Holy shit this is so good. Did you stabilize the camera to earth's rotation, or is this a really short exposure?

No stabilization, just a 30 second exposure! I do have a Star Adventurer with which I did this 11 minute exposure as a test last winter. This autumn/winter I intend on aiming it at a target https://p.drkt.eu/2023/11-minute-exposure.jpg
Hopefully I'll get a shot like this, but with much more pronounced colors.
Part of why I thought this was stabilized is because of the minimal streaking around the stars from the earth's rotation.
I've tried taking astro photos at 30s exposure, but they become streaky like this one 
. I guess that might change a bit if I were to switch to a wider lense or use an actual dslr.

That doesn't look like the rotation of the earth to me, but more like you bumped the camera during the exposure. Does this camera have some sort of internal stabilizer that might have still been adjusting when you started the exposure?
If you notice the stars in your picture, it's like they have a weaker tail where as earths rotation would cause it to appear as a single, solid line. see this example https://p.drkt.eu/2023/_MG_4474.jpg
