This was a project from over a month ago during a mistake I made on it several times with flat calibrations. 

Anyways, the Nikon 180mm at F3.6 (49mm step down ring), is pretty fast and gives quite a wide field of view. And I cannot complain about the ED glass of course cool.gif

Shot with Nikon D5100, 21x90s, dark and flat calibrated

Nice image! Sure, the super up close Galaxy images are really cool, but I think the widefield images like this give you some perspective.

Is the focus off just a hair? The stars look a little big and some show CA (maybe some of it is compression) but I would be very happy if I took this.

Compression did degrade the image a bit yes. However, you got me at the focus, it is off just by a hair bigblush.gif

Am I seeing traces of IFN in the image, or is it just my averted imagination?
