint. Took us a while to get to M102. M102 is definitely smaller than ngc, but brighter. Its very close to a star, which is barely visible through naked eye.

So if we have been looking through smaller scope, then i believe m102 will pop up first and ngc would be hard to catch. Now thats a big gotchaa in this big scope, everything seems to be relatively brighter and so will get confused often.

Finally.. I have bagged all messiers now. Still need to observe these more than once.

Gemini
=======
Eskimo Nebula: When I asked Jon, what was the most interesting object for him in his new big aperture scope, he had mentioned to me about Eskimo nebula. so visited it tonight again. Jon located this one. At 400x, very bright circular disk. Core is brighter. Inside the circular disk and outside the core, you will see some inner ring. With more magnification of 522x in 7mm Nagler, the inner ring was clearly visible. Seeing wasn't so great, so had lil hard time to get the sharp view. Jon observed it at 760x as well with 4.8 Nagler.

Taurus
=======
M1 : Crab nebula : Very big, bright elliptical fuzzy. no internal details visible. but definitely one of the bigger objects in messier list.

Leo
====
M65-M66-3628 triplet : Indeed beautiful and bight triplet. Fainter 3628 was edge-on. probably brightness is same as Draco 5807 gal and similar in size.

Bootes
======
M3 GC : Looks nice in the big scope. Stars can be resolved at the core. Stars really weren't pinpoint because of seeing (i guess).

Virgo
======
Markarains Chain : Browsed through Markarains chain and near by fuzzies. Probabaly observed in following order: 1 (4429) + 1 (4440) + Markarains chain {{ 4 (M86+M84)-+ 2 + 2 + 1 + 1 + 2 }} + 1 (M88) + 1 (M91)

Also, while relocating, observed few more : M58 + 4564 + antenna galaxy type pair (4567-68) + some more fuzzies that i don't remember now :). The fainter galaxies also seem brighter in the big scope, So really need to watch out.

Browsing through this region gives idea about all types of galaxies : brightness, size and shape.

Saturn
=======
Visited twice during the session. Seeing was always bad. Rings were bright. Saw a darker band on the Saturn's surface. According to Jon, it should be the shadow of the rings on front side. this dark band-shadow was aligned with back side of the ring. Ashwin got confused, wondering how we can see the rear part of rings like this. Instead it was the shadow of front part of the rings. Wish the view would have been more sharp. It was the last object of the night.

Summer Kickoff - I

Date: July 4th, 2010 Sunday
Observation Time: 8pm to 1pm (5hrs),
Location: Jon's Home, Boulevard, CA
Weather: Excellent.. no clouds.. lil wind in the beginning, but later calm.. so seeing improved..
Instruments: Jon's 16" dob, my 10" dob, NP101 APO.
Buddies: Jon

Venus - Observed thru APO. Image seemed blurrier.. also lot of green/violet color, considering APO :-). Thru 10" dob, good image. looked like a small scale moon. Venus phase of ~60% lit clearly visible. Thru 16" better image of the same. no surface details visible.. its all white..

Saturn: Rings clearly visible thru 16". Thru 10" dob @ 35x (Pan35mm) the rings are visible.. image is too tiny @ 35x, but can distinguish the rings clearly.. when looked thru eyepiece, can see the light distortion i.e. "seagull".. collimation may be lil off. but by changing the viewing angle, the distortion was going away. Two moons on one side. 171x

M57 Ring Nebula: Visited multiple times. In the twilight and APO, seemed really fainter in APO. no star visible at 2". seemed all gray color. Later in the night thru 10" dob nag17 @ 71x image seems sharp and quite bright.. the star at 2" is visible. bluish color visible. Compared with uhc and then oiii filter. image seems definitely brighter thru filters. Need to try high mag filtered image.

Browsed the whole sky naked eye to get a feel of it.

Omega centauri: Lower on horizon, visible. In twilight, not that sharp. Visible thru bino.

M80: In Scorpio. Jon reminded the location. Above the Antares and twice the distance from Antares-lower star. In 10" dob 17nag 71x seems fuzzier, not clear.. ~171x still non-clear watery image. Visited it later at 11pm and the image seemed clear and sharp. In Jon's scope outer stars well resolved.

Ophiuchus PN NGC 6572: Blue Racquetball: Bright, sharp. In 71x Nag17 it seems like brighter blue star. Hard to differentiate it as the PN. Note the triangle pattern of the PN with other two bright stars. Increasing the mags @ 171x makes it brighter.. but still no details visible on the PN. Addition of OIII filter clearly makes it brighter. Visited multiple times.

Oph OC NGC 6633 and IC 4756: Looked at the OC NGC and IC.. NGC seems to be yet another OC, but IC cluster seems to be impressive.. IC bigger than ngc. In 71x it fills up whole eyepiece.. ~30 stars.. all yellow.. evenly distributed.. Switched to lower mag to get the feel of it. In Pan 35, 35x it seems more beautiful.. can clearly see the cluster at the center. seemed like wide salt-pepper cluster.

Blue Flash nebula NGC 6905: In Delphinus. At 71x itself, lil hard to differentiate than background stars. visited it before 1.5 years back, but forgot the location. 85deg (~90) angle on Delph diamond + bright star and this Neb. Note the 3 stars in straight line alignment. also a bright pair nearby. At 71x, seemed faint circular shape.. seems bigger than previous PN, racquetball, but fainter.. no color visible. At 171x, the circular shape clearly visible. Can not see much pattern on the disk. no color visible. OIII filter helps... but i felt that, for searching this neb, UHC filter really helps, as the neb is definitely visible with background stars. More mag helps.

M71 GC: In Sagitta. In Pan 35, 35x looks impressive.. lil bigger than M80, but defintely smaller than M4. clear, sharp.. and outskirt stars lil resolvable. Didn't try high mags.

M27 Dumbbell: Closer to M71. Compared all above tiny PNs, way bigger and so much nebulous. Tried 71x and 171x.. don't see any colors in it. With OIII filter, brighter.. Can see lil dark spot within the nebula.

Veil nebula - 10" @ 35x No filter. Cyg 52 star, West veil part, witch nebula visible. But can't see the visiblity clearly. Tried to look for eastern veil, but didn't find it. Later visited it again. Tried it with UHC filter. Can see all 3 parts of Veil. West+East+Pickering triangle. Nebulosity visible with background stars. with OIII filter, it just looks marvelous. all background stars are gone. And nebulosty pops up in the OIII filter. Tried the same with APO. Compared UHC/OIII/No-filter in APO on Veil.

Browsed thru Sagittarius Nebulae with UHC/OIII/No-Filter in 10" dob with 17T4 Nag @ 71x.

M8 Lagoon: Without filter it shows the lagoon dark arc clearly. With OIII/UHC filters on, it shows lot of nebulosity filess the 25-30% of EP center. shows the bright part at the center of the nebula. this must be the hour-glass nebula.. need to magnify and have to try it from Jon's 16" scope. M21 cluster nearby.

M20 Triffid: Barely shows the upper Y dark lanes without filter.. shows the cluster on the right. With filter on, it shows more nebulosity near the cluster also. The dark lanes seemed darker.

M23 open cluster above lagoon-triffid line: Visible in the 8x20 finder. Seemed to be yet another OC.

Fuzzies Everywhere - I

Date: May 15th 2010 Saturday
Observation Time: 8:00pm to 12:30pm (4.5hrs),
Location: Jon's Home, Boulevard, CA
Weather: Excellent.. no clouds.. no winds.. probably best night till now in 2010. seeing was lil bad 8/10.. transparency 9/10
Instruments: Jon's 16" dob, my 10" dob, np101 APO.
Buddies: Jon


Venus - telescope not cooled down yet.. pretty bad view from my 10" or jon's 16" scope.. blurry..

Moon - few degrees west from venus.. second day phase of moon.. really slick.. excellent view of venus-moon pair as the darkness evolved.

