@Allan: one sub of 5 min give me a background of 4500 ADU in L, i cannot ask more to my sky in my experience. I decided to go for a lot of 5 min sub. One sub show just vdb 7, 8 and the stars ... i asked from myself if continue or not. 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.
Great field Leo I understood from you blog you were forced to have some "rest", this one means you are fully back in the game? Hope so!

Hello Marco, thank you for reading my blog! Unfortunately there is no cure and therefore any therapy attempt , i do a "lap on track" to see if it works. At that time I did 2 photos ... the next who knows!
@Allan: this is one of the reason i switch to QSI ..
