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.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.
