Being Obsessive.. Part I

Date: Mar 5th 2011 Saturday
Observation Time: 7pm to 11:30pm (observing time ~3:30 hrs),
Location: Jon's Home, Boulevard, CA
Weather: not great.. partly cloudy so looking thru patches. No wind. Seeing wasn't great 5/10.
Instruments: Jon's new 25" f/5 Obsession telescope
Buddies: Jon & Ashwin

Lot of new things to begin with for this observing session.
- Jon's new 25" obsession scope. Its massive. Need to climb 8 foot ladder to observe at zenith.
- First session of 2011
- Welcome Gogol session.
- Finished all 110 messier objects.. not in one night, but in 3 years period :). All messier objects are observed atleast once now. It was sort of 3-year messier marathon.

Ashwin joined for this session, first time at Jon's place.

Recently Jon purchased 25" obsession telescope. It is a used telescope and has a chip on the back side of the mirror. Jon got an excellent deal for the scope without much compromise. Its obsession scope #511.

Irrespective of the massive size, the scope movement is very smooth from the top of the ladder. It shows really nice views.
Mirror: 25"
Focal Length : f/5 3110mm. With parracor : ~3658mm
So now a 31mm Nagler low mag eyepiece from 16" scope, suddenly gives 100x view in 25" scope. Its not low mag eyepiece anymore.

Can clearly show 500x zooming with sharp images. Can easily go to 800x with decent views.

The Collimation took longer than expected. Jon is still getting familiar with the movement of secondary mirror screws. Primary alignment was quick. Also, the collimation stayed fine whole observing session. Considering the amount of scope movement, its indeed stable.

For such a big scope, generally it makses sense to observe all the objects in the vicinity and then to move on to the next location in the sky. But becasue of clouds, we ended up jumping from one location to opposite one and moved the scope and ladder a lot. We ended up doing ~10-15 circles/360deg rotations with the scope, during the night. Still, I am listing the objects per constellation and with the flow of the observing sessions.

Perseus
========
M76 - little dumbbell nebula: Started the night with M76. not a object that will impress immediately, but details on M76 was nice. Can clearly see two lobes, sort of in hourglass shape. The brightness was enough. Considering mirror cool-down time and cloudy weather, it indeed showed more than enough details on the object.

Orion
=======
M42 - M43 orion nebula : Switched to Orion M42 masterpiece. In 31 Nagler @ 118x, the eyepiece was fully covered under the nebula. the saucer, the pillar and the trapezoid was fabulous. Very bright. More you look at it, can feel the depth.. Had3D effect. Trapezoid clearly shows 6 stars. Double speed focuser indeed gives pinpoint stars of #5 and #6 in trapezoid. With 20mm Nagler @ 182x, magnifies it to the dark pillar. In contrast, the trapezoid and the illumination of the gas around it was very bright. Because of bright nebulousity all around and the central pillar being so dark, sort of looses the typical shape. M43 itself shows lot of bright nebulosity. Talked about running man nebula nearby, but wasn't sure about the location. Next time TBD.

M78 - The nebulosity pops up because of bigger aperture. A Bright star in the view. Hard to remember, because of lack of discernible shape, but definitely filled ~10% of the eyepiece.

Rigel - Visited Rigel multiple times in the night. At 118x can clearly see the companion. Rigel was sharp, but the companion wasn't.. tried to focus, but it still seemed like blurry disk. companion ~9.8" separation. Very close to Rigel. Later visted it again with ~400x. This is to compare with Sirius. Just wanted to get a judgment on how 10" separation looks like at ~400x.

Canis Major
============
M46-47 : with 20 Nagler, at 182x, the hwole view was filled with bright stars of M46. In reality, M46 has fainter stars than M47, but with large aperture of 25" makes M46 such a bright object. the planetory nebula is in the view on the right-bottom side. A faint star at the center of it is visible. not sure if its part of the cluster or the planetory star itself. At 182x, M47 is infact dull object, though it has bright stars its really sparse object. Hence nothing impressive in their. With 31 Nagler, 118x, both objects never fit in the same view and hence the beauty of observing both in wide-view is sort of lost. but 31 nagler still shows M46 as an impressive object.

M93 - This was yet another OC.

NGC 2467 - object opposite to M93. - The nebulosity in the object is very distinct in the big aperture. Sort of big C shaped nebulosity. Next to it is the Open cluster in V shape, similar to Taurus.

