I can't for the life of me figure out how to do this. I'm using siril and gimp for processing.
I captured data with an OSC with a dual narrowband filter (First time). Using siril, I processed and extracted the Ha and Oiii layers, giving me my two grayscale images, one for each spectrum.
Now, I'm trying to figure out how I convert the Ha layer to be red, and the Oiii layer to be that typical teal color, where I would then merge them with transparency, much like how stars are added back in to normal images.
My end goal would be something like this: https://www.astrobin.com/full/tybmrb/0/?q=dual%20narrowband
where the blue layer is very distinct to the red layer.
I found some tutorials about how to use siril's pixel math tool to create a blended color scheme to mimic the hubble pallete by defining RED as Ha, GREEN as 0.6*Ha+0.4*Oiii, and BLUE as Oiii. But for this shot I'm capturing, the look isn't quite what I'm going for: https://www.astrobin.com/full/8akb5n/0/?q=veil%20nebula
Any help would be appreciated!
