I was figuring out how to add Ha data in Siril through continuum subtraction; using a ready-made Python script, it turns out to be extremely simple—you just need to select the r, g, b, Ha channels and use the sliders to adjust the values that satisfy you. I really liked the continuum subtraction plugin, and most importantly for me, as someone who is not good with PCs, the plugin's interface is very simple.

Added hydrogen data via median in pixel math; here's the result. Maybe more hydrogen signal is needed, not sure — it's a matter of taste.