Sirius - Tried splitting Sirius. Difficult part here is Sirius is too bright compared to the companion and hence very difficult to observe the companion. Also its only 10" seconds apart. Only thing I knew tabout it is that its following sirius. Hence i kept Sirius barely out of the view and tried to look for the companion, but it was hard. Sirius light rays were causing trouble. Secondly wasn't sure how much 10" distance seems at 400x. So thought that another faint star is its companion. To get the judgment on 10" separation in 400x, tried Rigel. that proved that the faint star i was looking at was wrong. 10" is still too close in 400x. FAILED to observe the companion. Need better seeing/stability for this one.

Beta Monoceros - Observed the triplet, during the last session of observing. Triplet system with a tight bright pair. No colors, all three were yellow.

Ursa Major
===========
M81-M82 : M81 seemed like a big elliptical fuzzy object. Very bright. But M82 was more impressive, with distinct edge-on and some motteling on it at the center in Y axis.

M51 : Visited M51 probably 3 times during the night. The object moved from horizon - 5deg to -30-45 deg in 3 hrs. In the last session, the details on the object were clear, Can easily trace the spiral structure fomr the center to the connecting NGC galaxy. Actual Connector betn both of them was not visible. Some Nebulas or brighter regions in the spiral of M51 were visible. Don't remember the exact location of these regions. More eyepiece time + dark adaptation, gives more details on this object. Definitely saw more details on M51 visually for first time.

M101 : The brighter part at the core is visible. Jon mentioned that this is a big object and can not fit in the view itself.. I didn't see much in this one except the fuzziness at the core.

Canes Venatici
===============
Galaxy Quintet near M51 - Hickson 68 - NGC 5354 + 4 more : This is actualy in CVn and not in UMa. Jon pointed to this one.. Seemed like typical Jon object :). Very faint galaxy group, made up of 5 galaxies. Two of them were (relatively) bright, while remaining were barely visible. Very faint. The brighter NGC 5354 is of mag +11.38, while the lowest one on the left NGC-5358 is of 14.57. this is just to know that Jon's scope goes till +15 mag, without much trouble. Have I seen this one before? (YES, I have. check older observations)

Fuzzies Everywhere - III

Continued..

During this time, I started with Leo fuzzies. With low mag 35 pan @ 35x can clearly see 2903. Its indeed small but still bright.

Leo Triplet 3193 ben Gamma and ?? star.

Leo Gamma doublet, Again i looked at wrong location (inside the sickle) on this one. Its outside the sickle towards the body. Its on eastern side of Gamma Leo. Can easily see it thru my 10" scope 17T4 combo.

While looking for M95-M96-M105 triplet, i accidentally ended up at k-leo galaxies. They seem lil different than what i have seen thru Jon's scope.. two of them were really bright (i.e. 3367 and 3377), didn't see any other.. Again after relocating I got 95-96-105 triplet.. triplet within 105 was also visible. and thru that was able to move to k-leo gals also.

When moved to M65-M66-3628 combo, M95 triplet is definitely separated more than m65 triplet.. my expectations from m65 were really high being brighter, but din't get any impressive view thru my scope 17T4 70x. Mentioned it to Jon, if seeing/transparency is okay.

Checked for 3607. In 17T4 @ 70x can clearly see 3607-3608 pair. 3605 was also not clearly visible.. required lil higher mags. I believe I also looked at 3599 (New) nearby, thru jon's and my scope.

Jon was tired of fuzzies, so he moved to Saggi and Scorpio, while i continued my fuzzy hunt with Ursa Major.

Started hunting fuzzies in UMa systematically star-by-star.

From Alpha UMa - 1st star - Dubhe:
M81-M82 - indeed marvelous with low mags and high mags. With 17T4 @ 35x can also clearly see two nearby ngc objects. M81 being at center, M82, ngc3077 (new) and ngc 2976 (new) forms perfect Y shape prongs. 3077 is way smaller than 2976. Infact data sheet shows that, though smaller, 3077 is a magnitude brighter than 2976.

Near Beta UMa - second star - Merak:
M97-M108 - Fits in same view (17T4 ??) M97 brighter and more bluish than m108.. m108 seemed to be edge-on type. Nearby NGC 3631 (New) is also an easy catch. Moving from 108-97 in direct straight line or from finder to a nearby bright star HR 4363 helps.

