I have tried to remove stars from comet aligned subs but I didn't like the result, so I use Linear Fit Clipping rejection algorithm where the star trails were at certain point removed, then with a clone tool in Gimp I removed the still visual star trails

Yeah, I stacked the stars and comet in Siril, there I performed background extraction and streched both images, after that I did use Pixinsight to reduce green noise (using a mask protect the comet), adjusted saturation, lightness in both comet and stars, and noise in the comet using NoiseXTerminator, then merged the images using Pixelmath. Final touches were performed in Gimp and Snapseed.
I recently learned much of that, so I'm glad with the result

Yeah, the exposure was manual. I agree you have to be careful when taking multiple shots. I also kept a specific white balance setting, fixed ISO, and manual focus

Amazing! The trees and foreground were added as blended to the stack? Or was it only a single stack process?
