We have never seen any issues controlling the QHY10 TEC. Please make sure your drivers are up to date (both native and ASCOM).
If you are still having issues, please see our help thread here and we’ll see what we can find:
This is something SGPro does not control. We read and display data from the camera exactly as it is delivered to us by the ASCOM driver. Of all the ASCOM camera drivers available (even other QHY ones), the QHY10 is the only one that chose a portrait display. If you want this to use landscape, you should bring this up with QHY.
