I am sure this has been discussed before and I am sorry for revisiting, of course none of the topics are exact to my situation so it "feels different"... I have done alot of trouble shooting but continue to fight this issue.
I have a TPO 8 in RC scope, and an ASI1600mm PRO CCD - I am fairly sure I am in good back focus at 250mm for the scope as well I have "day tested" and get reasonable focus on trees about 8 blocks away...
I cannot get ASI studio or APT or any other planetary imaging software to focus at night, it is either black or full of "blinking fake stars" - my guide scope a blue one from Astromania "SGCMOS Series Telescope CMOS Camera" - I ordered an ASI because it will not seem to work with my ASI Pro.... anyways neither scope will "focus" at night... I have tried many settings of course and about 2 hours of changing back focus and rolling focus back and forth to find focus with no luck... can you all please suggest some things please?
