I have recently gotten back to ccd imaging with a newer setup. For years I was imaing with a Cookbook camera and a 16' Newtonian. I got so-so results using...

I was pretty envious of that 16' Newt myself. <G> The lower left of the image isn't background; there's nebulosity there (and almost everywhere else, too)....
Thanks for the reply Ron. I knew there was nebulosity there, I was just afraid the color balance was way off due to my being chrominance- challenged so to...
C/2007 N3 Lunin is a magnitude 11.8 comet in Sagittarius. I imaged it four days ago under poor conditions so I tried again last night. I was able to make only...

Hi, As I improved my processing with time, I have now encountered a problem which is really trying me out. That of bloated stars. This problem is spoiling good...
