Hello,
My setup is rPI4 / 8GB / Stellarmate OS / ZWO 183MC non cooled.
I recently discovered that all the darks and biases made with this setup are unuseable.
Because the driver adds wb correction, which I didn't know was possible. Red and blue values are multiplied by a certain factor.
For instance, a bias at G120 / o10 has median values of 704 for green channel, but 731 for red and 1336 for blue.
All other values are affected too : sigma, MAD, etc.
So, as I wrote before, those files are quite unuseable and hence the awful results I get in preprocessing.
This is not the camera's fault, but the driver's, as if I use another soft the darks and biases do not suffer those problems, all values are consistent
Did someone else ever faced this kind of behaviour ?
Any suggestion on how to work this around ?
Rgrds,
J.-Luc

The driver does not add anything. If you're having issues with White Balance WB, you can change them to the desired values and they should be retained in future sessions.

Hello Jasem,
I replied in the bug report.
Yes, they should be retained. I keep my fingers crossed.
Retained.

There is auto option for WB_R and WB_B you want to disable that.

It is - indeed - disabled.

If I understand this correctly, the issue keeps coming up sporadically. Set WB_R=50 and WB_B =50 and save this config. The issue has been discussed a number of times, like here indilib.org/forum/ccds-dslrs/6368-strang...stroberry.html#88361 for instance.

I did this and it seems it remains.
I write this, because I previously had to suffer saved values not being kept from session to session.
But, yes, this doesn't seem to happen anymore,

Good to hear it does work for you now!
