Hi, can anyone point me to a tutorial on how to add Ha to an RGB image in Photoshop? It seems like it should be obvious, but for whatever reason I am struggling to do so...thanks in advance 
Ed

I think one way to do it is to combine the starless H-a with the red channel using superimposition or stacking. I'm a newbie here too, so don't take it as a fact.

One method is to add Ha as a luminance layer:
- Mode: Lighten
- Opacity: 85%
- Fill: 50%

You can also use Siril (it's free) to combine Ha & RGB using PixelMath:
