Core of the Andromeda Galaxy, M31

Captured in my back yard, in the white-hot light pollution zone with no filter, it's gratifying to see that anything interesting can be photographed from there with this magnificent telescope. This is not quite first light with my new Celestron EdgeHD 11 inch, as I made some test shots on star fields earlier, but it's the first image worth putting up. I haven't yet obtained any flat-field images so there is rather strong vignetting here. I am restricted to short exposures until I determine how to autoguide the mount with this scope on - my understanding is that it approaches the limit for guiding with a side-by-side setup, I have all my fingers and toes crossed.

My back yard; October 27, 2010, 8:45-10 PM; temperature unrecorded but <0 C; Hutech-modified Canon 50D on Celestron Edge HD 11 inch; unfiltered; seeing unknown and probably irrelevant; unguided; 8x100 seconds.
