I have illustrated my problem in the picture below. After calibrating the star colors, the colors are completely desaturated and the picture gets a greenish tint.
As you can see in the example picture the colors look much better before the calibration. Do you have an idea what went wrong?
Is it possible to skip the "calibrate star color" step?
I have loaded the stack into a drive folder for you. You can try it yourself 🙂
There is a small shift ( i think du the Optolong filter) to the green side, if you open the star calibration tool you need to move the Magenta / green constant slider to the - this will move the green cast to the magenta side ( from green to white).
See screenshot for the settings i used.
I did make in a few minutes this version of you're data, maybe a bit to the red / magenta side but i did it on a small laptop screen.

An alternative method is to apply HSL selective color after calibrate star colors. In you case, I try remove cyan from green, reduce cyan in yellow, remove red and yellow from cyan, and increase magenta in red. Just play around with these colors!
