So not having used my gear for about 4 months, and having the guts of my QHY10 replaced, it arrived in the mail yesterday, and it was clear enough to do a quick test. So far so good! No strange shadows in my images, and they look a lot cleaner as well.
Finally worked out the collimation on the RC, guiding and tracking were beautifully smooth for a change. Even under a nearly full moon, I think this is a pretty good start.
6 x 5 minute subs at -20 Degrees with no calibration frames.
Hope you like it
Erik.
