This was an issue in the QHY ASCOM driver. The latest version fixes this.


I have downloaded the latest version of the allin one for the qhy 268 m it is still the same unless i am missing something


Not sure which one you are referencing but go to the QHY download page:


and get the file called: Beta Ver. 2023.2.28

When installing there are a lot options including two kinds of filter wheels.

I have a QHY268M with a QHYCFW3-M-SR5 connected via the camera to filter wheel cable and it works properly. Make sure you use the ASCOM setup to configure the filter wheel for 7 positions – the factory default is 29 positions!


I reported the same issue , only seemed to affect SGP and ASCOM driver. I had to reinstall the driver to get it working again. Happened twice, can’t work out why one day it works fine and next day only 5 filters showing.

I also found my QHY600 temperature incorrectly reported, not sure if connected, but when set to cool to -10c it would show things like Cooling -13/-10 for a few minutes then work correctly.
