Collimation of the scope is very good, but not perfect and I think I was very close on focus. I took a number of avi's with Sharp Cap most were five minutes with one longer and two shorter. Unexpectedly (at least for me) the one that came out the best was one of the shorter captures. I had to cut it short (3-4 minutes), because Saturn was about to drift out of the FOV. This is odd, because my CG-5 had been tracking well. I was easily getting five minutes with Saturn barely moving. Then for some reason, I started to get some drift.
Anyway, here is the image. I stacked it in Registax and adjusted the Wavelets, but really I don't know what I am doing. Any advice for capture settings in SharpCap or post-stack image processing tricks that may brighten up or sharpen this image?