Saturn - excellent view from 16".. jon's scope more stable than mine.. ring, shadow of the ring.. lil gaseous pattern on the disk, 3 moons on right.. in my 10" scope, 7mm image was good.. but barlowed 7mm really blurry..

Castor - easy split with my scope. 4.7 arcmins is indeed easy to split.

Izar - Indeed interesting. companion is in a diffraction ring of primary star. from APO NP101, its a marvelous view. with my 10" scope, can see it, but not as sharp and clean as the apo.

Gamma Leo - Easy split. Companion seems smaller than Primary.

Porrima - Indeed hard.. higher magnification thru Join's 16".. don't remember how much. Its not an easy split. I am able to manage it with my scope. with 7mm ep i.e. 171x (i guess)

M44 - Beehive thru my 10" 35mm pan @ 35x.. looks marvelous. Are there any doubles in here???

M3 - Lost a track to locate this one. Not sure why it happens. Excellent view. Darker the sky better view..

-- Hot chocolate break --

Virgo All messiers: After last week's vrgo browsing, I have gained some confidence in how to browse through fuzzies in this area. In fact last time i missed few nearby messiers.. with smaller 10" scope + 35 Pan @ 35x, shows whole area clearly. should observe this when it real dark and calm, to see more fuzzies at such a low magnification. I was expecting lil better view in my scope, probably lower mag didn't show much. Still can clearly see lot of messiers and ngc objects too in markarains chain.

6 Com star-M98-M99-M100-Markarains chain with M84-M86-4388-4387-4402-Eyes4438-4435-4461-4473. Also M88 and M91 were clearly visible because of low mags. I missed these two las time. Again, M87-M89-M90 visible. On eastern side, M58-M59-M60 were also visible. Lil down M49 was an easy catch. I also mentioned to Jon abt missing M61 (New).. both of us located it and looked at it together. Easier to locate.. Jon noticed few NGCs nearby too..

Did I miss M85, which lil above M100 ??? Hmmm...

Continued..

Dark night kickoff in freezing cold - III

Continued..

Ant galaxies: Too faint.. can see two fuzzy lil things.. but cannot discern much. Tried it multiple times during the night, but wasn't much clear.

Saturn: Multiple views. Seeing was improving over the period, ring shadow is visible. 3 of the moons on right side visible.

Virgo Markarain's chain: 3 in the middle. Two on the right of it. one more on right of the pair.

Jon mentioned about coma borealis - second star - double - 0.7 arcsecond... can not split it with normal optical scope. needs excellent seeing. the day before jon was able to split 1.3 arcsecond double.. so surely this is not even possible in best seeing.

Co-hosting 22" SDAA Observatory. II

Date: April 18th 2009, Saturday
Observation Time: 7:00pm to 2:00pm (7 hrs)
Location: TDS, CA
Weather: Weather is okay.. Transparency is good, but seeing is not good..
Instruments: SDAA Lipp Observatory 22" RC, f/7 (FL: ~4000mm),
Nagler 31T2 EP, 20T5 EP
31T2 => 129x
20T5 => 200x
Buddies: Jim and public.

Volunteered to co-host SDAA public star party with the observatory scope. First time, handled such a huge scope, on EQ fork mount. In the beginning had hard time due to huge mount, new type of mount, poor alignment and awkward finder. But After few hours got confotable with telerad-31T2 EP and normal star-hopping..

7pm: Some admin stuff to open observatory. Tried to align on Sirius. Didn't collimate (??)

M46 OC: Pretty nice. pinpoint stars. bright.. PN was also bright, blue in color. The middle star is visible and bright. not sure if the star is part of cluster or PN.

Orion 73 cluster (New): OC in orion, with asterism in shape of 73, but each digit inverted L-R.

Saturn: Bright. 4 moons visible. titan + 1 on left and other two on right. Other two were really close. rings and shadow of ring visible. higher mags didn't help. seeing was bad .. visited saturn 3-4 times throughout the night, but seeing never improved.

M97 Owl: Failed. digital setting circles not setup correctly.. too frustrating..

M81-82: Initially Failed. I was replying again on encoders. After few attempts, somebody (Pete) helped to point it. Can not fit both in same view.. was worried to move it because i may loose it again :).. The mottling on M81 clearly visible.. also vertical dark lane was visible. M82 was bright, but no details.

M51 whirlpool: Jim pointed to this one.. Spiral structure clearly visible. Bright spots inside M51 visible clearly. Probably thats what i saw other night with Jon. People were saying with averted vision connection betn both galaxies visible.

4965 Gal in Coma (New): Marvelous. Way better than M104, How the hell Messier missed it.. Huge, filled up complete eyepiece view. bigger than m104, edge-on, dust lane clearly visible and its thick.. core wasn't that bright.. the object was so impressive that i wasn;t sure if its really the object or the scope.. whatever.. unforgettable view.

M84 + Markarains Chain: all galaxies were huge..and chain clearly visible.. again lil skeptical of moving the scope, but shows so many galaxies in the view.. clearly 5 visible in the same view. Tried to realign encoders. Revisited again at the end of the session. See details below..

For re-alignment, moved to Arcturus. just too bright in this scope. Because of the brightness, hard to see where is the center of the view, so not a good star for realignment. Tried M51 again after realignment. DEC encoder is setup correctly, but RA is still off. but with DEC inline still helps to get the object in view, by moving thru RA.

A recticle-crosshair eyepiece is better/perfect way to get object in center. also whats the point in aligning on a DSO, considering its size ??

Eskimo nebula in Gem (New): Jim pointed to this one. Marvelous view. perfect round shape. outer disk is brighter, inner part is darker. no hint of star. probably same size as M57 (??)

After this, the scope was solely operated by me. Decided to just starhop with telerad. Perfect star hopping and very little help from the encoders. Overall reminded me how helpful it is to observe with Jon.

M104 Sombrero: Really nice view. better than Jon's 16.5" scope. magnification also adds up. still smaller than 4965 Coma galaxy.

M13 GC: Wow.. masterpiece.. All outskirt stars resolved. also, few stars at the core resolved. 20T5 EP also helps. Jim tried meade 14mm UWA, but stars weren't pinpoint.. both seeing as well as "meade-vs-nagler" to blame.

M92 GC: sort of naked eye. This one looks like "M13 in my 10" scope" :).. looks amazingly impressive. Almost all stars outskirts resolved and few at the core. This 22" scope makes every object beautiful :)

PN in Hercules: Easy Starhop after yesterday's session with Jon. Bright blue color disk.

Gal next to M13 (New): Yesterday Jon showed me this one, and today while pointing towards M13, I saw this. Tiny little fuzzy.

M65-M66-3628:

Corvus PN: Looks like a galaxy rather than PN. no bluish color, so easy to confuse with galaxy. bright star at the enter.. just too bright, looks like tiny core of the galaxy. Never seen like this before.

Corvus Antenna Galaxies: Awesome view. both galaxies clearly visible, but antennas not visible.. seeing matters. Still "merging" of two galaxies clearly visible.

Ghost of Jupiter: bright bluish disk. both disk and inside ring visible. middle star clearly visible. 20mm same image.. tried 14mm meade UWA EP, but extension tube trouble. wanted to try filter also, but skipped it.

M83 seashell: Easy catch. Huge object.Observed it yesterday for first time and already star-hopped to it today :). Bright core..

Omega Centauri GC: Little low on horizon. Ladder requirement. almost resolves every star. fills up ~40% of 31T2.

Centaurus A Gal (New): Easy catch. Perfect starhop (??). Was lil skeptical to observe something new on this huge scope without finder, but starhop was easy to catch this one. Bright, the middle dark lane is huge.. its like 3 or 4 times the size of 4965 galxy dust lane. Its perfect "hamburger" shape. both sides (buns) are bright. but consdering the size of dust lane, whole galaxy is not that huge. Need to read more abt this one (??)