Near Gamma UMa - third star :
M109: don't remember much..seems like it has bright core (??).. missed the nearby ngc object.

M106 - Opposite to alignment of M81-82-Alpha-Gamma stars, lies 106 towards CVn. Observed ngc 4490 near Alpha Cvn. Dont remember much. switched to M106, which is at exact center of Alpha Cvn and Gamma UMa. seems visible thru finder.. M106 seems to have brighter core.. nearby satellite ngc object clearly visible thru jon's scope.. must be 4217 (New) (or 4248 ??)... hardly visible in my 10" scope 17T4 @ 70x..requires more magnification.

Had a quick glance at M63 and M94. just saw so many galaxies that don't even remember much in t details.. need to spend some time on these objects with higher mags.

M51 whirlpool: marvelous view of the pair. Can clearly see the spiral lanes. More time i spend on this one, more details pop up in the eye. In M51 seemes like brighter star-like spot on the spiral arm. NGC-M51-Brighter star like spot. Need to read more abt this one. ???

M101 : closer to 7th UMa star. M51 is on southern-easter side of this tar, while this one is on northen easter side. almost at the same distance. don't remember much.. just too many fuzzies for one night. It needs to be observed with high mag ???

Night of Leo Fuzzies - II

Continued..

M81-M82-ngc3077 - Can't fit these together in Nag31 16" view..probably just at edge-to-edge.. really surprised. infact next to m81, there is ngc3077. indeed nice view.. somehow never seen it before..

Omega Centuari - Jon pointed to the masterpiece.. Lil low on the horizon.. Scope was almost horizontal. Easy to catch.. you can feel like you can see it naked eye. Marvelous view through the Nag31.

M4 - Scorpio on SE horizon, tried M4.. indeed smaller and fainter than expected.

Antares - bright red view..

Markarains chain - browsed through markarains chain.. Again i don't know what are the galaxy numbers.. need to do more research and get comfortable with it.

M95-M96-M105-NGC 3371-3373 - Went back to Leo again.. Location was correct... When looked throu the view, can clearly see the triplet. but felt that the messier triplet is too small for the view. I mentioned to Jon that M105 is the triplet in itself.. we zoomed in with 20T2, but didn't see anything..i mentioned to jon i had definitely better view of whole thing thru my 10" than our current view.. After a while, when Jon browsed thru, we realized the real mistake.. the initial triplet we looked at itself was M105 triplet :).. and M95 and M96 were way too apart from each other..with lowest magnification, the scope 2000mm FL with 31 Nag 66x was still high to fit all messiers in same view.. indeed surprising.. need to read more abt comparision betn 65-66 and 95-96-105.

Fuzzies next to K Leo 3367-3377-3412-3346-3348 - The K leo star is next to m105, but interesting thing is there are 5 more galaxies near it.. though they are fainter than M objects, they may be of similar brightness as triplets in m105. 3 of them are on one side and closer to k leo.. 3367 is betn m105 and k leo.. 3377 is 2' clk of k-leo, while 3412 is aligned with 3377 and k-leo... Easy to catch.. while 4th one 3346 on opposite side and lil farther. The 5th one 3338 wasn't able to find it.. was loosing the direction.. any way just browsing thru these gals was just awesome.. the iphone s/w is infact showing more gals in this area.

Triplet 3193-3190-3187 - While looking for Gal pair next to Gamma Leo, Jon pointed to me to this triplet betn gamma and zeta leo stars.. First one on right next to a star, second one on lil-further and top of the star. third one still further above second one.. third one seemed to be really faint and edge-on style.

Dark night kickoff in freezing cold - II

Continued..

Eskimo nebula: The middle star jumps right at you.. if seeing is better, probably can see more details. bluish disk..very bright in the center and fainter outside..

Double planetary - In Jon's 28mm UWAN ~75x, way too tiny to see this one..but definitely you can see it. The clear 8 shape visible.

M81-M82: location. I always miss the location of this one. Pick up first and 3rd star in square of UMa and draw the digonal line that points to 2-3 star cluster, just below SW of it is M81 and M82. You can defintely see the pattern/texture on the edge galaxy. The pair is clearly visible thru binocs, once you know the location.

