My fov position angle is 55 degrees
In sequence configuration should I use Rotator PA or Sky PA (Rotator section) ?
What is on the sky is SKY PA, what is mechanical is Rotator PA.
Sky PA is something you can obtains only plate solving the image and its related to image rotation/orientation in the sky , Rotator PA is a mechanical value of rotation of your rotator and is something you can decide how you want.
A planetarium represent the Sky so its a SKY PA.
All the best
Thanks a lot Leo !!!
