I just got the new ASI294mm mono camera and ran the sensor test.
The gain/eADU numbers look way off. If I divide by 64, they look right. (camera is 14-bit so divide by 2^6 if it thinks it is 8-bit?)
I saw an earlier thread about ASI drivers reporting the wrong bit-depth and I could not find a place to change it manually so I assume this is a bug?
lmk if there is other detail/info you need (or if this is actually operator error).
FWIW, here is the output from the test:

Re: Sensor test reporting 8-bit on ASI294mm (mono)
Hi Ryan,
my first guess is that you ran the analysis with the camera set to 8 bit mode (MONO8 in the colour space option). Hopefully if you change this option to MONO14/MONO16 (not quite sure which it is for that model) then you should get the correct results.

Lol, someone else just pointed that out to me.
I must have been sleepy as I did not see that setting.
I'll give that a shot tonight. Thanks!

For what it's worth I got this for Mono16:

@donboy, what do you use as your offset?

I believe SC set it to 8 for the analysis. I normally don't use an offset with my cameras. I believe that the ascom driver sets offset to 30.

Hi Ryan,
those figures look reasonable – I wouldn't expect them to be very different from the values that get produced for the colour version of this sensor.
SharpCap will adjust the offset/brightness/black level controls during the analysis process to ensure that the values are high enough to separate the histogram peak from zero point when taking measurements.