M51 Whirlpool galaxy: Not the greatest view of whirlpool. bad seeing..

M next to the third UMa star (seems M109): in jon's 28mm UWAN, 3rd UMA star and M?? (M109) is visble in the same FoV.

M36-37-38: binocular browsing.. Jon mentioned about some ngc next to M37??

Leo triplet M65-66-3628: Jon pointed to it. 3628 fainter than other two. All 3 in same view (with uwan 28 75x ??). 3628 elongated and bigger in length than others ??

Jon's galaxy pair in UMA: Two faint galaxies in the view. If you continue the tail of UMa, same distance as 5th & 7th star along the tail. (UPDATE 03/10/2011: From the location, seems to be Hickson 68 in CVn)

M3: Jon pointed the location.. bit tricky.. visible thru binocs.. Outskirt stars are clearly resolvable. higher mag helps..

Sombrero Galaxy: Jon pointed the location.. lil tiny than what i was expecting. elongated.. but no sombrero structure visible.

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 - II

continued..

Double next to Tau CMa (New): while looking for Tau CMa, saw this double yellow-blue pair. Don't know the name yet.. Tau CMa is on southern side of Delta CMa, while this double is on northen side of it.. really wide double..

M46-M47: To compare 15mm, 24mm and 25mm eyepieces, moved to M46. At 15mm 80x and 24mm 48x PN was visible nicely.. but jon asked me to try his WO 28mm UWAN, and it was marvellous image.. 82 deg widefiled with whole star cluster crispy clear in the view.. and PN was also clearly visible.

With Jon's 28mm UWAN on my scope,

Thor's Helmet: Failed..Tried to locate this one, but failed.. too low on horizon.. porbabaly ended up at M50.. need to learn this star hop (??)

From low horizon, moved to overhead constellations..

Leo M65-M66-3628 triplet: Impressive in UWAN, 3628 is clearly visible, perfect edge on, but both ends are sort of blown up..

Leo Gamma Doublet Gal: Again nice pair.. easy to catch.. these are really tiny and faint galaxies.

NGC 2903: Edge on - Easy catch @ head of Leo.

M81-M82: Browsed to M81 and M82. while finding the exact location, ended up with near by NGC3077. M81 and M82 both bright and fits in same uwan view. NGC 2796 nearby.. In Jon's 16.5" M81 looks nice.. the middle vertical dark lane was clearly visible.

M108-M97: Easy catch. Both in same view.. Owl is definitely brighter than the galaxy. din't try to increase magnification so that can use uwan much more.

M109: Its a huge galaxy, don;t remember details..

M51 whirlpool: M51 and nearby NGC are visible clearly.. the conneciton betn them not directly visible.. m51 is bright.. occastionaly, coupel of stars/bright spots on N and NW poping up.. with averted vision had spiral structure feeling.. And all this just in 28mm uwan..42x !!

continued..

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.

Messier Marathon - Part III

Continued..

Virgo-Coma Galactic Cluster: Jon showed me in 16.5' with 35mm Panoptic. Marvellous.. 9 galaxies in same view. 5 of them were pretty sharp. This is a galactic heaven. Don't know which objects I saw, but seemed like Markarain's chain. Wasn;t sure abt the location.

As per star atlas, started with epsilon virginis and must have gone towards M60-M59.. not sure.. tried to browse nearby.. but its easy to loose yourself easily in this galactic zoo. Star hopping in this area is real skill. Need to read more on this one. (TBD ??) .. but its unbelievable view. Can spend hours on this one.. and soon I will :)

In my 10', 42mm 30x view, looks good, but Jon let me borrow his 28mm UWAN with parracor. WOW !! no words !! The field of view 82deg rules ..keeps lot of galaxies in same view. with paracor, view was awesome.. but with parracor, every star is tack sharp. Also tried 22m Nagler.. Hssh !!

For rest of the night, i used Jon's 22m Nagler :) (50x) !!

- Ursa Major:
M81-M82 Bode's Nebulae: Easy catch, extending Alpha-Gamma line, towards pole. Bright pair, barely in 22mm. M81 vertical dust lane visible (??). In 16.5 impressive-bright view. Wish jon would have increased the mag.

- CVn:
M63 Sunflower: Bright and big, unexpectedly.

M51 whirlpool: Galaxy pair merge clearly visible. I guess because of nagler, they look so bright. Smaller than M63.

