I think QSI is a great camera but a bigger size pixel help so much in this kind of subjects (think to 9 micron pixel). I don't know the size of OAG's mirror but i haven't problems at F3.6 with shadow. Nothing is visible on flat, but i use the 2.156" adpater instead of T2. For the colour i use only bin1 for fast scope and refractor.

Thanks Leonardo for your reply.
I wish all cameras/filter wheels had there own built in OAG mirror.
It's working so well.

cheers
Allan
