This is truly great tutorial!

The best video on pixel math on RUclips that I have found. With all this information cloudy rainy windy nights mean nothing. You are the rock star for us.

Nice experiment with colors

Very helpful Craig! Good approach not just to show, how it works but also and especially how it NOT works. Thanks for sharing this. Clear skies

Awesome

Thanks for the nice video. I do have the raw data for this nebula and will try your method. Beautiful colours 👍🏼👍🏼.

Another excellent video Craig. I could not help but notice the similarities between this process & using a channel mixer in PS or GIMP. I'm working on a hybrid method using the stretch techniques in your other osc to sho vids and this for color balance, particularly adding red to green. Your processes have opened doors for me, my thanks.

Many thanks, very helpful tutorial - that's the trouble with processing, we are never fully satisfied :)

Thank you very much! Very interesting video! I’ll try it and see what can I get 😄

Great vid, very interesting. Did you use a dual or triband filter when you took the shot?

L-eXtreme dual band filter.
