Date: Feb 25th 2012 Saturday
Observation Time: 6pm to 12pm (observing time ~5 hrs),
Location: Jon's Home, Boulevard, CA
Weather: good.. few lower clouds on west in the eve..but alter cleared up.. moon 5th day/~30% phase causing light pollution till 8:30pm.. lil windy at sunset and ~11pm. Seeing wasn't that great 5/10.
Instruments: Jon's 16" f/4 scope and np-101 f/7 scope
interesting things of the night were:
- first real dark session after one year gap..
- first observation of Medusa nebula, Rosette nebula, California nebula, Whale Galaxy, Needle Galaxy, plus some more new galaxy fuzzies.
- Comet Garrad C2009/P1 in Draco
- Browsing galaxies from 5" np-101 scope. When sky is clear and its dark, the small scope of np-101 can indeed show so many faint fuzzies. its very impressive. TBD: Should browse Virgo Markarain's chain through this scope next time.
16" scope with parracor: ~2070mm focal length
31mm: 67x
20mm: 103x
16mm: 130x
9mm: 230x
7mm: 295x
np-101 focal length: 540mm
35mm: 15x
31mm: 17x
24mm: 22x
16mm: 34x
7mm:: 77x
Mercury - Just after sunset, mercury visible through binoculars. while locating it, Jon cheated through his digital dumpy level for altitude and I cheated by following jon's scope location thru my binocs. Tried 31mm, 16mm, 7mm nagler on apo... With 7mm @77x, best view. Looked like a solid disk. Environment refraction showing up in apo, with blue/green color on east and orange/red color on west side of mercury disk.
Venus - Next to moon. 7mm @ 77x best view in apo. the phase of Venus is 60% from west. Lil bigger disk than mercury.
Jupiter - good view, but not the brightest view. 16" scope with 20mm Nag2 @ 103x. Big jupter disk with 4 bands visible. sothern side being the thicker band. On second band from south has a lil storm pattern, just next to the center of the band. (TBD: Need to confirm this: ~6pm). 4 moons lurking around, 2 on each side. with binocs, with hand-shaking trouble, western side 2 moons can be easily seen.
Rigel - 16inch scope, With 9mm @ 230x, fabulous view. Rigel looks like white-blue diamond with 4 streaks in each direction, like a sketch. Companion star is visible clearly with very good separation. located on North 89deg from rigel. Very faint as compared to Rigel. Lowed the magnification with 20mm @ 103x. The split is visible, but lil difficult. rigel is way too bright in the view than its companion. Jon mentioned one imp thing.. Lesser the magnification, brighter the star looks in the view. Hence Rigel dominated the view @103x as compared to 230x. this should be an easy split from home as well (TBD)
Orion M42-M43: 16" scope with 20mm @ 103x: Very beautiful view.. 3D perception with dark pillars ad the wings. Can not feet the whole nebula in one view. trapezoid visible, but only 5 stars, bad seeing. Jon mentioned that he can see/feel the red color in the saucer/wing part on upper side. I can't. M43 shows up as mediocre view as compared to M42.
Orion Running Man Neb ngc1973: Made a mistake with location. We pointed from-Inside the wing-to bigger dark pillar-to trapezoid-to dark splitting lane-just above it... its totally wrong.. Infact its outside wing-other side of the wing than m43, and few degrees away from the disk, you can spot the nebulosity. the dark region nearby sort of shows up as running man. Tried with np101, since its easier to get the judgment on location.. overall not very impressive and not very discernible view.
CMa Thor's Helmet - Impressive views with 31mm and 20mm in 16" scope. 20mm @ 103x with O-III filter is the best view. Object shows up as nice big comma shape with think disk at the top. More you focus on the view, more details you get.
CMa Tau - 103x shows up the view.. its a tiny open cluster in the view at this magnification. Central star is brighter than the rest of stars in the cluster. ~25 stars around. All stars are in outward triangular curvature from the central star, as if the ripples flowing outsides.
M93: 10x50 binocs view. Very small and tiny OC, as compared to nearby cousins M46-M47. Nothing impressive. no particular shape either.
