Hi Robin, Fixing the drivers MaxADU return value allows the sensor analysis to run. Only one remaining issue for a complete set of information is that strange gain value. Turns out this strange gain (16777215) means set the camera ISO to Auto. I'd actually like to disable that, since it messes up th...

Hi Robin,
I think this explains it. I checked the MaxADU value myself, and it is reporting 20000. When I checked the actual code, the 20000 is hard coded. I will see if I can change the driver code, and then confirm.

Hi Robin,
What I see with SharpCap's pixel value tool is max values of 32744 for both RAW and RGB values. This is strange.

Also, the weird value for gain doesn't look like a sharpcap bug, I see the same weird value as the first gain through a diagnostic tool provided by the sony ascom driver writer.

Thanks Robin. Actually I did a check myself, by connecting to the driver through alpaca and python, and it looks like the max value for the RAW output is 16383, which means it is 14 bits. This is more than 50% of 20000, which I confirmed is the MaxADU returned by the driver. Would the debayering be ...

Thanks for the feedback. The ASCOM driver is just reporting back a fixed value (not camera dependent) of 20000 for MaxADU. Unfortunately I can't change it from the UI, since the developer hard coded it. Not sure if it is correct or not, but I will take a more detailed look at the actual data returne...

I just connected my mirrorless sony a6400 via its ascom driver, and when trying to do sensor analysis the brightness seems to clamp at 50%, and no matter what I do it will never go above this. I have attached a screenshot. Screenshot from 2022-12-02 11-38-03.png I am new to Sharpcap. Am I missing so...
