I have the ZWO ASI678MC and I’m trying to pair it with the C8 Edge HD. How do you focus this camera? I was told that you didn’t need to worry about back focus distance. I tried using the ASIAir plus and the computer or studio. I don’t have the EAF yet due to back orders so I’m just turning the focus nob on the back of the SCT. Can any tell me what I’m doing wrong? Do you need the night sky or real stars or the moon to put it in focus?