Reflection nebula 2467 below m93: very good view in 16" sscope @ 103x with O-III filter. Easier to locate. Fainter and smaller than Thor's helmet. faint C shaped filled disk visible. in np-101, with some efforts, can see something very tiny..
M46-M47 : In np101 with 16mm @32x shows both clusters in same view. Having both of them in same view shows the beauty in both clusters. planetary nebula in m46 not visible. with 7mm@77x, PN shows up nicely with the cluster in the apo. In 16" with 20mm @103x with O-III filter, m46 is marvelous. sprinked stars now seem brighter with bigger apperture. M47 seems very marginal.. Planetory shows up as bright object in intself. neb looks good...
Jon got 10x50 Japanese Celestron regal binoculars. roof prism. but field of view is narrower than my nikkon 10x50. Tried another 7x42 binos. FoV is wider than Regal binocs, but still lower then mine. Still, 7x binocs was nice. Compared m46-m47 and nearby views in the binocs.

Aparna's @ School and that means... :-)
Date: 10th March 2011, Thu
Observation Time: 7pm - 8pm (1hr)
Location: Archstone Apts, Mission Valley, SD CA
Weather: No clouds, lil windy. Moon 6th day.
Instruments: AT102ED f/7, 7x20 Finder.
Pan 35 - 20x
Nagler 17 - 42x
Xcel 10 - 71x
Nagler 7 - 102x
Nag 7 x2 - 204x
Rigel -
35mm Pan : Can not split it.
17mm Nagler : when switched from 35 to 17mm, can not see the split, but when switched from 10mm to 17mm, then can sort of see the companion star, but its lil hard.
10mm Xcel : Not very clean split, but can see the companion star just below rigel.
7mm Nagler : Clear split. The magnitude difference is clearly visible. Rigel is not that bright and doesn't emit rays like Sirius, hence can observe the brightness of the companion. After previous dark night observation from Jon's place, can get the feeling of 10" seconds separation. Its very close at this magnification as well.
7mm x2 : Not a sharp image. 7mm was the best image.
M41 - Can locate it from the finder. Pan 35 and Nag 17 shows the best view. C shape and 2 V shapes of bright stars should be the distinctive mark for this one. (TBD: older observations)
Tau CMa -
Can not see the cluster in the finder. Hence Possible to get confused with the wrong star.
Pan 35 : barely shows the cluster, you can see very faint stars around the brighter Tau CMa, but nothing distinctive.
Nag 17 : Shows better view of the cluster. Can see around 10-12 faints stars in the vicinity. no distinctive shape. but all stars are well surrounding the brighter Tau.
Xcel 10 : More fainter stars visible. Total star count is 20-25.
Nag 7 : More fainter stars. ~35. Probably this is the best view.
M93 :
Don't remember much about this one. (Write the observation immediately. I am writing this one 4 days later.)
M46-M47 : From dark sight like Jon's place, M46 is very impressive and better than M47. But from polluted place like our mission valley home, M46 is totally washed out. M47 shows more brightness.
In M47, k shape visible, with arcs instead of straight lines. As magnification is increased, more fainter stars are visible. M47 clearly visible in finder as well.
M46 is totally washed out. Finder doesn't show it at all. Very hard to see in Pan 35 as well. It needs to be located based on M47 and nearby two brighter stars, as mentioned in the star map. Nag 17 shows some fainter stars.
NGC 2423 Near M47 : Quickly tried NGC above M47.. but nothing impressive at all. In Nag 17 barely 5 stars visible. Proabaly better from darker sight.
M48 : is out of reach. APO is almost going vertical form the patio.
M42 - M43 with UHC : M42 visible from finder.
Pan 35 shows M42, lil bit of saucer and then dark pillar is visible. two stars in trapezoid are resolvable. M43 not visible. Pan 35 fits in other two stars of the orion belt as well. Apparently each star is a small open cluster in itself.
