Description

I've been trying to get my AT8RC back into collimation after I cleaned the mirror, and it has been a struggle to say the least. I've been taking exposures of M 92 to monitor my progress, and last night's subs were at least close to good enough to produce an image. I've got a little ways to go collimation wise, but I'm close. Globs are tough for me as well - any tracking issues, focus problems, etc...become quite evident, not to mention how difficult I find them to process.
