bschnitzer FWIW, it doesn't have any way to do horizontal calibration in sun/moon mode (because that relies on plate solving and stars may not be visible). It needs the compass calibrated, and then the scope to be set level (ideally within .1 degrees). It then raises itself to the appropriate altitude angle pointing 15-20 degrees (as far as it knows) to one side, and then scans horizontally until it sees a little light on any edge of the frame, and moves toward the light until it finds sun or moon.. What I usually see is it initially points to the right of the moon, and searches left.
I'm used to calibrating the compass on mobile devices by just moving it all around in all axes (tumbling). What I found when I tested this last, was the Seestar doesn't like that. It shows an image of itself being rotated only around the vertical axis, and it appears to want only that. If the calibration progress bar gets stuck, just keep turning it carefully around the Z axis until it eventually succeeds. When I did a tumbling calibration, the progress bar completed very quickly but then it had no idea where to point. Was literally looking for the moon 90 degrees off.