Nag 17 magnifies the image well. Trapezoid 4 stars visible. Saucer and dark pillar visible nciely, 3 stars in parallel to the pillar are visible nicely. When added UHC filter, stars turned blue. Can only resolve 3 stars in the trapezoid. but the nebulosity increased noticeably. Saucer shows more nebulosity than Pan 35 view itself. M43 is now visible as well. The dark piller and surrounding area stars showing more depth. the nebulosity around the trapezoid seems more brighter. Second pillar shows up from the saucer, pointing towards trapezoid, but at right-angled position from the main pillar. I have see nthis pillar before, but i had totally forgoten it. but tonights view brought it back. Surprisingly, I missed this second pillar shape in Jon's 25".. I wonder how..
Nag 7 wasn't able to resolve the trapezoid. Also image wasn't stable. Nag 17 + UHC view was the best for the night.
Sigma Orionis - Read my past observations about this one in the morning. So visited it. Easy catch.
Pan 35 : shows 2-2-1 star alignment. (i.e. pair-pair-single stars). First pair is STF 761, second pair, in the middle, Sigma Orionis. Can resolve only two stars (A & E). 'A' is definitely brighter than 'E'.
Nag 17 : shows one more star in A-E.. D shows up. Fainter than E. Very close to A.
Nag 7 : C pops up in this one. Lil Further from A than D.
Overall A-B was never split. I dont know how much mags it requires (??). I should tried the barlow. (Description below says that i can not")
From internet: "Sigma Orionis consists of 5 components, the main components A and B at present only 0.3 "apart, and thus for amateur telescopes hardly separable. The components C, D and E each have a distance of 11.5", 12.7 " and 41.4 "of AB"
Mintaka : Nice binary. Easily split in Pan 35. Primary is brighter my huge margin than secondary.
Moon : Observed moon for ~10 mins In Pan 35, Nag 17 and Nag 7. Details TBD.

Binocular Browsing
Date: 17th March 2010, Wednesday
Observation Time: 9:30pm to 10pm (~30mins)
Location: Home.
Weather: clear sky.. but light polluted
Instruments: Nikon 10x50 binoc
I really never browsed thru skies from new home. though i have mounted the telescope, I really invested time into how much i can see from my patio. Also it was good refresher for some winter/spring constellations.
Heavy light pollution.. Can only see bright stars by naked eye.. NELM may be betn 3-4. Thats based on Ursa Minor. Polaris (alpha), beta clearly visible.. Gamma was in-out.. and i didn't see any other stars.
Double Cluster: It wasn't visible by naked eye.. probably few stars in there, but really hard to tell if its a cluster.. hence bino is required. Cassiopeia Gamma-Delta line directly points to double cluster. Clearly see one of the clusters. With lot of bright stars, but the second cluster is lil hard to detect..
Pleiades: Nice star cluster. 7 stars visible naked eye. 9 stars visible thru binoc. All bright stars in the Perseus upper arm are clearly visible and they point to Pleiads. Interesting thing i notices is the number of stars in the background of pleiades.. they are like bunch of stars, way fainter, but heavy in concentration behind it.. i never noticed them before.
Algol: The lower arm has only 3 bright stars. One at the joint with the upper arm Alpha-Mirfak, Algol, and one more star Rho-Per. Algol was brighter than Rho, but fainter than Alpha. dont know abt Algol's current magnitude.. need to follow it more..
M1: Failed.. Picked up the wrong location. Tried to look for it above zeta Tuari, but it should be below, inside the V shape.
M35: Can clearly see whole Gemini constellation. M35 is on Tau side way above Zeta Tau. V-Mu-Eta-M35 form rotatated parallelogram. M35, fainter..still visible..seems bigger.
M36-M38-M37: M36 is the middle one, while M38 is inside Auriga. Either M36-M38 or M36-M37 fit in the same view. ~4-5 deg apart from each others. M36 seems to be brighter and seems smaller than other two. M38 bigger than other two ??
Quick Orion browsing: M42 nebula visible. Mintaka fainter than belt stars. Mruga-Shirsha Cr69 visible. really widespread..
Quick browsing for Canis Major: M41 seemed lil brighter than M35. Probably bigger than M35?
Tau CMa: Cluster is not visible in binoculars.. it just seemed to be a bright star..
