 Now that I have a good polar alignment technique down with the CGEM and decent guiding using Backyard EOS for acquisition and the SSAG and PHD on the Astrophysics guide scope, I am experimenting with prime focus photography on the 9.25" Edge SCT. Last night I had my first decent success. I took 10 subs of 4 minutes duration each at ISO 1600 of the Pacman Nebula and the Pleiades. The results posted here are what I got after using Deep Sky Stacker and Photoshop CS2 for processing. I could tell both from the histogram and the final images that shooting at f/10 could benefit from more exposure time. I might try 6 - 10 minute exposures the next opportunity I get with a moonless night and still air like I had last evening.
