Hello DSF,

This is my first report on this forum. Thanks to Akarsh and Sanath for suggesting that I post my observing reports here.

I had a chance to go observing last weekend to a dark site near Bangalore. The sky was about NELM 6+, with moderate seeing. I observed with my Lightbridge 16". The night was mostly productive, but I was a little tired after a few hours, and a little wary ( Some wild elephants had come rampaging in the field we were observing the previous night, and there were huge footprints all over the place ). So you will probably notice that my descriptions get shorter and less detailed towards the end of the list. I look forward to your comments.

1) Eskimo Nebula - NGC 2392 : Very bright. Crisp asymmetric (head shaped) inner region surrounded by a grainy halo (Pentax XW 7mm)
2) NGC 2903 : Bar easily visible, along with hints of spiral arms (13mm Hyperion)
3) NGC 1999 : On first look, appears to be a star surrounded by nebulosity. With averted vision, a dark T shape clearly visible, very crisp - with the base of the T close to the star (Pentax XW 7mm)
4) IC 434 : Horsehead easily visible as a dark silhouette on a wall of nebulosity ( Doesn't look like a horse ) (Pentax XW 7mm)
5) Flame Nebula - NGC 2024 : The entire Flame nebula is visible, almost like a photograph. Very bright, intricate details visible in the dark lanes (18.2mm DeLite)
6) NGC 2022 : Small, crisp oval shape. Not much detail visible (Pentax XW 7mm)
7) NGC 2440 : Very bright hourglass shape, with fainter tapering wings stretching out perpendicular to the hourglass. (Pentax XW 7mm)

Wow Adarsha, quite a productive weekend of observing. I can't imagine how much larger your observing log would have been if you hadn't been tired. Here in the States while observing we may have to beware of smaller creatures such as raccoons, skunks, deer, and in some parts of the country, rattlesnakes. The biggest nuisance in the spring and summer are mosquitoes. But we certainly don't have to worry about wild elephants! :)

BTW welcome to Deep Sky Forum. Looking forward to more observing reports from you. Stay safe!

Thank you, Mark. The log is as large as it is because I spent only 5-10 minutes per object :) . This is a new site for us, and I also wanted to revisit the more familiar objects and compare the views to our old site. I hope to spend more time exploring each object in the future.

Hi Adarsha,

Enjoyed your report and though I have to contend with many different types of fauna where I observe (everything from Kangaroos, Wallabies, Rabbits, Brown Snakes) I've never had to share my site with elephants!

I've only known one other amateur who observes from India. Tell us how things are around Bangalore being an amateur. Are there many others? What sort of telescopes do people have? How is the light pollution situation?

Looking forward to further reports!

Best,

L.

NGC7702,

The sky quality in and around Bangalore is terrible these days. We have been observing from a friend's farm around 130 kms from Bangalore for the past couple of years, but even that location only has Bortle 4+ skies. Late last year I stumbled upon this new location which has much better sky quality, and I've been observing from this new location for the past couple of months with a fellow amateur Aman Singh.

There's a small community of very dedicated observers here in Bangalore. Sanath, who's also a member of this forum is one who most often accompanies me, and probably the most experienced among us. I've learnt a lot from him. There are 3-4 others who are quite consistent in the hobby. I think the problem of finding decent quality skies discourages many people, who don't want the trouble of travelling to difficult/inaccessible locations for observing.

Most of us have 5 - 8 inch scopes (I've heard of a few people who have larger apertures, but unfortunately they never seem to come out into the field). Akarsh was kind enough to lend us his 17.5" Discovery Optics dobsonian for observing, which we have been using along with our own smaller scopes for the last 2 years. I recently acquired a 16 inch telescope, which has accompanied me on the last 3 or so sessions.

The small group I'm a part of has been observing regularly for the past couple of years, at least, but most of us have been too lazy to follow up after observing and share our reports :P This is my attempt to change that trend. :)

Wow, Adarsha, this is an incredible report!

I see you repeated Leo I and succeeded. I also was wondering what Sanduleak 2-21 was until I found the OOTW and then saw your post there as well. Cool object!!

Looks like amateur astronomy necessarily comes with adventure, wild life etc. We had similar discussions here in Germany with Uwe, Christian and Frank about foxes and adventuring in the high altitudes of the Alps.

Looking forward to many more reports!

BTW, did you see any tidal distortion in the Eyes? I'd that what you describe as elongation?

Very cool report. I'm sure Jimi will be glad to see that his Pentax XL is being put to good use :)


Clear Skies!
Akarsh

Thank you, Akarsh.

Yes, Leo I was much easier from Urigam. Aman was with me, and he confirmed the observation too.

I don't think I observed any tidal distortion in the Eyes. The elongation I mentioned is that of the main body of the Galaxies. But my memory has faded (and I didn't sketch, unfortunately), and I was also a little tired by the time I observed them, so I need to take another look at them and look for distortions.

Adventuring in the Alps definitely sounds like fun! :)

Regards,

Adarsha

Hi folks,

"Looks like amateur astronomy necessarily comes with adventure, wild life etc."

You bet akarsh, you bet.

One of those foxes tried to steal my jeans - (different trousers on). Fox pulled at one side and me at the other one... No joke.

But believe me, fun is somethin different....

CS!

Wow, Norman! That is a nasty fox! The fox that I've seen in the US seem relatively benign, or maybe they're just afraid of Jimi.

I like Uwe's solution to the fox problem very much! But if we tried that in Texas, we'd have a wildfire... so no way.

Great observing report! And an even greater thread!! I love this international contingent we have here at DSF. It makes for some great friends, OR's and stories! Keep them coming! :D

Coyotes, raccoons, bats etc. Those are the things I've contended with. Even walking up and down the hill at Jimis observatory had me pause with concern about a possible mountain lion. But never did I think elephants would be a concern! Just a fantastic story! :D :D :D

The most memorable animal story I have was from a very dark night at Steens Mountain years ago, when a small herd of black cows slowly walked though our group of scopes. We had retreated to our vehicles once we heard them coming, but they didn't make much noise going so slow - just the soft clump-clump-clump of their hooves and a snort or two. They blended in with the darkness of the sky and the ground, and were like four legged ghosts. In five minutes they were gone and it was like they were never there. And thankfully, they didn't leave anything behind.

nice descriptionand truly a story Howard... especially "And thankfully, they didn't leave anything behind. " :D

Adarsha - what about the central star in M 97? Did u see it? Should be easily possible with 16" under good seeing.

Hi Adarsha,

welcome to the forum and thanks for the input. Like Dragan says I also enjoy the international character of this forum. Astronomy, especially our small group of visual DS observer don't stop at any border or wall.

Nice story about the elephants. Even when we have often contact with animals here in Germany thank god no one is dangerous or poisonous. So no thoughts when we took a walk at night, even if the chocolate or the jeans was stolen. Better as a broad stepped telescope.

Your list sounds very nice, like a "best of" during the winter/spring season. I only was wondering about your "quick and dirty" observation of the cone. I found it always a very difficult object, even with large aperture, good transparency and Hß. In contrast, as Akarsh mentioned the tidals of NGC 4438 are quit easy and even with 8" a fantastic detail.

I'm looking forward to other observations of you.

Norman,

I don't think I noticed it, but my memory has faded. I need to revisit it and verify.

Adarsha

Uwe,

Thank you! I *thought* I saw the cone, it was where it's supposed to be, but unfortunately my observing partner had gone to sleep, and I couldn't ask him to verify. Perhaps I was mistaken. I'll have to revisit it and have somebody else confirm it for me.

Regards,
Adarsha.
