A friend of mine uses APT. When he PlateSolves, the rotation angle is somehow sent to Stellarium. So when showing the rectangular camera field of view in Stellarium you can easily see how much to manually rotate the camera to get the ideal camera orientation.
With SGP the PlateSolve and Center of course gets me perfectly centered on my target. But I kind of have to guess how much to manually rotate the camera by looking at my SGP image and Stellarium.
It would be great if changes to rotation as picked up by the PlateSolve would be reflected in the orientation of the camera FOV rectangle in Stellarium.
