Quote:my experience with ASPA is that drift alignment is still superior.i guess if you use widely-spaced stars ASPA would be more accurate, but i don't get to use widely-spaced stars most of the time.beckemd - ASPA is only for celestron Nexstar and Nexstar+ hand controllers. it is basically an assisted polar alignment routine (like Alignmaster) but fully self-contained in the handset.i understand that the latest Synscan firmware also has a similar feature - though called something else.
Quote:Not sure what you mean by "widely spaced stars". ASPA only uses ONE star.

Quote:Personally I wouldn't waste time imaging with C9.25 on CGEM. Sorry if that sounds too harsh. But if for some reason I do, I would at least use OAG instead of guiding scope. IMHO
