I re-processed the L channel and added that to the narrow band data from last week. I think I like the details and stars a lot better. The L channel was a "luminance" on the bottom, and I used a 40% "multiply" with the narrow band between the L and the "color" channel on top.

Hello Charles,

I once asked a similar question to Richard Crisp and he thinks that adding a proper luminance layer to narrowband images makes a lot more sense than using the H-alpha channel as luminance as most people do.
I think it came out really good!

Ciao Charles

Luca
