Those are fantastic!!  Great job!!  And thanks for posting!

Do you stack multiple images for the pictures you posted, or were these only single images?

edit - Probably kind of hard to stack a 2 hour image because it'd be daylight after a couple images, but maybe the shorter ones.

I'm glad you asked!

I usually run either 10sec subs or 20sec subs. If its breezy or during a full moon. Its 10sec subs to avoid rejections. If its very dark and still, I will use 20sec subs to pull out a bit more detail. I then use Siril to manually stack the .FIT files. I wrote a script that upscales the image and also does frame rejection. If a satellite goes through the frame, or a breeze makes the stars fuzzy. It will auto reject. Makes my life a bit easier.
