I have tried everything possible to get SG Pro to connect to my Celestron AVX mount, to no avail. My PC is running Win 10 Pro, with the Nexstar HC connected to my PC via a USB 2 cable. I have installed ASCOM 6.4.1 with the Celestron Unified Ascom driver. I am using the latest version of SG Pro, although still in trial mode with valid days remaining. I have confirmed my USB connection is correctly recognized as COM10 by SG Pro, and Stellarium connected with no issues whatsoever (via COM10) and could slew my mount.
In SG Pro, I have tried using both the “Celestron Telescope Driver” option as well as the “Generic Hub” option with Celestron set in the ASCOM settings; neither work. No matter what I try, including enabling “Minimal Mode,” I get the same “Error connecting…” message. I ensured the mount is aligned properly before connecting the USB cable, in case the mount’s startup state had anything to do with it. I’m pretty sure the issue is somewhere with the ASCOM driver, since it fails when I test the connection with ASCOM Diagnostics as well.
I have included the 6 different log files which were generated on my last failed connection attempt via SG Pro:
Any help debugging this will be HUGELY appreciated, as I am at my wits end
