It appears as if the latest version (Skysensor 2000) of the Skysensor telescope drive comes with the ability to track satellites built in. The following message from a user appeared in sci.astro.amateur, as recovered from DejaNews: http://xp10.dejanews.com/getdoc.xp?recnum=14591986&server=db97p4x&CONTEXT=877722886.1078526719&hitnum=0 And a bit of sleuthery led to this page describing the system: http://www.astromedia.se/vixen/skysensor_eng.html FWIW, this somewhat interesting item on amateur adaptive optics fell out along the way: http://voltaire.csun.edu/ao.html
