i haven't been looking around here, but that is just because I have been mostly happy with my AP game and I didn't have to troubleshoot for some time. However, now that Orion is up, I am actually suffering from too bright stars. I get column errors and my idea was to average them out by rotating the camera. This is the my starting point:
But rotating did only add more of those nasty defects. I used Windsorized sigma clipping in PI (left) and kappa-sigma in DSS (right).
The version from DSS looks way better. I played with the rejection values in PI but to now avail. What does DSS do different?! Thanks