Leo 2903 Gal: Perfect Edge-on easy catch. Don't remember much.

Leo Gama Gal doublets: Gamma was hard to split in 129x. surprising. bad seeing? Galaxies visible nicely. Again too small as comapred to any other galaxies i saw tonight. also i am impressed that my 10" scope shows this one clearly.

Leo 3521 Gal (New): Lil bit difficult star hop. Info says "spiral galaxy", but hard to see clearly.. surely face on.. probably same size as antenna galaxies.

M57 Ring Nebula: Apperture helps. huge ring. blue color discernible. middle star not visible..surprised..

M53: Failed: Picked up wrong Alpha coma star, also somehow encoders pointed it somewhere else..

Coma/Virgo Galactic cluster: spent more than 30mins in Coma and upper Virgo galactic cluster.
M98-M99
Markarains Chain with M88-M91
4371
M87--4478
M89

Overall, though started lil slow and with nervousness, finished with complete enthusiasm. till 2am I was going on-and-on without any food :)..

Marvelous experience because of:
- Able to handle such a Huge scope first time
- Handling new type EQ fork mount compared to my dob mount.
- Every object looks beautiful in this aperture. Was completely overwhelmed.
- Survived smoothly at the end, though started under huge peer pressure :)

Friday KC Dark Night - I

Date: April 17th 2009, Friday
Observation Time: 7:00pm to 1:30pm (6:30 hrs)
Location: KC, CA
Weather: Weather is okay.. Transparency is good, but seeing is not good.. lil bit wind and it increased every now and then.. wind was pretty bad at 10pm as well as 1:30am.
Instruments: Orion XTi 10, Jon's 16.5' and Jon's 15mm, 24mm TV widefield EPs and WO 28mm UWAN EP.
Buddies: Jon

New Objects: 12 + Markarins chain

Rigel (New): Nice Double. wasn't aware that its double.. don't remember details..

Gamma Leonis: Yellowish pair.. easy split.

Saturn: Seeing is okay.. not great image.. surpringly for whole night, never visited it again.. seeing was also bad..

M36: Comet Cardinal (New): M36 Y cluster. Tried to locate Cardinal just next to it.. but i guess it wasn't dark enough so didn't find it.

Lambda Orionis: Mriga Shirsha: Multiple stars, but one of them is double..

M79 in Lupus: Again not dark enough, so took a while to find this GC. Preety low on horizon. Faint fuzziness visible, hard to resolve any stars at high mag also.

Beta Monoceris (New): Impressive Triplet. all white. With 38x, only a pair, wide enough.. but at higher mag 76x, you can see one of the star itself is a double and preety tight.

Castor: Bright castor with really faint red companion. Really wide double, easy to split in 38x also.

Gemini Planetary Double: Jon showed it to me last time and locating this one failed from MTRP. Found it with help of Jon again and confirmed the location.. barely visible in 38x..

Comet Lulin: Visible in Jon's 16.5" scope... really faint, but still visible.. mag 11.. Tried comet Cardinal again.. failed..

M35: Impressive Cluster. You can see the bright curved line inside the cluster. NGC was on the SW of the cluster. Wanted to confirm the NGC w.r.t the curve line.. Its in the same line as the curved line inside M35.. but located way outside M35. should be able to find NGC from MTRP.. but its indeed faint. At the other end of the curved line, there seems ot be a double star.

Also tried Jon's TV 15mm Wide Field eyepiece (80x). It definitely has higher FOV than my 32mm x 2x barlow.. It fits whole M35 as well as part of NGC.. but mine doesn't fit both at all. the eyepiece is defintely better than mine, but eye relief seemed to be lil bit low. Need to read more abt this eyepiece specs (??)

Tau CMa: Along with Jon's 15mm TV, tried 24mm TV wide field. Again 24mm, has better FOV than my 25mm Elux, but as far as performance concerned, my 25mm gives good image too.. wasn't able to differentiate them..

but overall, 15mm TV eyepiece was better than 24mm TV.

MTRP - Calle De Vida

Date: Apr 12th 2009, Sunday
Observation Time: 8pm to 9:45pm (1:45 hrs)
Location: MTRP, CA
Weather: Okay.. Seeing 4 of 5. Transparency 3 of 5.
Instruments: XTi 10.

MTRP Clairemont Mesa entrance is closed now. So entered thru another entrance Calle De Vida, 2 blocks from original entrance.

Alcor-Mizar: Started with double. At 38x itself, clean split of all MizarA-B. All three white in color. Had hard time determining position angle.

Gamma Leonois: At 38x hard to split, 76x was hinting of a split, but 120x was better... really close.. Yellowish pair.

Regulus: document says its double, but is it? there is a faint star in the vicinty, seems to be optical double.

Orion M42: Okay.. Disk visible. M43 was sort of fuzzy. Trapezium E-F not resolvable at all.

Flame nebula: Failed. Just no nebulosity at all..

M78: Location was perfect, as mentioned from last observation. barely visible though.. faint.

Castor (New): Really close double. 120x is the first one to split.. really close.. higher mags help.. again white pair..

Gem Double Planetary: Jon has shown me thos one multiple times, but i didn't know precise location neither how it looks in finder. Atleast at 38x really hard to see anything. Its one of those objects that need higher mags and precise location. FAILED.

M35 OC: Impressive... The curved line inside the cluster.. didn;t find the NGC OC just otside it. Need to remember the relative position of it wrt the curved line.

Pollux (New): Not a double, but nice yellow-orangish star. Nice contrast betn Castor and Pollux.

M65-66 Triplet: Really too faint. Found it easily. but M65 and M66 were visible. NGC was sort of averted vision, giving a hint of it.. but wasn't sure.. Overall the M65-66 pair was so faint that wasn't worth increasing the magnification.

M81-82: thought that had it in the view, but didn't.. just too faint to see anything.. Last time, caught it without any trouble, but this time had hell lot of trouble in star hopping. nedd to learn abt background stars. Dark night makes thing simpler :)

Saturn: Spent lot of time on this one. Tested Jon's planetary eyepieces TMB 4mm and 6mm on this one. Went all the way to 2mm using barlow. Somehow seeing/scope was stable. Saturn was marvelous, in-and-out focus, in 3mm (400x) itself and I had breathtaking view. Surprisingly with 600x, it wasn't sharp at all, but still disk was huge and gap between disk & rings was clearly visible.

M3 GC: Naked eye Star hopping session required. hopefully next time i will remember it. Finder shows it clearly. At 38x its fuzzy, At 76x Outskirts is resolvable. At110x few star in front of the core are resolvable. 200x didn't make much difference.

M53 GC: Easy. Next to Aplha-Com. Finder barely sees it. 38x, 76x shows it as fuzzy, but 110x resolves couple of bright stars at outskirts.

CMa & Hydra browsing..

Date: Apr 1st 2009, Wednesday
Observation Time: 8:30pm to 10pm (1.5 hrs)
Location: SD home, CA
Weather: Excellent.. Seeing 4 of 5.
Instruments: New Orion XTi 10.

M41 OC: Wasn't impressive at all.. Red hue in background from light pollution..

Tau CMA OC NGC-2362: Easy catch. Not as impressive as seen from dark location KC, but still easily identifiable at 30x (42mm). Higher the mag, more stars are resolvable. with 110x-10mm, can get around 35 stars. Sort of traingle shape of the cluster.

NGC-2354 (New): 3 stars in triangle. really tiny.. TBD (??).. FAILED. Wrong observation.

NGC-2359 Thors Helmet (Failed): Can not watch this one from home at all. Jon had told me that, but still attempted. Star-hopping was fun. I think the locaiton i was pointing was correct, but no nebulosity visible. To look for Thor's, Browsing thru M46-47 line wasn't that useful, but Browsing from Sirius-Iota-Gamma then to NGC-2360 & NGC-2374 OC is better hop. 30x-42mm really helps in star-hop.

