Btw, I tend to use 3-star align because I'm fairly certain the puck of the mount doesn't hold my scope square with the axes, but maybe that's my undoing too
There seems to be an art to the alignment star choosing, but I usually aim for 3 stars in a wonky triangle...so 90-120 degrees apart and with at least a 30 degree difference in Dec between the first two. It's not always easy, at least for a northerner, to identify some of the stars the handset suggests.
