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..

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.