NGC-2467 & M93 (Failed): 30x-42mm helps again in star hopping. M93 is easy. NGC-2467 Failed. the starhop seems straightforward from Xi to Omi pupis, but no nebulosity..

Saturn : Best ever view from 10". At 220x, marvelous view. Crispy clear image. It ws one of those views, where you feel like having more magnification. 3 moons on west side, while one on east side. rings were fabulous. The slanted-top view of rings visible. Gap between rings and saturn was poping in the eye. Shadow of rings on disk, below the rings.. like a dark band. Northern and Southern equatorial band clearly visible.. above that towards polar side everything was sort of white. The image indeed was sharply focused and gave perfect 3D feeling.

Wasn;t sure what to observe. so picked up Hydra for first time. Bno browsing was indeed helpful to identify what is visible from patio.

NGC-3242 PN Ghost of Jupiter (New): Star-hopping from east side Nu-Phi Hydra is easier than going thru Alpha-Hydra. Really easy star-hopping. Lil hard to see the ghost in 30x, 42mm.. can be missed..but 32mm, 38x indeed shows the fuzziness..atleast can see the difference betn star and fuzziness..higher mag helps. At 110x, feels blue color. At 220x, the PN size is half saturn disk. 220x indeed shows a ring rather than blue disk. So central part is light in color, the middle part is bright blue colored ring, while outskirts is again light colored.. Averted look, helps to feel the brightness of the blue ring. this will be fun to watch from dark place. TBD (??)

Messier Marathon - Part II

Continued..

NGC 2467 nebula (New): while looking for M93, ended up at this one. M93 is on one side of Xi pup, while this is exactly opposite side, same distance. good looking.

M93, M50 and M48 OC: From Light polluted skies, these guys are prominent, but from dark skies, not impressive. :)..

Overall, during whole night star hopping, while looking for intended objects, I saw so many fuzzies on the way that its hard to keep track. I tried my best to look into star atlas, before moving on.

Also M93/M103 examples show that my sense of direction within inverted image of reflector still messes up sometimes. Have to get a better judgement.

Comet Lulin: In Gemini. In 16.5'. Around mag 9. Fuzziness is still visible easily, but small.

Gemini Double Planetory (New): In 16.5', Marvellous pair of planetory. sort of 8 shape visible. Magnification helps. Don't know the location (TBD ??)

M1 Crab: Watched after long time. Easy catch.. Again directional sense in eyepiece messed up. Mag helps.

M36-M38-M37 OC: M36 and 38 are inside, while M37 is outside pentagon. 36 is smaller than its brothers. It has inverted Y shape or stick figure tree shape. M38 is impressive with Pi shape, while M37 is probabaly same size as M38 and it has like ice-cream cone shape, with ice-cream on top :)..

M35 OC: This is another impressive object. At lower mags it fills the eyepiece. All bright stars. The best part is that it is acommpanied by a fuzzy object next to it. It seems to be a nebulous object, but somehow star atlas says its a open cluster. If thats the case, it must be really tight, concentrated and star rich cluster. higher mags seem to be resolving more stars in this one. Need to read more (TBD ??)

M44 OC: Beehive was naked eye.

M67 OC: Star atlas helps to point it betn M44 and Hidra head. It is arched H shape. Left arc of H shape is full of stars. Impressive view.

I am glad i noted my observations on paper during the session. Otherwise i would have got confused between so many OCs.

It marked end of first leg in my marathon. Almost all objects from West side are done. Bit tired by now.. Almost 10:30pm !!

Saturn: Okay seeing/ At 220x, image was fine not that stable. shadow of rings visible clearly on the disk.

M95-M96-M105 plus nearby NGcs: Easy catch. All of them visible. Quick glimpse.

M65-M66-NGC3628: Forgot the location.Took few mins. All them visible. 3628 wasn't clearly visible. Quick glimpse.

NGC2903 Galaxy: Read abt this, but never seen it. Easy catch. Well positioned. Almost edge-on.. bright.. Need to spend more time on this..

NGC 3226-3227 Galaxy pair (New): Jon pointed to this one instead of 2903. Its close to Gamma-Leonois. Pair is bright.. (TBD ??)

Planetory Nebula in Corvus (New): Fought for it so much from home, and from dark sight its easy catch. Too faint for home observation, if don't know where it is. Yet another fuzzy, but didn;t look like PN. Pattern visible thru jon's 16.5'

Antenna galaxies (New): Asked Jon to show me this one. Fought for it from home. Too faint in 16.5' also. Hard to see any pattern. Hopeless pair..

Continued..

Late Night Outreach...

Date: 22nd March 2009, Sunday
Observation Time: 11pm to 12pm (1 hr)
Location: SD Home, CA
Weather: Okay.. Seeing was fine. probably 3.5 of 5
Instruments: Orion 10 XTi
Buddies: Ashwin and Alankar

Total Objects: 3
New Objects: 2

Had nice observing session late night, after Imax-Watchmen. Considering the cloudless night, wanted to show "Crispy" Saturn to Ashwin and Alankar.

- Leo
Saturn: Image wasn't sharp, but better than previous observation. Saturn's rings were perfect-edge-on yesterday 21st March. Felt the same. Wasn't able to see the gap betn rings and the planet, so must be edge-on. 3 moons on western side, while 2 moons on eastern side.

- Corvus
Delta Corvi (New): In order to show some variety of objects in the sky, pointed to this double star in "Hasta"-corvus constellation. Didn't try for any mag-separation calculation. Primary is blue-white, while secondary is orange-red in color. Primary seems far brighter than secondary. In 38x secondary was visible, but not clear enough. Heigher mags resolved it better. Secondary position angle is probably 225deg.

http://www.astro.uiuc.edu/~jkaler/sow/algorab.html

- Virgo
To show how galaxy looks like in a scope, I was looking for any nearby bright galaxies. Initial plan was to show Messier galactic zoo in Virgo, but becasue of limited viewing from my patio, skipped Virgo-cluster as well as Leo-cluster.

M104 Sombrero (New): M104 was promising one in the map, but I have never star-hopped to it before, so wasn't much confident.. but BAM...in first shot i got it. Around 110deg angle & ~1.5 times the distance of Delta-Gamma corvi line. In 38x you can see the fuzziness, but barely. Easy to miss this object, but there are 3 bright stars aligned straight to its "SW". Increasing the mags indeed helped in revealing more details. I am surprised with how-much higher mags this object supports in city light pollution also.. At 76x, the edge-on shape was clearly visible. Had a feeling of buldge in the middle, but not clearly. the galaxy itseef is aligned with two other bright stars on west. the edge-on shape probabaly makes 25deg angle with the star-alignment on SW. At 110x, bulge was improved.

Orion CMa Pup "M" browsing

Date: 18th March 2009, Wednesday
Observation Time: 8pm to 10pm (2 hrs)
Location: SD Home, CA
Weather: Okay.. Seeing was okay in the beginning 2.5/5. After an hour it improved. 3.5/5
Instruments: Orion 10 XTi

Total Objects: 11
New Objects: 3

I am surprised how many things I can see from my patio itself. It was good a experience.

- Orion
M42 Orion Nebula: Wanted to investigate Trapezium inside orion nebula. With 40mm (30x), stars C, A, D were visible. B was probably there, but wasn't sure. With 32mm (38x) B popped easily. Additional magnifications 76x, 10mm (120x) didn't help. In-fact 240x was really hard to focus. Probably a bad night.. What is the minimum magnification and seeing required for E & F to show up?

M43: Not a great view. Nebulosity was visible at 32mm-38x, but then lost it at 76x.

Running Man Nebula NGC 1977 (New-Failed): Got the location, north of M43. Saw stars of the nebula. But actual nebulosity was missing at 30x or 38x also. All higher mags were hopeless.

