When I use the LEGACY version of the Polar Alignment routine, EKOS will start a photo capture without waiting for a delay after slewing. The result is blurred images that it then tries to identify with asymmetry. I set the delay time, and that works in regular alignment mode, but not in the Polar Alignment mode (the legacy version, I can't use the new version at the Equator).
I can confirm Peter's problem. During my latest session I ran the legacy polar alignment procedure and ended up with a picture that did show star trails.
