I have been using PlateSolve2 for a while without major issues but last night I ran into something I have never experienced before. After solving the frame, PlateSolve2 was not able to move the mount to the precise DSO location. PS2 would solve and then SGP would tell me the mount had slewed, take another test shot (which was identical to the previous) and solve again and again tell me the mount slew, take another test shot without moving the mount by a single pixel.
The mount slew no problem to the area but would not center with SGP/PlateSove2 combo. I could move the mount “manually” through SGP.
I am a bit at a lost as to where the problem could be from.