- Canis Major
Started usual browsing of sky and M objects.

M41 OC: Preety sight. With 30x. The E shaped fork was visible. 38x and 76x shows the shape, but doesn't give overall perspective as 30x.

Eta CMa (New): Visual double star. Visible in 38x. Still can not judge the star magnitude and distances properly. Companion is probably 3 times fainter. Also with 10mm-120x, its like 1/8th of the eyepiece view. The distance is probably 3' minutes. ((52 deg/120x)*60)/8)

Info here: http://www.daviddarling.info/encyclopedia/A/Aludra.html

v1 v3 v2 CMa: More double/variable stars in Canis Major. v3 and v2 are only double, as per the map. Saw only v2 to be double. Indeed tight. but still visible in 38x.

- Monoceros
M50 OC: Fainter than I was expecting, still can not miss it at 30x. Twisted and abstract butterfly shape.

- Puppis
M46-M47 OC: Nice pair. At 30x can not keep both in same view.

M47 is made with all bright stars. Closeup look with 38x shows Ophiuchus constellation shape, with small 'k' shape inside.. k or chair shape. All star seems white.

M46 is not as impressive as M47. Lil fainter and sprinkled like M50. No definite shape visible. I missed the PN inside.

This OC pair is marked by two bright star pairs on each side. Indeed impressive.

M93 OC: Really small. initially i missed it at 38x, but found it again at 30x. High mags show twisted A shape. Impressive.

- Hydra
M48 OC (New): Easy catch. Next to hydra C stars. It shows shape of 7, rotated 180deg inside a rectangular boundary.

- Leo
Saturn: Saturn was the only Leo object I was able to view thru my patio. Saturn was impressive. 32mm-38x shows tiny saturn and existence of rings. 2 moons on left clearly visible. The one inside, had uncollimated bright hue aspect to it. Didn't understand what it was, but 76x clarified it. clearly see 3 additional moons, instead of bright hue. First time ever I captured 5 moons of Saturn. 10mm-120x was again impressive. Saturn rings were nice and were giving a feeling of lil bit of tilt, still not sure. N and S gas bands were going in-out of focus. With barlow, 240x was awesome.. Crispy clear view. Seeing must have been improved by now. Gaseous bands on N-S were clear. Lost 5th moon.. wasn't bright enough. rings were indeed showing the tilt without any doubt. Gaps between the Saturn and rings was clearly visible. Cassinni division wasn't visible, i guess because of the low tilt of rings. Still best ever view of Saturn in my 10" scope.

Showed Saturn to Ashwin and Alankar, but by that time, seeing went bad and in few mins fog rolled over.

Comet Lulin

Wed 25th Feb 09, 11:50pm
San Diego Home.
Scope: Orion 10" xti
with Ashwin.

Weather was fine. No clouds. Jut too many lights near house stairs.

Lulin was around 2-3 deg SE from Regulus.

The fuzziness barely visible thru naked eye. Easy catch thru binocs..faint fuzzy.. No green color indication thru binos. In 40mm, Lulin green color visible. No Tail. Its like green globular. not really spherical shape.. but lil elliptical.. bright at the core and fainter & fainter @surrounding.. In 25mm, not a impressive view.. lil blurry. In 9mm, internal coma visible. really bright at the core. Overall, didn't see comet's tail, probabaly being nearby house lights..

Spent some time on Saturn. all eyepiece views were nice.. 9mm was the best. sharp-crispy clear image. rings visible as fine line. Didn't see any gas bands. 4 moons visible. 2 each side.

First Dark Night with Orion XTi 10 - II

Continued..

Horsehead Nebula IC 434: Fought for it.. dark nebula.. star was too bright.. with filter 18mm and without filter on 14mm.. without filter view was better.. but still didn't see Horsehead.. need to identify the precise location.. It seems like we were looking at NGC2024 flame nebula.. we were looking at north.. we should be looking 2-3 deg south..

M1 Crab: In 40mm visible.. 32mm was good.. Know precise location. Supported all higher magnifications.. 25mm - 16mm still good.. lost location in 10mm.. No internal detail visible in higher mags.

Leo Stars: Near Regulus UGC5470 not visible.. i thought i had seen it thru Jon's 10" dob.. verify. caught all stars. Gamma is yellow and has blue companion, but separated by large margin.. Yellow color was impressive.. Watched all stars.. Denebola was too low.

Saturn: looking for Saturn in Leo.. but nothing bright.. got too confused.. but found it next to iota leonoid.. 40mm no rings.. 32mm rings as a line.. but not able to focus.. too low on horizon. verify satellite locations.. two on top (west)..one was really far.. and two below (east).. higher mags didn't help much either.. wavy view.

Leo M95-M96-M105 Triplet galaxies: Star 53 visible averted.. easy catch of galaxies. Saw lot of NGCs nearby in 40mm itself.. M95-M96, M105-NGC3384, NGC3412 (new), NGC3377 (new) next to star 52.. also by using map, located NGC3367 circular galaxy (new), NGC3338 (new). Also, 32mm/25mm mag was best view. It also showed M105-NGC3384-NGC3389. familiar 3 star alignment also.. Brightness M105 > NGC3384 > NGC3389. Large: NGC3389 > NGC3384..

Leo M65-M66-NGC3628 Triplet: Star 73 visible thru averted vision. triplet easy catch.. this triplet much better than m95-m96-m105 triplet. NGC3628 is perfect edge on. Looking at map, found all tiny guys.. NGC3593(new) and NGC3596 (new) next to theta leonoid..

TBD:
- Intelliscope battery
- Observe each object more carefully. M46 is an example of ignorance.
- Observation Plan is necessary
- Too cold out there

First session with Jon Issacs...

Date: 28th June 08, Saturday
Observation Time: 8:30pm to 12:00pm (3:30 hrs)
Location: KC, CA
Weather: Seeing was “okay” not excellent. Lil bit windy and after 12:00 winds picked up. Not cold at all. Survived on t-shirt. Lil bit of light pollution on south because of border patrol check-post.
Buddies: Jon Issacs. Only two of us at this dark spot. Plenty of discussions.
Instruments: My 6” dob. Jon’s 12.5 discovery dob. Williams 80mm APO, 10x50 binocs.

Got in touch with Jon thru craigslist. Overall, in this observing session, I wanted to learn as much as possible thru Jon’s 20 years experience. I didn’t have any observation plan. The only thing which I had in mind is to point my 6” dob to each and every object that Jon points thru his 12.5” dob. Compare both views. Try Jon’s eyepieces on my dob, if possible and compare both views.

This is first time I tried the laser collimator. Jon has a nice 1.25” laser collimator. Initially I collimated my scope with my collimation cap. It wasn’t perfect, but almost there. With laser collimator, I realized how easy and precise collimation can be. Jon mentioned that my mirror cell seems to be push-pull cell and described me the use of locking vs collimating screws. In the process, we realized that my focuser tube is also having some problem. Optics doesn’t align properly when focuser tube is fully inwards vs fully outwards. Need to find out more.

Tried the collimation star test on Vega, but Jon mentioned that star tests are pretty good on small apertures or refractors. For big apertures its hard to see those concentric circles. Also seeing wasn’t good enough to try it on my scope.

Double Double: Able to resolve it at 96x only (25mm x 2x). Jon was able to resolve it with lower magnification. My vision is still not fully adapted to these observations. I also tried Jon’s 9mm eyepiece (135x), and seemed like it showed me high contrast in the view than my 25mm x 2x combo.

Saturn: It was close to horizon and was still under dusk. Seeing wasn’t that great. A moon aligned on left side of the rings and titan, aligned at 4 o’clock of rings, were clearly visible in my scope. Again, Cassini division eluded me. In Jon’s 12.5”, Saturn was beautiful & crisp. One more moon was visible next to the first one I saw in my scope. Rings were nice, but I didn’t pay attention to Cassini division. Damn it !!

