I know that PEMPro 3 clearly states to not connect the mount (AP Mach1 in my case) to any hub while using to update PEC. Problem is that strictly speaking I could not do that remotely - I'd need to sit in the dome and watch and slave it myself. Best solution I have thought of would be to mount the little observatory web cam on the OTA itself and watch. Connect to dome, only with POTH, and just move it from time to time. I thought this group might have experience with this step. Any thoughts appreciated.
