The thing to bear in mind is that the rotator angle that’s reported by the rotator is relative to an arbitrary position and relating this to the position angle requires that a calibration is done in SGP. This calibration generates a Sync offset.
The initial angle required is 271 and no calibration is done so the sync offset is zero. The rotator sets that angle and an image is collected and solved. The solved angle is 0.32 degrees so the sync offset is actually -270.6765.
After that this offset is used to convert between position angle and rotator angle.
The $64K question is do you end up with the image at the correct orientation?
If not then what’s needed is both an SGP log AND a NiteCrawler log covering the same sequence. Details of the position angle that’s requested and what you get may also be needed. This information will give people a chance to work out what’s happening.
Angles are tricky because they wrap round 0 - 360 or 180 -180., 271 and -89 are the same angle. It’s very easy for there to be confusion about this.
