As it's Christmas bonus time, I decided to replace last years bonus purchase, my ASI294MC Pro with the new and apparently quite excellent QHY268C.
I'm a little confused about the backspacing though. I believe the camera itself is 17.5mm, and the required dovetail to M54 adapter being 6mm? So for a scope requiring 55mm that would be I need to find 31.5mm of spacers?
Any tips on the imaging modes? Anything else to be aware of?
