M31

I thought I'd try to improve on my M31 shot taken a few years ago with the William Optics Zenithstar 66 which is not a very flat field so it needed cropped a bit too tight. The framing worked out great with the AT65EDQ and although there are pros and cons to this image over the other one, I think I'm really pleased with the result here.
