ngc 2683, a galaxy in Lynx

[wimvb]

Ngc 2683 is a type SAb galaxy in the constellation Lynx (RA: 8h 52m, DEC: 33 deg 25 min). It is at a distance of about 25 - 30 Mly from the Milky Way, and has an apparent magnitude of 10.6. Its diameter is approximately 87000 lightyears, making it smaller than our own Milky Way. From earth, its size is 9.3' x 2.2'. It is uncertain wether this galaxy has a central bar.

We see the galaxy almost edge on (78 degrees inclination), and the dust lanes give the center of the galaxy it's yellowish colour. Ngc 2683 contains a large number of globular clusters.

why isn't "U-F-O" accepted in the title?

Lovely image Wim with excellent detail, colour and stars.  A great first light for your new observatory.

Thanks, Dave. As it turns out, I have now imaged this galaxy on three different occasions; once with my 150PDS, once with the MN190 from a roll off shed, and now from my obsy. The latest version shows that gathering a lot of data is the way to go. It allows for better processing. And my new obsy makes this possible. I would never have been able to collect almost 12 hours of data on just two nights without it.
