This is my second attempt at M31, this time with a focal-reduced ED80 and the Modified 350D. This was a test to see if I could run the equipment overnight while I slept. Seems to have worked pretty well, but without dithering (which I still do manually), there was a large amount of residual pattern noise after calibration, registration, and stacking. While Neat Image did a decent job of removing that pattern noise, I really need to look into something like GADfly (see the Files section of Digital_Astro) to automate inter-exposure dithering. This is the full frame, shrunk for display on the web. A higher-resolution version of this image is also available, as is my previous attempt from last year with an unmodified camera. North is right.
