There is a "tilt-up limit" in ACP, but to be truly safe the limits should be sea in TheSky for the Paramount also!

ACP cannot work with MaxIm autofocus. Post a request for help in the FocusMax forum here, or even better in the FMax_UG group on Yahoo!. Before that, however, you'll really need the latest version of FocusMax ( that you get from the FMax_UG group in its files section. There have been fixes for Vista/Win7 in these later editions of FocusMax.

ASCOM 6 is definitely NOT the problem!
