I have the Gemini G53F mount, and it does have an ascom driver in fact 2. (but one reports wrong time to meridian and does not report in a reliable way end of slew)
The issue I have is that the reliable one that reports in a reliable way end of slew, reports time to meridian correct as long as you don’t check the auto meridian flip feature …
As soon as you check this feature time disappears and also when you start an image run SGP reports the mount does not support flip and deactivates it. The driver indeed does not support side of pier … but apparently this seems no issue as that works in ACP according to the vendor.
So could there be an option to just take the reported time to meridian that seems correct and go with that?
I use the latest official release … but same issue was present with 2.3
