Description

Just 52 out of 100 quick light frames (10sec each at ISO1600) without calibration under passing clouds. Wondering why the stars in the right half of the image are trailing, most prominently in the 2nd quadrant (top right). A tilt of the optical axis would result in poor focus, in that I believe it is a tracking issue. My mount has quiet a few :-) Hints are welcome.
