Hi Adam

I followed your suggested method of blending in the Ha data into the red channel and I was impressed by the result.  

I was wondering if you would recommend this approach for blending the Ha data into the Lum channel  eg follow your approach but replace the red with the Lum channel ?

I tried it on some of my own data  and it seemed to improve the overall result eg it brightened the blended Ha data.

Sure.

"Image"Blend.... image can be any. :)

If you are doing LRGB and you add Ha to the  Lum channel- then you also likely want to add it to the  Red channel so it is colorized properly. This is  the typical way.
