Same here when being BELOW Polaris. Mount/driver crashes! Bummer!
On the other hand, when using the Mount Control from KStars/EKOS, the mount crosses the northern meridian (now above Polaris) without any issues in both directions. No crashes nor interruptions. But the behaviour of the arrow key is inverted! Meaning, I can use and hold the left button to cross the northern meridian, when I let go and press again the same direction button, the mount slews in the opposite direction, that is towards the meridian again. Very weird. Not sure if this is a feature or a bug ?!
I am using KStars (v3.5.9) from my MacBookPro and connect to the indiserver of the StarGO2 remotely.
BTW, note, that I have selected LX200 Classic... but once EKOS makes the connection to the indiserver on the StarGO2, it uses the native stargo2-telescope driver!
Enabling and disabling "Reverse Up/Down" or "Reverse Left/Right" has no effect on the arrow buttons in the Mount Control interface! The mount always moves in the same direction with the exact same status messages.
