I like it. Do you have a breakdown of the workflow for integrating the Ha into Rgb with Siril?

It would be too long and confusing to write out here. I followed a YouTube video from Deep Space Astro called “Enhancing Galaxies with H alpha. https://youtu.be/77gZfGdI8aA?si=lMu6-vc-56zy29gh

Be prepared for some trial and error. I’m new to pixel math and still learning. For example after adding the Ha, I find my stars get red highlight, which I don’t like. After splitting the image into starless and Starmask, I took the starmask into photoshop and made it black and white, before recombining it with starless galaxy image.
