Excellent. I assume the changes are made to the stable build, yes?
And the only thing have to be updated is indi-qhy is that correct?

It is not "turn off" per se but some what reduced to a more manageable level. Infact I find the 294c calibrate the dark quite well, there are little to no residual amp glow after calibrating dark frames with master dark. But less amp glow always a welcome feature.
As for the changes Jasem incorporated, I'll test them out and report back today.
You can sort of (save) the default ISO by setting it to 1600 in the device manage and go into options tabe and save the setting. Next time you connect the device it will use the iso 1600 instead of 0. Also 1600 is not the "best" ISO. It simply the unity gain where you get the ADU =1 and on the particular qhy294c sensor ISO 1600 enables the High Gain mode which make the read noise extremely low (-1e) according to QHY's specs. I find that the High gain actually not enable at 1600 but a dozen of ISO value later so setting it on 1650 or so would be a good idea. But from 1600, dual amplifier also introduce more amp glow which I am hoping it can be manage with the enable of amp glow circuit on this update.

Only on cameras that have the amp glow circuit. You can read on QHY website specs to see if yours are supported.

I'm using Kubuntu 20.04.

Is the amp control perhaps on the Image Settings tab?

So to avoid the libraw20 vs libraw19 conflicts-and-dependencies palaver, I opted to just install the newest indi-qhy and libqhy from the nightlies while leaving KStars as the stable version.

And...

I now get an INDI driver crash when starting Ekos.

So after that brief foray, I've had to return to using the old indi-qhy from stable.
