Jonathan and Paul Kanevsky,?
Thank you for responding.? I hate to think my polar alignment is bad.? I spent a long time over two nights doing an old school drift alignment.? It takes five minutes for a star to drift off my reticle line.? However, I'll check it again.
My ASCOM driver was set up to use BOTH Precision Pulse Guide and Asynchronous Pulse Guide.? I've deselected the former and re-saved my settings/ profile.? I hope I remember to double check that the next time I go to my observatory.
FWIW, I received a suggestion that polar alignment might be a problem from a member of the MI-250 forum.? He also suggested the L4 EEPROM is the best version to use; mine's already been updated.??
