Try stacking this object with drizzle, but first discard the two 600-second frames—the stars are clearly blown out—and then reprocess it.

And in which software can you stack with drizzle? Astap, Siril? Trying to get along with the EdgeHD11)

You can use Siril, which has very powerful functionality, and there is a good tutorial video available for this program.
