I havent tried this yet but i stumbled across it while researching what to do for meteor impact monitoring on the moon
http://www.lunarimpacts.com/nudger.htm
"an application that can be used to auto-guide an ASCOM driven telescope, by tracking brighter objects on the earth-shine illuminated shadowed surface of the moon. It removes the need to constantly make pointing adjustments using the hand controller.
It is call it "Nudger, The Lunar Auto-Guider" because it nudges the telescope ever so slightly when needed to maintain accurate pointing. It is intended to be used by individuals or groups that monitor the moon for meteoroid impacts.
