M81, M82 (highlighting regions with Ha, processing with subtraction (Ha - R))

Added data in Ha, captured with a ZWO ASI 183 MM camera and combined with last year's material that was shot with a color ZWO ASI 183 MC. After all, with the light pollution as it is now, narrowband imaging gives at least some result. Used pixel math in Siril to add the narrowband H-alpha (Ha) data to the broadband RGB image.
