I am having different edge performance when I rotate the camera in the focuser.
Newtoniano GSO 200mmf4
ASI 1600MM Cool
Notice that A is worst
B is a bit better (rotated 180 degree from A)
C is the best (rotated 90 degree from A)
What may be causing it? sensor tilt?
The images bellow are in the order: B, A and C.
