All in all, you've picked up some nice details to the main object.
I do see some coma radiating out to the corners.... what corrector are you using and have you checked the spacing from it to the CCD/ window?
Thanks Rich. Yeah I need definitely more data on this one. Coma's a bugger. I have a MPCC but no real way to modify the spacing. I've always had this problem and I'm not sure how to resolve it. The spacer doesn't allow to shift back and forth even a couple of mills. It's one solid piece of aluminum I was thinking at one stage to make a spacer that I could shorten like a helicoidal focuser but I haven't found anything anywhere ressembling it.
