can som ebody please tell me what I might have set incorrectly if a result with a green cast comes out after integration? Also the stars seem to be greenish. And is there a setting so that the stars are not so bloated?

I used a Narroband filter for recording with a color camera. Can this come from the filter?

Thank you!

Did you use proper calibration data (darks, flats)? That might help as I think it's probably regular vignetting. Good calibration will also help in correcting the data better. Like using light pollution correction (tab 9) helps with this as well. You did follow a workflow like in the workflow section for Optolong narrowband combination?
