Is it possible to create a plan that I can also set up a rotation before it starts? I've shot the Iris nebula, but wanted to create a plan for M45. But I need to change the rotation. I can rotate the target box in skyatlas, but the plan doesn't save this rotation.
Unless you have an automatic rotator - you will need to do the rotation manually. The plan feature is meant for unattended imaging.
There is a rotation assistant included in v2.0 (personally I have never used it) which can help with achieving the same rotation angle.