M57: Ring Nebula: While observing for Ring nebula, got acquitted to left eyed finder on Jon’s 12.5” dob. He also mentioned a trick for locating objects thru finder by using both eyes so that the brain creates combined image of cross-hairs of finder on the naked eye sky image and it helps to quickly locate the objects. Its was lil bit difficult for me in the beginning, but I got used to it while locating star clusters in later session.

Because of dusk, the Ring nebula wasn’t a clear view, on my scope initially it looked like out of focus star, but with Jon’s 12.5 nebulosity was clear. We should have tried it late night. Also use of filter would have been useful.

I need to confirm and understand the location of Ring nebula in the map.

Omega Centauri: Initially wasn’t able to find it with naked eye. But browse thru binocular really helped. Thru Jon’s 12.5”, it was simply fabulous. I was able to resolve the stars in the outskirts of the globular, but the center was too dense. Whole eyepiece was filled up with the globular (don’t remember the magnification). Thru my scope, it was a nice image too.. but Jon had a better contrast than mine. Again it was too low on horizon and border patrol strong lights were killing it.

M4: Fabulous view thru Jon’s 12.5”. In my scope, the M4 and globular NGC 6144, next to Antares, were in same eyepiece view. Pretty nice.

Northern Jewel Box: NGC 6231: I always heard abt it, but never looked at it. Jon pointed to it. In the binocs, APO and finally in my scope. Beautiful !! didn't pay much attention to colors.

M6: Ptolemy’s cluster: It always looks better in wide angle or binoculars.

M7: Butterfly cluster: this is first time I indeed saw the butterfly shape in this cluster. The red star the end of the butterfly body was noteworthy. With my 32mm (38x) color of the red star was noteworthy, but with 3x barlow on it (76x), the color went down to orange. Jon’s 16mm Nagler (76x) eyepiece view was much wide angular than my 16mm setup. It looked nice thru Jon’s 80mm refractor.

M11: wild duck cluster: Nice view in 12.5” dob. Unable to see the shape: flock of flying ducks. I didn’t try it in my scope. We were star-hopping just too fast :), but I confirmed the location thru my binoculars.

M80: Jon pointed to it.. I saw it and forgot :). Just too fast star hopping !!

M8: Lagoon Nebula: While looking for M11 wild duck cluster in my scope, I accidently, pointed to a nebulous object and Jon mentioned that I am infact pointing to Lagoon nebula. I have seen and pointed to Lagoon before (8 months back), but I have just forgotten it completely.

Browsed through binoculars to locate Lagoon. M6 -> M7 -> Lagoon -> Triffid

The nebula also had a star cluster located at 2 o’clock of it. (NGC 6530). Fabulous view thru my 23mm (38x). We tried Jon’s Luminicon deep sky filter on it and nebulosity indeed became brighter. Lagoon was sort of in a circular shape. Second part of nebulosity was lying 1 o’clock to this circular shape and was bifurcated by a dark lane. Also I felt that another nebulosity part was there around 5 o’clock of this circular shape. No dark lane, but separation was clearly visible. Nice view thru Jon’s 12/5” dob. was able to see bright stars at the core of the nebula. Missed the hourglass nebula inside Lagoon. Need to observe carefully and with high magnification.

Missed Triffid and Swan.. instead we moved to Dumbbell nebula.

M27: Dumbbell Nebula: the interesting part of M27 was to indeed find it. Jon gave me amazing star-hopping session with binoculars to locate and confirm dumbbell nebula.

Altair -> three stars aligned with Altair in middle. -> 9 o’clock of Altair around 5 deg N (left) -> three sections aligned: Wider pair of stars + below it, shorter pair of stars + below it, single bright star. -> In between the middle shorter pair and single bright star, there are three stars in a cluster and M71 globular is next to it. -> back to middle shorter pair of stars and move to N (left) around 5 deg. Bright star. 4 o’clock of which is dumbbell nebula. -> Pair of stars at 9 o’clock of dumbbell is aligned to point to dumbbell -> Pair of stars at 11 o’clock of dumbbell is aligned to point to dumbbell

Also, From Altair -> Move to 11” 4 deg and see the Coat Hanger. This star alignment is fabulous and looks like real coat hanger :). Coat hanger extended W (up), points directly to dumbbell nebula.

Jon’s star-hopping skills are indeed commendable.

With this knowledge of alignments thru binoculars, it took me less than a minute to point my scope to dumbbell nebula.

Another fabulous view thru my 32mm (38x) and 25mm (48x). Had filter on 25mm. really bright nebulosity. Didn’t observe thru 12.5”

Leo triplet: M65 M67 NGC3628. With my previous TDS experience, I found it easily. Bad seeing and its was at 5 deg from horizon hill. Better look in 12.5”. Was able to see lil bit of dust lane in NGC3628

Jupiter: Extremely bright. 4 bands visible. 3 moons visible on right and one on left. 3 moons were not as a pointed star but more-ever like a disk..

Canes Venatici Galaxy Cluster: Hickson68 This is Jon’s favorite object. Observed thru 12.5” dob. Kite formation – First vertex is a Bright star. Below it was a tiny galaxy (NGC5350) as a second vertex and pair of galaxies as third vertex (NGC5354 & NGC5353). All three aligned in a straight line. Pair seemed to be brighter than stand alone one. Below it, there is another faint galaxy (NGC5355), edge on, at the fourth vertex aligned in a straight line with first vertex bright star. In the same eyepiece view, way down, there is another bright star and above it a bright and big galaxy (NGC 5371)… this was brighter and bigger than any other galaxies in the view. Jon didn’t remember numbers for these objects, but pointed to them with his excellent star-hopping skills. I didn’t have stamina to find them by myself :). Also there is supposed to be 5th member in Hickson 68 group in the same eyepiece view. Need careful observation next time.

M51: Whirlpool Galaxy While browsing in Ursa-Major, I asked Jon to look for M51 and M101. Again, both of us had excellent star-hopping session for these objects thru binoculars. M51 was an easy catch. Saw thru 16mm Nagler on my scope. Compared to (32mm x 2x) barlow combo, 16mm Nagler contrast view was great. Bad seeing, so hard to see the spiral structure. On12.5” dob, spiral structure was somewhat visible, but because bad seeing and less enthu, I didn’t delve into details.

M101: Thru binoculars it was easy catch, but I wasn’t able to catch it on my scope. I was too tired I guess.

Veil Nebula: Jon pointed his 12.5” dob on both parts of nebula. In first part, central bright star (52 Cygnus). Nebulosity on both side. Right side nebulosity brighter than left side, but left side size is bigger than the right side. Second part thru my scope. Impressive view. Tried with 32mm filter. Also tried to understand the precise location. Pretty easy to confirm location because of 52 Cygnus star. Now I have read more description abt this nebula, I should be able to observe it in finer details.

Alberio: Just before leaving, I pointed to Alberio to see the colors. Immediate split with 32mm. nice golden and green/bluish pair.

Overall, It was great session. More than 20 DSOs and two planets. Two doubles. Learnt a lot abt telescope, eyepieces, collimation and star-hopping. Jon also mentioned that he liked my technique of star hopping thru clock positions. It was first time he heard abt it and indeed liked it. On the negative side, I felt like we rushed really fast in the whole session. It should have been lil bit slow with details observations and discussing those. Also whole session was without dinner :). If I would have eaten something in the middle, I would have preferred to stay longer.

Any way, Last two months or last 8-10 weeks are THE BEST time of my astronomy life. Moving to "next level" pretty fast, unexpectedly.

31st May 08 @ TDS

Date: 31^st May 08, Saturday
Observation Time: 8:30pm to 12:00pm (3:30 hrs)
Location: TDS, CA
Weather: Seeing was “okay” initially, but afterwards it improved, but still not excellent. Cloud cover was always there near horizon. Little bit breezy till 10pm. and it was freaking cold.. 44 deg F. If yahoo weather say “almost clear', then think before heading to TDS.
Buddies: Bill from next pad. Didn't talk with him much..

