Alright, so I've been trying to add Ha to RGB. I've managed to star align the Ha and produce a starless image. But from that point on everything just didnt work out anymore. Could someone add this Ha-data to this RGB-data and if possible record the process so I could repeat it? It would mean so much to me. Thanks.

I removed the stars from the RGB image, used this pixelmath (dragged it onto the starless RGB), then adjusted curves to manage the red hue.
the pixel math is from this video: https://www.youtube.com/watch?v=tyY6lQRrScQ
as you can see, with your Ha not being rotated like the RGB it causes some problems but you get the idea 🙂

@prisma basin thanks. I actually got the same result and thought there was something wrong with it, because there is so much more Ha visible in the pure ha image. But it seems that this is right.

Indeed there is. I changed the "1.2" to "1.4" and "1.6" and it really brought it out, but also made it harder to town down the overall red hue.
with some clever masking, i'm sure you can get a better result. 😄

how do you „fix“ the core if you do so?
because I dont really like that it becomes totally red.

that would be done with masking and curves adjustments i'd assume. i've done stuff like it before with just OSC data, to protect the galaxy core while i adjusted other stuff
this galaxy was completely red before adding the 'stars' back. the star removal considered it a star, which helped hide the red lol.
i'm not sure if you can put a range mask on the core of the galaxy before doing that pixel math or not. wouldn't hurt to try!
