I love it! So many details with the Ha added 🤩 (I still don't know how to do that btw)

Thank you so much! 😊 There are in fact several ways to add the Ha, e.g. the NBRGBCombination script in PixInsight. But this time I used a PixelMath expression and for the first time I did a proper Continuum Subtraction for the Ha using another script.

I've tried many times the NBRGB script but failed miserably. I'll keep trying 🙂

Here’s an article about a couple of other options. Maybe it’s useful.
