NGC2035 Seagull nebula....I think?
Hi Guys
NGC2035 Seagull Nebula Ha RGB : Ha 10hrs, 3 nm 20min subs bin1: RGB 10 min subs bin2
Taken on a Meade 12" LX200R OTA, G11, ST10XME, at f6.7
Well, I think it is  .
I slewed to NGC2035, and this is what I got. Doesnt come close to any NGC2035 image I googled or can see on reference sites, so I dont think it is, anyone know?, Im sure its pretty common tho..
I agonised over this for a month, it was a bietch to image in 3nm Ha, sooo dim and noisy, but what the hell, post and be dambed. I cant do better, run out of time on it, must move on  .
Lets say it has a dark medievil look to it, the sort of image youd find in a PC game  .

Although it looks a little similar to the Sea Gull I did some to time ago it sure is a heap better then mine Fred,  very nice indeed and so much detail, great work.

lovely-no stupendous- shot..maybe the issue is there are two nebulae with the monicker seagull nebula--the Northern hemisphere folk call IC2177 the seagull nebula while those who can actually see the Clouds call NGC 2032 the seagull nebula; and NGC 2035 is part of the same H alpha region?

Only one month Fred?.. bah luxury, I was still reprocessing reprocesses of my deep Cen A image 4 months after the fact before I got it right
Don't know if it is a Seagull...as there is deffinitely a crazed pink Gala screeching at me in the lower half of the nebula
Not surprised you had signal trouble on this one with a 3nm Ha filter and nearly F7 on a fairly faintish nebula like this.
A very interesting picture, nice job

Thanks guys, not the best quality but interesting swirls there.
Leon, Narayan. Yes, when I googled NGC2032 some similar pics popped up. NGC2032 and 2035 are there with some others, it turns out this is quite a wide field shot, and the seagull is there, took a while to see the shape tho.
Mike S ,The agonising was whether I should bother with it at all, it just seemed to take huge extra data for little extra value. The ADUs on 20min Ha exposures were less that 500 and buried in noise.
Ice Mike . Yes, has an interesting shape, really comes out in 3nm Ha.
Thanks Louie, glad you liked it.

Great work Fred. Quite a dim nebula. I imaged that a while ago in LRGB. It wasn't that great.

Very nice. Interesting shape. I don't think I've ever seen this object before. Must be extremely faint given the exposure time.

Nice to see some interesting and really deep space targets, whatever it is.
Did you remember how to polar align your mount when you arrived home Fred?

Pondered on this image for a while Fred. I love the details and nebulosity colour delivered by your HaRGB processing. Do however feel you could have managed the stellar profiles better. Perhaps re-layer straight RGB as colour over the top and mask it. If you are finding the RGB data isn't a match for the tight stars produced by the Ha filtered data, generate a synthetic lum from the RGB first. This will make it easier to integrate should you have issues. I was not aware of this Seagull neb, only IC2177 in which I've imaged sometime ago ( here). Names are names eh? I guess its no different to M1 and NGC6357 - both referred to as the crab nebula. Though the latter I think is more like a lobster as a tail is visible with good Ha data. Well done and thanks for sharing your efforts.

I think Ha might have helped rather than L to get some detail, but then the noise........
Thanks Alex, Marc, the interesting shape made me perserver with it  .
Deeno, Oh sheesh, Ill never live that one down  . I always stuff up polar align 1st up, so sorry, very embarising. And NO, it went totally skew wiff back home, I had the RA/DEC motor plugs in arse about for a good 2hrs, now that, can mess with your mind, totally  .
Ken Its mess, the naming thing is full of errors as ive just found.
Hehe, I was thinking more galactic sink hole (the interesting part)
Jase. The mystery is solved. According to Don Goldman, NGC2035 is wrongly labled "Sea Gull Nebula" in Sky V6. Of all applications, youd think theye would get it right  .
As the stars looked about right, I didnt bust a gut to get them any better given the pain trying to process the rest to some acceptable standard. Im thinking I may try to get some more Ha data and clean it up given a complaint of "same-as" image posting in another thread, rather than start on another over-done classic  .

Fred,
What a ghostly object.
Great work.
