Hello Ivan! It sounds like you are making progress.

ACP does not have an "automatic guide star chooser" for a system with a rotator. This is not my lack of imagination, it is just a nearly impossible problem. The astronomer must choose how to simultaneously place his target in the main field while rotating and positioning to "get" a guide star. Please see ACP Help for details. I don't expect everyone to read all of the docs, so I am posting this as a guide to get to the information. Also see the videos below:
