Rotator angle changing with each filter change

[Larry Groom]

Hi all,

Here is a log of a RGB run from a few nights ago, and I noticed during the run that the Pyxis rotator was moving alot. Looking at the images after, it's obvious that the PA after each fiter change was different. It looks like after a Plate Solve that ACP is determing a differnet PA and changing it back to the planned PA of 30. (It looks to me that the rotator would be turned to PA 30 but the mechanical position is different each time the rotator is moved)

Thanks

Larry
