I also captured this galaxy last night and still need to add the hydrogen data. It was my first time shooting hydrogen in a galaxy, and the effect was truly wow. Now I just need to figure out how to integrate it in Siril.

Split the main image into channels (R, G, B). Then in Pixelmath: R = R + Ha, G = G, B = B. Everything will appear red, but color calibration will help. You can experiment with the coefficients in front of R and Ha.
