It's finally time to start using the ZWO ASI294MM camera I bought several months ago. I've been waiting for nebula season so that I can get better resolution out of my William Optics Redcat 51 and GT 81 with smaller Bin-1 pixels of the 294MM. Bin-2 mode is a great match with a long focal length telescope, like an SCT. We review the specs for ASI294MM and compare them to the ZWO ASI1600MM I've been using.
