Is it possible for ACP to control the Maestro master and then let it natively control the slaved instance running acquisition on the second telescope.
I don't know, and I am sorry for that. I understand what you want and it makes sense. However, I am close to releasing an update to ACP and I am not in a position to look at adding such a major feature. I'm sorry. Perhaps you can find other software that can manage two imaging systems on one mount.