M46-M47: M47 the brighter and widespread one is clearly visible.. again the M46 the fainter one feels like to be there but not sure.. These are like two FoV away from sirius.. i.e. 10-12 deg away from Sirius.
M93: Because of recent browsing, found it easily. Seemed to be like M35.. probably fainter than it.. can clearly see it.
M44: FAILED. I thought this should have been easier to see in binocs.. but as it was overhead, was tricky.. got the location correct, betn lion sickle and proceyon, but still didn't find it.

Dark night kickoff in freezing cold - I
Date: 12th March 2010, Sat
Observation Time: 7:30pm to 12pm (~3 hr)
Location: Jon's home, Blvd CA
Weather: Initially really windy.. cold: below freezing.. intermittently cloudy.. intermittently foggy.. heavy dew.. Seeing was mediocre till 11pm.. later improved, but dew made life miserable.
Instruments: Jon's 16.5", TV NP101 APO. Didn't open my XTi-10.
Buddies: Aparna + Jon's friend Elli.
After India trip and dual-mode status :), this was first dark night session.
Had nice hot chocolate session ~8pm and shrimp curry ani Jeera rice session ~9pm. Aparna was with me till 9pm and later stayed in the house to keep herself warm.
M42 Orion Nebula: Nice view thru NP101. Aparna immediately noticed the quadrilateral stars. seeing wasn't that good. Tried 16T4 and 35mm pan.
Pleides: thru NP101.. 10 stars. Pan 35mm. Some of the main stars seems to be double.
Double cluster: Excellent view thru NP 101. Clearly shows the differences betn 2 clusters. lower right one is salt-pepper type while upper-left one seems more widespread.
M41 - NP101, Pan35 view of M41 want that great... lil tiny cluster.. thru jon's 16.5" dob, definitely a bright cluster.
M46 - M47: Impressive view of both clusters in NP101-Pan35 combo. Can fit both clusters together in same view. Again clearly see differences in both clusters. In Jon's 16.5", planetary in M46 was definitely big and bright.. filter wasn't required.
Rosette nebula in orion [New]: Saw this one for first time. NP101-Pan35. Its lil hard to grasp this object. Its really widespread and hence too faint.. if jon wouldn't have mentioned abt it, I can't even make out the nebulousity.. I am sure its hard to find.
M1 crab: Easy to locate. Crab was bright, but hard to see any details. I had better view of Crab before. Definitely seeing was poor.
Tau CMa: for got the location, Jon reminded me. Two star pairs above the CMa dog hind-leg. Pick up the uppermost pair, thats Tau. Central bright star with the star cluster around it.. sort of in a triangle shape..
M93 - NGC: Lil N-E of the Tau, lies M93.. Pick up the brigh star.. NW of is M93, while SE of bright star is the NGC ?? Don't remember anything specfic about M93. NGC is another fuzzy.. never read abt this one before. (UPDATE 03/10/2011: NGC seems to be 2467)
M76 Little dumbbell: Couple of stars from Andromeda lined up to point to the double cluster.. just above these stars you have little dumbbell. Too faint.. can see lil dumbbell shape.
Gamma Leonoid: Initially when split it from home, i think i messed up. This is lil hard to split with 60x magnification. you need lil higher mags to split it up.
M35 - Browsed thru binocs. Easy catch..

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.
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..

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

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 I
Date: Mar 28th 2009, Saturday
Observation Time: 7:00pm to 12:30pm (5:30 hrs)
Location: KC, CA
Weather: Excellent.. Seeing 4 of 5. nominal winds. Clouds in slow motion from west since 7pm and rolled all over at 12:30pm. Nominal winds.
Instruments: New Orion XTi 10, Jon's 16.5' and bunch of naglers, panoptics and uwans :) yey !!
Buddies: Jon
Total Objects : 69 = 57 + Markarains Chain 8 + Virgo Zoo 5
New Objects : 18
Messier Objects : 46 = 42 + Markarains Chain 2 + Virgo Zoo 2
Attempted Messier Marathon.. Objective was to capture as many M objects possible before cloud rolls over around midnight. Spend time with Jon while browsing.