Highlight of the night: I cracked complete Leo constellation DSOs and surprise look of Omega Centauri.

Another constructive session at TDS. Actually I wasn't sure abt visiting TDS, because of late afternoon lunch at friend's daughter's first birthday party. So was somewhat tired.. but 25 mins nap did the magic, and ended up gong to TDS late evening.

Not many people were around.. probably 6-8 telescopes. Weather was awful when I was driving to TDS. The clear sky clock showed few “faint blues”, while yahoo weather had a doubt with “Almost” clear.

Faced some trouble with collimation.. I think primary mirror is not fully visible in secondary.. I tried my best.. but still I think its still wrong.. wasn't able to focus on Saturn precisely.. I was seeing the double images except the fine tuned point.. I should not see double images.. out of focus is okay.

**** Saturn:
Because of bad weather,, I started with Saturn. In32mm, 38x, Saturn was perfectly visible with 3 moons. 2 on one side, while one on another. Rings were visible with a separation from planet. 97x with 25mm 2x barlow, indeed showed something dark band on Saturn. Ring's overlap over the planet was clearly visible.. still wasn't able to see cassini division. Its hard to keep saturn in high mag view.

*** Leo
I followed again the cloudy night article regarding “Leo”.. page by page..

> M65 – M66 – NGC 3628 Triplet
It was again perfect catch absolutely no trouble. in finding it. all three visible in same view. NGC 3628 was really faint. View was not that great, because of bad seeing I guess.. Didn't try high magnification.

> NGC 3607 – 3608 – 3605 Triplet
Easy to find. all three lined up in a triangle. The one in the middle is really bright, other two were barely visible to me. Required averted vision. Infact I am not sure if I saw correct one.. I have a sketch with galaxy and surrounding stars and its not matching with cloudy nights.. I need to verify with ma10 sky chart.

> M95 – M96 – M105 Triplet
this time I located it precisely and in first shot :) .. The stars “p”, 53, 52 and 43 form perfect trapezoid. and in the same view finder. If we take perfect mid-point of 52 & 53, thats where galaxy triplet can be found. All three can not be in same view, some bright star, M105 and M96 are in perfect view like a right angle triangle.. if we pick up M96, then another 90 deg twist gives M95.. perfectly aligned. so all four objects for one-side angled square.

M96 is the brighter between them. M105 and M95 seemed of same magnitude. M95 seems to be the bigger in size than M96. I need to verify these observations.

> M105 – NGC3371 – NGC3373 Triplet 
3371-73 should have been 3384 and 3389.
M105 itself is a triplet. M105 is at 6 o'clock from the bright star. 3371 is at 8 o'clock. There are 3 stars lined up on right side of 105-3371 line. If we pick up the middle star, then with averted vision, 3373 is clearly visible. Simply fabulous !! 3373 is just too faint and tiny.. 3371 is bigger and brighter than 3373 and can be seen fairly.. Bill from next pad was happy to see the triplet-triplets..but 3373 was too hard for him.

> NGC 2903
Following pocket sky atlas, gave me the precise location of this guy and easy to catch. it looked like as elongated as NGC 3268, Nothing much special..

> Alpha Leonid – Regulus:
I am still not able to resolve this double star. .not able to resolve it with 6mm also, 184x.. Freaking, there is something terribly wrong.

> Gamma Leonid – Algieba:
This double star is fabulous. in 32mm, 38x not able to resolve it, but 76x showed me the “peanut” shape. companion is so close and smaller than gamma, so it looks like uneven 8 or a peanut. Both of them golden yellowish color.

I am done with Leo now.. need to move to new one.. probably virgo !!

*** Cancer
> M44 – Beehive cluster – fabulous as usual !!

> M67 – open cluster – not as impressive as M44.. its really tiny. but its hard to locate.

*** Omega Centauri
This is first time I saw this glob in my life.. From India, for the roof of my place in pune, I have seen it., but I never knew that this is THE BEST glob in whole night sky. and yesterday I saw it.. Initially thru my binocs 10x50. its almost 4 times the size of M13 Hercules glob. M13 is really tiny in front of this one. Its naked eye... 2-3 deg from southern horizon. At 38x with 32mm, it was fabulous.. not able to resolve any stars, but it was too dense more than a cotton.. really fuzzy !! 32mm with 2x barlow, 72x resolved some outskirt stars, but 25mm 2x 98x was indeed impressive... more you look in the eyepiece, the more you have adapted your eyes to the view, the more I was able to resolve the stars in it.. all of them seemed to be of same color. Again as it was too densely packed.. I am just not able to see any shape.. This was-is indeed memorable sight !!

*** Ursa Major
After dinner, I tracked few objects in big dipper. I should have read the cloudy nights article in detail.

> M81 – M82 pair:
M81 is indeed brighter & bigger than M82. M81 is edge on.. again both of them seemed to be too faint to observe anything.. again following sky atlas pointed perfect location and first shot catch !! high mag didn't help much !!

> M108 galaxy – M97 Owl nebula pair:
This was indeed hard to catch because of my stupidity. I misinterpreted the view through finder and was looking on the opposite direction of “beta”.. moment I realized my mistake, in next attempt the pair was in my eyepiece.. its indeed fainter than M81-M82 pair.. the distance between them is more than 81-82 pair. Again high mag really made them faint.. M97 is indeed brighter than M108. M97 is in perfect circular shape while M018 is elongated edge on.

> M109 - It was too faint .. I don't remember much !! it was yet another DSO.. nothing more..

> M51 whirlpool galaxy:
This was indeed great. clearly visible in 32mm, 38x.. pretty bright.. in 8 shaped with left galaxy smaller than right one. but both of them were brighter.. high mag didn't show much !!

Next time I need to watch Ursa DSOs carefully.

** Jupiter
From bill's Orion 6” MAK , it was indeed good, crispy clear image.. all 4 satellites, two on each side.. The bands were clearly visible and impressive.. but still image was not crystal clear.. too bright !! Also Jupiter was low on horizon.. similar view from my scope, but not as crispy as from bill's. I tried the red filter on it, to see the bands.. but total failure.. I think scope needs to be collimated properly..

Mistakes:
- Its freaking cold out there. A sweat shirt and jacket is not enough.
- I should right down each observation.. otherwise i forget

TBD:
- Collimate the scope properly..
- Red torch with a string

26th April 08 @ TDS

Date: 26th April 08, Saturday
Observation Time: 8pm to 11:30pm (3:30 hrs)
Location: TDS, CA
Weather: Seeing was good, not excellent.. No cloud cover.. lil bit breezy after 10pm.
Buddies: Mark from the next Pad. He was doing some photography.

Highlight of the night: Leo I galaxy triplet: M65-M66-NGC3628

Probably after 5 months, visited TDS. It was full with visitors on this public star party. Lots of laughing, cracking jokes, loud discussions and "wow"s from visitors !!

This night was too systematic for me. I followed predetermined schedule and was taking notes after every object observation. I did that for almost 10 objects. The pre-plan for "Tonight's observations" really helped.. I should always follow that. this time I went alone to TDS and indeed I was able to spend as much time as I want in my observations. I should go to TDS "alone" pretty often.

Tube Mount screws were loosen during SD-TDS drive.. so really need to tighten them.. on they return journey they became loose again.. the way they are located, It’s pretty damn hard to tighten them. I hate Celestron for the bad design of these mounting screws accessibility.

>> Saturn: My night started with "Saturn". This is first time I saw Saturn with my 6' dob. For first round observation, it was feel good object.. then late night I observed it again for details.

In 32mm eyepiece : It is a big dot with a ring shape around it. Hard to see any details. but still I am able to see two moons. One at 6 o'clock was brighter than one at 8:30 o'clock. Second one was visible thru averted vision only.

