A competitive entry has arrived!) Mine is still awaiting processing. By the way, like me, you have the issue with shifted blue/purple on the stars.

Zhenyok, forget about the blue shift! Just enjoy Ira's journey as an already accomplished astrophotographer in the community of amateur astronomy enthusiasts from Russia!

No one disputes Irina's competence, that's why I wrote that the work is competitive. And there's no need to give up—solving this problem will be an achievement for both me and her. Especially on such a serious project, everything should be in the best possible form.)

I don't know, I don't see a serious problem yet). If you really want to nitpick, you can find a problem anywhere). Do it better, and while you're at it, share how to remove the purple color of the stars.

The purple itself is removed easily (inversion + SCNR), but removing the shift is another question. The problem isn't serious, of course) But it would be good to solve it. If I find a solution, I'll definitely share it)

If you also had standard framing, we could combine the accumulations to make a collaborative image. I have 19 hours of LRGB and 40 of hydrogen.

I don't really like group shots... Then we'll be waiting for a masterpiece from you!)

I have a total of 16 hours (RGB+Ha). We can stack it as an experiment.

Ir is just the bomb! You blew up DSX! I remember your whole journey, from crooked shots to beautiful nebulae! Now this - well done!