Because of Messier marathon, overall didn't spend much time in oserving objects or puting higher mags. but tries to locate objects and remember their locations. Jon showed few interesting objects along the line.
Print out of messier marathon sequence indeed helped as a observation schedule.
Because of KC valley mountains, lost all objects till M33 i.e around 30deg of W view is blocked, so started with: M45 in binocs and perseus double cluster in 10'.
Double Cluster: Lower one bigger then the upper one. One is loosely connected and contins lot of bright stars while another one is concentrated and full of faint stars.
M103 OC (New): Seems closer to the star Delta, but browsed on wrong side. At low mags, M103 seems to be 3 stars in triangle fashion, but middle one is a pair. At lil higher mag, you can see that left star is full with other faint stars. only left star is the brighter one in the herd. (Need to confirm this observation. (TBD ??)
M52 OC (New): Though away from any nearby star, easy to find. Its indeed a tight faint cluster, but a lone bright star in the cluster.
M76 PN Little Dumbbell (New): Easy catch. Impressive.
M34 OC (New): Next to Algol. Y shape in center. All stars are bright.
M45 Pleiades (New): In 42mm eyepiece, all sisters fit well, there seems to be lot of tight doubles inside this one. No nebulosity. surprisingly this my first entry documented for M45. I have seen it hundred times from binocs.
M42-M43: Impressive view M42. Watched it multiple times during whole night. Just after sunset, trapezoid visible, no nebulosity. After dark, view in 16.5' 35mm panoptic view was the best i have ever seen of M42-M43. All 70deg full of nebulocity. Never realized that M42 nebulocity is so huge and impressive. Trapezoid: Tried for E-F. Seeing was just too bad. never saw them.In the process i realized that, though whole sky seems so impressive from dark place, in reality the seeing can indeed be bad. Thats the difference betn transparency and seeing. Trapeziod or planets are good tests for seeing.
Running Man nebula: Visited near by Nebulosity with 3 bright stars visible. Dark running man didn't show up..obviously.. probably need a filter.
M78 Neb: I told Jon abt my failed M78 attempt couple of days back form home.. Sigma and Alnilam line points to m78, but the object is not nearby any prominent shapes, probably there is UMa shape on right side of this object.
Flame Nebula (New): Also tried flame and horsehead nebula.. both of them seem to be on opposite sides of sigma (TBD ??). Glare from the nearby star kills the nebulosity, so actually you have to keep the nebula and star at the edge and hide the star, so nebulosity is prominently visible.
Horsehead Nebula (Failed): According to Jon, he pointed the scope at precise location, but didn;t see anything at all. We already had H-beta filter on, but still didn;t see anything. this one is really hard.
M79 GC (New): Easy catch. Follow the dagger from Orion to alpha-bet in lupus. Contimue the line and thats where M79 is. Its impressive. At 38x, yo ucan see the bluish globular. high mags help. At 76x outer edge stars are resolvable. 110x didn;t help, not able to focus.. bad seeing.
Tau CMa (New): Jon mentioned abt this Masterpiece. Small concentrated cluster around Tau CMa. Tau is only bright star in this cluster. Infact not sure if its part of the cluster or not. (TBD ??). Should be visible from home.
M41 OC: Impressive. E shape visible clearly. All bright stars.
M47 OC: M47 k shape didn;t impress much. Actually all stars are sort of bright so k shape or oph shape not very impressive. From light pollution at home, this object is better.
M46 OC and PN: Marvellous. Light pollution kills all stars making them too faint. but from dark place, all stars show up smoothly. Planeotry is easy catch.. My averted vision location, seen from home, is indeed correct. From dark place it pops up. higher Mags helps. Size of PN is almost same as lil concentrated stars above it. Thru 16.5' it was beautiful, Also jon's 28mm UWAN 82deg makes it much more impressive. Colors of PN in 28mm UWAN were much better than My 32mm x2 combo.. Good example to see eyepiece differences.
Thor's helmet (New): huge. nebulosity is enormous. Shape not discernible. Jon mentioned won;t be visible from home. Its nearby M46-M47, but i don't know the location. (TBD ??)