- Bootes:
M3 GC: Jon showed the location. Still tricky to find it. MArevellous globular.. bright-bluish. Probably can resolve some outer skirt stars with 22m.. high mag required.

- Coma:
M53 GC (New): Identifying Coma constellation was headache. but once found alpha, M53 is an easy catch. Beautiful GC. Smaller than M3.

M64 Black Eye (New): Yet another.. but easy to find.

Seems like i was too tired... just too many fuzzies for one night :) !!

- Ursa Major:
M108 - M97: Both M97 Owl nebula and M108 fits in same view. Nebula is brighter than galaxy. galaxy seems elliptical.

M109: Yet another fuzzy, don't remember much.

M40 (New): Its double rather than any fuzzy. Messier mistake.

M101: Lil tricky, may get confused because of NGCs nearby. but big & bright.. feels up whole eyepiece.. this seemed to be of unusual shape.

- CVn:
M94: Easy to catch with star atlas. Yet another galaxy.

M106 (New): Failed.. too tired.. thought that saw it thru binos, but that can not be..its too faint for binos.

- Hercules:
M13 GC: Sort of in clouds. Still got it. Way bigger than M3 also.. too bright..but wasn;t clear..seeing was just too bad..


TBDs:
- Are we/milkyway part of Virgo galactic cluster?
- Field stop of an eyepiece
- Barlowed laser collimator
- T CMa
- Nagler-Panoptic eyepieces on 10"
- Trapezoid E-F stars: Seeing is better in TDS than KC

Lot of fuzzies while browsing thru the sky. Impressive to see how many "things" are there in the sky.

First Dark Night with Orion XTi 10 - I

Date: 17th Jan 2008, Saturday
Observation Time: 6:00pm to 11:30pm (5:30 hrs)
Location: TDS, CA
Weather: Excellent.. Seeing and Transparency 8/10.. winds picked up around 11pm.
Instruments: New Orion XTi 10, Rick's 12.5" dob, Tony's 8" dob and Bret's 24" dob. Bunch of new eyepieces.
Buddies: Rick, Tony and Bret

Total objects: 40 DSOs + 2 planets
New : 11

Best of the Night: M46 Planetary Nebula and All tiny galaxies in Leo.

First night of the new year.. looks like astronomy for this year started way too early :).. hopefully continues like this..

Objective of the night is to:
- test the new scope
- compare all eyepieces
- check intelliscope performance and functions
- some sky browsing.

Vertical Alignment. Hard.. TDS public pad is indeed slanted a lot.. this is gonna be tricky.. Is vertical stop connection to the scope really required for intelliscope ??

Connected Telerad. Placement is not ideal, but not bad either.. didn't have much choice because of finder location.

Rick from next pad helped to do the collimation with laser collimator.. secondary was lil bit hard to align.. somehow its really tight.. don't know why.. do i need to loose the central screw lil bit ?? ..any way will buy Howe gladder laser collimator this week.. Rick showed me a way to collimate without barlow.. sort of.. he mentioned that barlow is really not required.. only trouble is moving up-down to see and move screws.. that should be okay..

Worst mistake of the night.. Intelliscope battery down.. when i checked the status form home.. it was up.. but i didn't realize that its not good enough to see at night.. i have used this thing in Nov, and it was good.. i must have left it on since then :(..needs new battery now.. the problem was i wasn't able to use it for whole night.. that was one of my objectives at TDS today..zero outcome.. next time !!

Venus: Impressive. 45% phase. Too much waving. Probably scope also wasn't cooled down. MAx magnification with 9mm expanse.. 4.5mm failed.. higher mags didn't help much to see any details.. in the view.. i noticed that when Venus at the edge of eyepiece, it had violet tint on west i.e. bright side. but as the Venus moved to center of the field of view, the violet tinge reduced. Again increased as the movement towards the edge of the eyepiece.. is it indeed eyepiece ?

M42 Orion Nebula: Spent really long time tasting eyepieces.

Tony's celestron axiom 25mm on 8' dob: 82deg field of view.. impressive view.. star crowded sky.. Orion in the middle.. dark tower visible.. trapezoid visible.. second dark tower perpendicular to main one clearly visible..

40mm GSO: View wasn't bad.. 60 deg FOV. but stars at the edge were stretched and looked like streaks.. bad eyepiece at the edges.. Again barrel length was trouble so have to take out the glasses.. second tower wasn't visible..still good view.

