Shot this during the absurd early January 2010 cold spell. Used a friend's 4 inch f/5 Celestron refractor, this is a stack of 90 second unguided exposures, total exposure time was a bit over an hour. The scope is an non-ED/APO and has some noticeable CA, I used the Photoshop clone tool to clean up some of the more egregious purple fringes. All in all I was pretty happy to be able to get this from my light polluted back yard. Quite a change from my earlier attempts http://www.pbase.com/image/24389062
