Description

This was an experiment of sorts. I wanted to see if I could combine Lum data from my C11/1600MM with RGB data shot with my MN190 and ASI294MC-Pro. I shot the MN190 version on M101 last year, and was never that happy with it as it just didn't have much detail.

The seeing was on the good side last night, and the Lum data I shot had much better fine detail. I binned it 2x2 as that gave a very close match to the image scale of the existing RGB data. The result of the combination exceeded my expectations.
