The key is an equatorial mount with a spinning axis aligned along the same axis as the Earth's poles, countering the Earth's rotation as it films. It's a startling effect but plenty of films like this have been made, it's not a complicated shot and doesn't require a lot of expensive kit. Since it uses a normal camera without the magnification of an astronomical telescope it's actually quite a bit simpler than even the most basic time lapse astrophotography which a lot of amateurs do.

Or anything else involved but, the cloud in the sky bothers me a bit.

It's the gaseous core of the Milky Way as it appears to move across the sky. You can only see it with a long exposure, usually about twenty five seconds for each frame.

This is one of the best time lapses I've ever seen.

IIRC it was the Greeks that named this edge-on view of our galaxy

Similar concept shot as a timelapse over 24 hours.

The change from day to night and back is really cool.
