Description

My version of The Cave Nebula in HSO.

Red channel = Have 100%

Green channel = S2 (50%) O3 (50%)

Blue channel = O3 (50%) S2 (50%)

After the filter combination, I ran StarNet on the color image and a some noise reduction on the Ha image and combined these with the Ha as Luminance.

In PS I colored some of the stars as these have no color at all from the Ha picture.

I hope you appreciate the result.

Thanks for looking.
