To be honest I’m not quite sure where to post this question. It only indirectly involves SGP but I’m hoping other AP mount users can give me some direction.
I set up a new to me Mach1GTO CP3. I use Stellarium for a planetarium. Plate solving within SGP works perfectly and lands the target within a few pixels on the first try. Solve and Sync the mount likewise syncs the mount.
The question involves Stellarium. If I slew to a star from Stellarium the star always lands just west of center. Like every time. Here’s a screenshot of Betelgeuse:
The location of Betelgeuse is exactly where every star lands, again just west of center, when I slew from Stellarium. Plate solving within SGP lands targets dead center.
Any ideas why Stellarium points it off to the west? Could it be a J2000/JNOW issue? I believe I have everything set to J2000.
