NGC 2683 (The UFO Galaxy)

[Shibby]

It took me several nights to pull together enough data for this one. I've still had to push the luminance quite hard to reveal the fainter parts, but a fresh set of flats helped a lot. I'm a little disappointed I haven't revealed a bit more structure in the outer arms.

I went looking for interesting facts about this galaxy. Couldn't really find any so here a couple of mildly notable facts

• It is not part of a group, which is relatively uncommon.
• It has an unsually high number of globular clusters - 300 or so.
• Although arguably flying, it's not unidentified. It was discovered by Herschel in 1788, although of course nobody knew what "spiral nebulae" were for sure until Hubble figured it out in the 1920s!

Image details

• 190MN
• Atik 460ex
• L: 22x600s
• RGB: 3x17x300s
• Total: ~8 hours
• Processing: DSS, Photoshop
• Scale ~1.4 arcsec/pixel

Thanks for looking

Great capture with the MN190 and Atik 460 combination, lots of tiny galaxies in the image.

Excellent! Once again, a 190MN delivers.

I've imaged this galaxy three times now, and haven't been able to extract more detail. If you stretch the data very aggressively, you find out that the galaxy extends a little further, but not much, and no additional details. So, well done.

Thanks very much! Yeah I've been very happy with the 190MN ever since I got it. It's difficult to imagine ever swapping it for anything else (unless I come across a massive windfall!) I decided to re-collimate it recently, though, using an OCAL and think I've had a negative effect. I'll post a separate thread about that.

Collimating this scope is tricky. Maybe this old thread is of interest to you.

Nice image. Its the same scope and camera combination I am using and i am also very happy with it.
