Good night:
I have a serious issue with QHY6 driver.
I use the càmera as autoguider and there is no problem with the first batch of images but when I have more than one scheduled in Ekos then driver hangs and the next batch does not start because of lack of guiding. The only way for QHY6 to be working again is to take power off and put it back on.

I use KStars 3.5.6 Stable running on Linux Mint 19.3 Cinnamon (Cinnamon version 4.4.8) Linux kernel 5.4.0-91-generic.

I don't feel like replacing the autoguider CCD, it works fine autoguiding so any suggestion will be very appreciated.

Thanks in advance
