Out again tonight and had a lot of success. Although my images still are not showing totally flat, I think they're manageable for the time being. I've spent tonight just working on collecting L subs for M101, which I hope to be able to add more L and some RGB to tomorrow night.
I spent a little time experimenting with CCDAutopilot tonight, and I have to say, I like it. I did all of my imaging with it tonight, and figured out how to set up a session, have it auto focus after a set period of time, and even calculate my filter offsets. It seems to work quite well, and I think I'll be using it fairly often, given my need to refocus frequently. If I can get it handling my imaging sessions for me, including dealing with meridian flips, I'll be pretty much set to go. Once I'm comfortable with it slewing unattended all night, I'll take a look at it's automated parking and shutdown.
All-in-all, another great night.. although, I do see some clouds going over now... darn.. that'll screw up the offset calibration!
