When PHD2 is connected to my SSAG with the lens covered, the viewed image looks like a grey piece of woven material rather than totally black.
I have reduced the camera gain to 1, and exposure time to the minimum 0.01 sec. I have also assembled and use a file of dark frames.
I see this behaviour with the both versions 2.3.1 and the latest vers. 2.5 of PHD.
Have I forgotten to do something or is this normal behaviour?
