Oh, I must mention collimation here. I spend a lot of time doing this lately. The C11 has held wonderfully the last few years but lately every time I look, it's been out a tad, so I suspect something going on/wrong in the secondary holder somewhere..
Anyway the point is, that MUST be on the money before any fine features can hope to be captured, especially in less than nice seeing. I always collimate on the nearest brightest star closest to my target. I always use the camera to collimate with, at my image scale I'm going to be working the target at.