32mm E-Lux: Impressive view.. stars were fine. trapezoid barely visible.. i think 3 stars of it visible. second tower was visible, but not yet clear..

25mm 1.25' and 25mm 2': Second tower visible, but not as clearly as tony's. ..hmm eyepiece quality :) .. $150 ?? trapezoid visible.. compared both my 25mm eyepieces. FOV is larger in 2' vs 1.25'.. definitely.. but i felt that 1.25' is lil bit better in contrast as compared to 2'. i was able to focus better on stars with 1.25'.. also m43 nebulous area was better in 1.25'

10mm X-cel: marvelous view.. all nebulous details in second tower visible. Trapezoid 5th star was in. wasn't aware that there is 6th one two..

9mm expanse: surely better field of view.. no other difference than 10mm x-cel.

35mm Teleview Panoptic on ricks 12.5' dob: 07deg FOV. MArvellous view.. second tower was there..lil bit in-out of focus. still picture was marvelous. 3 out of 4 trapezoid visible. Still with high mags didn't see 6th star. rick tried to explain me the location, but didn't find it.

M43: In 25mm dark region within M43 visible.. western part (left) definitely larger than eastern (right)

Perseus double cluster: Rick TV 35mm view impressive.. pinpoint stars.. mine 32mm was fine too.. stars were perfect pint point.. that shows precise collimation..

M31 Andromeda: Rick TV 35mm: Clear view of whole M31..Dust lane was good.. indeed was getting a feeling of it.. M110 and M32 visible.. but too tiny. My 40mm: M32 & M110 wre but too tiny.. but this eyepiece indeed shows the length/glow of m31.. just too large.. dust lane wasn't much impressive. My 32mm showed the dust lane.. but it wasn't as good as rick 35m.. again eyepiece quality..

M33 Triangulum: Forgot the location. Rick got it.. fuzzy object.. no details visible ..m33 thru bret's 24inch and bino-view marvelous.. hydrogen region was visible at right corner.. also watched so many dark lanes in m33.. the whole view was full of it.. also sort of got a 3d perception.. must be because of bino-view. In bino-view mag calculation is different..view was around 150x. thru my 32mm or higher mags, just a fuzzy object, no details visible... aperture helps.

Blue snowball NGC7662: okay.. not that great.. really tiny.. i was expecting more.. compare with Jon's 10' dob.

M81-M82: impressive. M81, on left, seems as big fuzzy.. M82 on right seems edge on.. One tiny galaxy NGC3077 (new) right angled above M81. Used 40mm for finding.. 32mm view good.. 25mm was better and showed the dark edge on M82.. 10 mm possible.. but no other details..impressive view thru Rick's 35mm panoptic 70deg FOV.. Tony's 25mm wasn't that impressive considering 80deg FOV.. too much magnification..

M41 OC in CMa: Visible naked eye - don't remember much.. Thru 40mm: Curved lines

M46-M47 OC pair in Pup: Thru 40mm.. M46-M47 barely fits in same view.. M46 stars are pinpoint and concentrated like double cluster.. while M47 is normal dispersed bright stars. 25inch SDAA scope thru 31mm (2500mm focal) shows a nebula.. impressive view. In the nebula itself there was a concentric circle (i think).. indeed impressive.. Thru my 32mm. barely visible for me.. 25mm impressive.. bluish visible.. cluster and PN in it indeed impressive.. 6mm was still good - 10mm lost it.. M46 farther than M47.. PN is actually not in M46 but much closer to us than OC.

M50 in Mon (new): Yet another OC. Don't remember much.

M93 in Pup (new): Really tiny OC.. salt-paper.. too low on horizon

M36-M38-M37 in Auriga: Quick browse. Was overhead. lil bit hard to catch it.. Visible naked eye m36-m38.. bino view was great for all three.

M44 Beehive OC in Cancer: Thru 40mm eyepiece..impressive.. beehive visible.. but 25mm view better to see beehive triangles.

M67 OC in Cancer: Yet another.. nothing impressive..

M35 OC in Gem (New): SDAA scope impressive.. bright yellowish stars. and tiny OC NGC1258 (new) next to it.. this ngc looked like M93.. fine view in my 32mm also.. seen it before thru binocular

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
