CLS CCD filter - color correction in Siril

Software Siril
1

I have a custom white balance in camera - but that only applys to .jpgs the camera creates, and the liveview viewfinder - it is not used with RAW files - Canon .CR2 format.

Does anyone have experience with using this filter ? If so - how do you correct the colors?

White balance is just one exif parameters not relevant in astrophotography. At least at preprocessing stage.

You need to use color calibration tool provided by Siril after stacking.
