Brett, yep, HC meant Hand Controller. Adam mentioned the NINA Primary and Secondary speeds settings in the NINA Telescope options, mine only allows 3 or less, and the error message complains that 3 is not enough! It was about that time I decided not to bother further. I tend to agree with Adam that the ASCOM interface is probably the culprit.
Since my mount PC is in the obs on the mount, I don't have your problem of running back and forth, which would be a PITA, especially like last night when it was -2c at 1am, when I stopped imaging and went out to close the obs roof. Much nicer inside with the wood fire and Remote Desktop.
I'm too much past my use-by date to bother getting into the Discord scene, so I tend to miss out on all that discussion. My bad. Tried it once with a different group, but the reception I got when joining was less than enjoyable so decided not to bother again. Between FB and IIS, I really don't need a bunch of Discord messages as well.
