Some of the "easy" things in the sky are always tempting to try again and again. I shot this image of M27 about a week ago. Basically, the only thing I did different was a much longer exposure. Took my chances, and tried to put a little more trust and confidence in my autoguiding system. I took a few 10 minute exposures to see if I could get in deeper to this object. Seemed to work! You can see a little more faint details around the edges of the nebula. Guiding errors aren't to bad either. The Starshoot camera and PHD Guider are working pretty well now.
I'm sure I could process this better if I could remember some of the methods that Adam Black taught me when I was at Mt. Lemmon last December. Pretty happy with the results otherwise!
This is 6 exposures at 10 minutes each, ISO800 and the 12" telescope at f/6.3.
