New lifer for me. Really like its hairstyle. Kind of looks like me when I wake up

Stacked using Siril and edited in GIMP

As you can see, there is a lot of noise, even with heavy editing and noise reduction in siril as well as in GIMP, and I'm out of ideas of what could cause it. I tried different exposures (from 10s to 30s), different ISOs (1600-6400). I tried to manually dither by moving the mount through the App every 30 minutes or so. I also used a lens dew heater at different temperatures ranging from 15°C to -5°C with no difference in noise.

I got a successful result a few months ago with the Orion nebula, the only differences were the exposure of 5 seconds and a Omegon Mount MiniTrack LX3 Essentials mount which couldn't be polar aligned very well. I can't imagine that the difference from 5 to 10 seconds exposure did all the difference.

Can anyone help me?

I recently took some pictures of Andromeda with a SA-GTI and a lumix g85 with the lumix 100-300mm, but the noise of the final image is really bad. Here is the first picture taken with a total of 2.5 hours (315*30s):

With this noise, I thought it was waking noise due to the almost perfect polar alignment. Since I don't have a dedicated computer and autoguider to dither, I just did it manually by moving the axis of the mount a bit to move the object on the sensor every half hour. For reference, the object stayed within the center cell of the grid of thirds, so I'd say I moved it a few hundred pixels every time in different directions. Here is the result (293*30s):

(Both pictures are processed in siril with green noise removed at the end) The noise stripes are smaller, but there is still a lot of noise in my opinion. It this due to the sort total exposure, or might it be walking noise? How can I reduce the noise without buying new equipment?
