3. Whirlpool Galaxy (M 51) -- Oh my God! This was one of the most divine sights in the eyepiece! The galaxy appeared like a grayscale version of its photograph by Dr. Suresh Mohan stuck in the eyepiece:
The two spiral arms were clear and the connection between the two galaxies could be easily seen. The view at 140x (which is what I've described) was simply breathtaking!
4. M 74 (The Phantom) -- This galaxy in Pisces showed us three spiral arms at 140x. It was really beautiful. (Users of Debian GNU/Linux would have probably come across a blog post about the Debian logo resembling M 74's arms -- and we saw just that!)
5. NGC 1365 -- One of the bright galaxies in Fornax, it showed us _distinct_ barred spiral structure with two spiral arms as seen in the photograph (again at 140x)
AMAR : Good one! Worth commenting as compared to others.
AKARSH : 6. Horsehead Nebula -- Pavan finally managed to see the Horsehead nebula in Keerthi's 8" telescope. I didn't bother staring at it again, so I don't know -- maybe Pavan can update the group.
7. NGC 1300 -- This barred spiral in Eridanus showed the bar very clearly, and some structure at the ends of the bar. One spiral arm was visible, but the other was a bit too faint.
8. NGC 1187 -- Showed hints of spiral structure and bar, although spiral arms were not distinct.
9. NGC 1049 -- This faint, tiny globular belonging to the Fornax Dwarf system was seen as a tiny fuzzy spot.
AMAR : In the Southern sky, we also saw a small easy fuzz which was NGC 1049, the globular cluster of Fornax Dwarf galaxy. I was expectant of spotting it's parent dwarf galaxy too, but a reality check of the image on internet on spot, completely dissipated our confidence. It was 'terrribly' diffuse and with sparse stars.
AKARSH : 10. NGC 27 -- This very faint galaxy was a tiny smudge that was very hard to detect. Thanks to the internet connectivity, we were able to confirm the exact position against DSS images and find this object.
11. NGC 22, NGC 16 -- Two fuzzy patches of light. Nothing more to say. :)
AMAR : Wow, we finally managed to nail the double-digit NGC's with these 3 observations...quite a fantasy pending since long.
AKARSH : 12. NGC 1232 -- This showed hints of lots of spiral arms, although I could not see anything concrete.
13. NGC 891 -- Showed central bulge and a long dust lane, almost like a black-and-white photograph. (Just like the view on the 19th that I tweeted about.)
14. Rosette Nebula -- We were able to visually detect the brightest portion of Rosette Nebula in the eyepiece. It spanned a semi-circle. We could not see the other parts.
15. Amar showed me two comets. He will share the details.
Just to share, the comets seen this day are 81/P Wild and C/2007 Q3 Siding Spring.
AKARSH : 16. M 97 -- The owl nebula showed the two "eyes" of the owl without OIII filter at 140x magnification. They were hardly distinguishable from the rest of the nebula. I confirmed the orientation of the eyes using images and it matched.
17. M 100 -- I think I was able to see the beginning parts of the brighter spiral arm of this galaxy. Confirmed the orientation with field stars.
18. M 81 -- We were able to see hints of spiral structure the previous night itself, which Pavan confirmed with a photograph. I'm just mentioning this here because I forgot to mention it earlier. We revisited this object, but didn't spend much time on it.
19. NGC 2683 -- Edge on spiral, showing hints of a dark lane. Pavan, Amar and Keerthi saw the dark lane clearly, but I wasn't able to. The central bulge was clearly there.
20. NGC 4565 -- This edge on spiral was really, really beautiful. It was extremely long, sported a dark lane, and had a nice central bulge. A marvellous sight indeed.
21. Jupiter -- With perfect, fresh collimation, we got a crisp view of Jupiter with structures in the cloud bands etc.
The last three days of observing with the 17.5" scope has been really exciting. We enjoyed these wonderful views, thanks to people on the Cloudy Nights forum, who educated us that 2mm exit pupils are "usually" the best for DSOs. We noticed that a lot of features became evident with the raise in magnification, particularly the spiral arms of M 74 (which were hardly visible otherwise).
Maybe I should blog about these wonderful nights I spent under those Bortle class 3 skies of Coorg -- they were wonderful and the 17.5" really lived up to our expectations (while the 8" exceeded them, like Amar points out!).
AMAR : Yes you should actually blog of your four-five night observing-spree. The last we both were involved was exactly two years back!
My greatful thanks to you and your scope, for making the witnessing of unique distant wonders sitting right on this teensy planet, possible. :-)