In 32mm-2x barlow eyepiece: Saturn was clearly visible. Can see the gap between planet and rings. Planet was indeed bright and some dark band at the center. rings were also nice.. wasn't able t to Cassini division, probably because of winds. Image was shaking a lot, requiring constant focusing. I was planning to put filters, but it was too breezy to be patient... so I didn't.

In 12.5mm eyepiece: It is visible really big.. but winds made it bad enough on focusing side.
In 12.5mm-2x barlow eyepiece: It was useless..

** Orion
>> M42 Orion Nebula + M43: As expected, it was a fabulous sight.
In 32mm eyepiece: you can clearly see the whole disk. It is ~0.8 to 1.0 deg wide. It feels like bright sunlight is put on its curved side.. Dark tower in the middle was in deed great.. three star alignment parallel to the tower, on right side, was great. There are 2 stars on the left side of the tower making probably 45 deg angle to the base of the tower. Head of the dark tower was brightly lighten by the trapezoid. It was somewhat hard to resolve the trapezoid with 32mm.. but still I was able to see 3 out 4. (C, A & D)..B wasn't visible. At the left-bottom side of the disk, M43 (??) was visible. It looked like oval shaped fuzzy object with a bright star in the middle. the fuzziness of M43 wasn't clear enough than that of M42 cloud. Initially I wasn't sure if it is indeed M43.. but the fuzziness and its location seems to be it. the size of the M43 oval was bigger than the M42 dark tower.

In 32mm-2x barlow eyepiece: Trapezoid was big and clear enough. I noted down the comparative magnitudes of all stars with M42 and M43. I wish I would have been able to upload my picture. Trapezoid "C" star being brightest. M43 star was also as bright as trapezoid "C" star.

My previous observation from home, indeed helped me during this observation on what I was looking for.

M42 was oriented too low in the sky around 10 deg from horizon, that’s why probably it wasn't that clear enough and it was going out the field of view really fast.

>> M78: Failed in locating M78. Just wasn't able to find it according to the map. Is it too faint for my telescope?

While observing this one and Leo galaxies, I felt that I should have more details maps for TDS. The current one which I have is Mag 7 atlas... but I guess I need like mag 10 star atlas. It helps in star hopping. or tracking in the mount :) !!

>> Cr69 Mrug-Shirsh: In deed fabulous sight. It looks like open cluster for naked eye. From 32mm eyepiece it was like all stars in perfect straight line & 90 deg alignment with a sad face at the corner.

* Canis Major + Puppis
>> M41: This open cluster is always a great sight.. lots of pairs. In 32mm it impressive, but barlow looses it beauty. "E" or twisted 4 shape or "swastika" shape describes bright stars.

>> M46-M47 open cluster pair: While looking for M41, I saw M47 with naked eye. TDS darkness is simply fabulous, most of the messier objects which give really hard time for me to observe from SD, are naked sights from TDS. That’s why TDS trip is always worth. M46-M47 pair is best seen from binoculars. They are ~1-2 deg apart and both clusters are of different type. M47 seems open while M46 seems fuzzy. I guess M47 is closer than M46, so initially I felt that M46 is a globular cluster fuzzy oval, but it is indeed a open cluster, densely packed. Probably it has more stars than M47. M46 is more impressive in 32mm eyepiece than M47. With 2x barlow on it, M46 looses its beauty. bit these clusters are ~12 deg north-east of Sirius. I should be able to find them from SD. My next pad buddy, Mark, said that there is planetary nebula in M46. I tried to look for it, but wasn't visible with 2x barlow either. He mentioned that he can see it through his 8' cassegrian.

While observing M46 from 32mm, I saw a satellite passing by, so I tracked it with telescope for almost couple of minutes. It was going SE parallel to horizon. Infact during whole TDS observing session, I accidentally saw bunch of satellites thru eyepieces.

** Auriga

>> M37-M36-M38 open cluster triplet: As usual, good sight thru binocs.. but not as great as I have previously seen. I realized that these guys are somewhat difficult to catch in telescope. Thru binocs browsing is easier, but thru telescope you really have to know guide stars and your telescope movements. M37, the outsider, is indeed impressive and densely packed than M36, middle one. Again, this packing is not as impressive as the M46 in Puppis. Didn’t look for M38.. lil bit difficult for me.

** Leo
I pre-planned this constellation. "Small wonders" article from "cloudy nights" indeed helped. the only mistake I made is I started too late ~11pm on this one. So lost the enthu to go into details.

>> Alpha & Gamma double stars: I really didn’t see any doubles.. I really messed up here. Need to read more.

>> M65-M66-NGC3628 galaxy triplet: This was the highlight of the observing session. It wasn't too difficult to catch them... and I never knew how didn’t galaxies looks from my dob. I have seen M31, but its too close to enjoy the searching aspect from the dob. The triplet looked fabulous. M65 & M66 aligned on the right side of the eyepiece. M65 on top right corner- M66 is 6 o'clock position and bottom right corner and perpendicular bisector of this alignment shows you NGC3628 on left center of the eyepiece. All of them seem to be similar in magnitude. All of them are edge on, M65 & M66 are oval-circular in shape, but NGC3628 is really elongated in shape. the cloudy nights article picture indeed helped me here. I tried 2x barlow on it, but low light was killing it. More aperture would have really helped. I showed the triplet to Mark, He was trying to photograph NGC3628, but wasn't able to find it thru his 8' Meade. He was indeed impressed with my view. I didn’t go for detailed observation as I was too tired. Need to observe these triplet really carefully. Need to spend atleast half-an-hour on this one. Saw M65-M66 pair thru 22inch. NGC3628 didn’t fir in same view, so saw it separately. The dust lane on 3628 clearly visible thru 22inch.

>> M95-M96-M105 galaxy triplet: I was too tired to for this one.. but the thought of leaving TDS was killing me, so I pointed the telescope to look for this triplet.. and guess what... it was too damn hard to find these guys... it took me almost 15 minutes to find these guys. There is no guide star nearby... Star 53 is there. Tracking star 53 from Regulus & Rho is somewhat tricky.. but after Star53, its like just browsing thru eyepiece.. In first 2 attempts I just didn’t see anything.. but in third attempt, I somewhat hit on M95-M96 pair.. they indeed are too faint than M65-M66.. But I am not sure if I indeed saw M95-M96 pair only and nothing else.. because I wasn't able to see M105.. missing piece... any way, I am sure it will take me some time to find this pair again next time.. Again no detailed observation.

** Misc
>> Double star - Delta Bootis, just above Corona Borealis:
Saw this guy through 22inch SDAA tele. Yellowish in color with blue-green companion at 6 o'clock. My 32mm eyepiece also resolved it. the distance between them seems really far for to be double star. Need to read more or observe carefully.

>> M4 in Scorpio: In SD, I spent hell lot of time to find it, and it was naked eye object from TDS. Awesome sight thru 32mm.

>> M13 in Hercules: How can I leave TDS without seeing M13. The globular cluster is miraculous. Its really bright enough to support both my 32mm and 2x barlow. With 76x, I can clearly resolve lots of stars in this globular cluster. Again, big aperture would have really helped here.. but still great sight from my 6'.

any way, left TDS around 12:30am. Forgot my passport at home, so had nice chit-chat with border patrol female :) on my way to SD.

Mistakes:
- Leo and Ursa Major constellations were going to be the prime focus for this session. But I observed Leo at the end of the session.. missed lots of objects in Leo. Whatever I observed, didn't observe them in detail. Totally missed Ursa Major.. Really need to follow the plan..
- Need couple of more jackets.. its too windy out there.
- IMP: Don't forget the passport :) !!

TBDs:
- Telerad finder. It will help to find the guide star and nearby things.
- Really good red flashlight. Tired of small red lights.
- Always read "Small Wonders" from "Cloudy Nights" before observing anything.
