Welcome,
Voyager doesn’t manage manual rotator. Was born to manage unattended imaging.
Some users asked this, we put in the todo-list. For now if you need you can use ONTHEFLY section. Solve the start image and retrieve PA with one of the buttons “Plate/Blind/Astrometry.net solving FIT File”. After you can use “Plate solving actual coord” action button and check the PA when you rotating the camera.
Please take care that some instruments if you rotating camera lost collimation or introduce a big tilting. My experience say to dont do this if its possible.
All the best
LO
