Impressive, Hap. Your autoguiding software doesn't have a lot to do
but correct any errors you may have in your polar alignment.

the perturbations of the guide star caused by seeing and so theserandom
errors are etched into your PEM training along with the trueperiodic error
of the mount. PEMPRo allows you to capture date from multiplerotations of
the worm gear and creates a smoothed curve from that, thuscancelling out
the seeing induced errors (if you use lots of rotations) andtherefore only
trains in movements that counteract the true periodic error of themount. I
started with about 4.5 arc-seconds peak to peak errors and aftercapturing
10 interations of the worm gear and creating a smooth curve fromthat data,
my PE is now only about 1 arc-second peak to peak...which is to saythat it
is now within the measurable error caused by seeing.
