What is a good formula in Pixelmath to blend Ha into RGB and Oiii into RGB? This is mono processing if it helps.
Blending in Pixelmath
one way is to make H and O into HOO
then do a 50/50 blend with your HOO and RGB using: (HOO + RGB) * 0.5
then do a 50/50 blend with your HOO and RGB using: (HOO + RGB) * 0.5
Oscar's recommendation works well.
Another approach I've been experimenting with to blend my ALP-T Dual Narrowband with RGB, is to process the ALP-T data into a Foraxx Palette and then blend it into RGB to taste. I followed Paulyman Astro's OSC Narrowband processing video to generate the Foraxx version of the Dual Band data and then blend it into your RGB image to taste. I did this method with my two most recent images (Wizard and Pacman), using .8 Foraxx to .2RGB.

I found a video from Adam Block on using Imagenlend under scripts - utilities. Seems promising.
<Edited> Deleting as the pixel maths i posted was not related to the original post (I had posted about blending starless and star images). Apologies!
