Should all ZWO cameras have the same thread orientation from the factory?
When I attach the cameras to my filter wheel, the 1600Mpro is right side up. When I attach the 183pro the camera orientation is up side down. I have to use a 0.32mm T2 shim between the 183 and FW to correct this, but causes back focus issues from my scope flattner. It seems as if the 183 camera face plate orientation is 180 deg off. I did have the 183 camera repaired by ZWO, so perhaps this is why? I often swap cameras between imaging sessions, so having bad camera orientation is problematical.
