I found it quite mesmerizing. I hope others enjoy it too.

Some info on it:

Scenes taken from Tenerife, more than 2,000 meters above sea level and over a year to capture all possible shades, clouds, stars, colors from a unique landscape and from one of the best skies on the planet.
First in a series of videos nocturnal and crepuscular Time Lapse taken in the Canary Islands trying to capture the beauty of each island.
To capture the natural movement of the earth, stars, clouds, sun and moon TimeLapse technique was used, Dolly vertical and horizontal rails, spindles with horizontal and vertical movements. HDR data collection.

I wonder how he moved the camera while doing timelapse. Some movements can be made with motorized head, but there are some long straight movements... rails and dolly??

Great video, thanks for sharing! If anyone's interested, this company makes motorized sliders. Very pricey, though! Maybe I'm just cheap. 

I'm working on building my own for less.

thanks for this

That one is equally as beautiful. I saw it a few weeks ago too.

Wow, that's amazing! How does one capture so much light from the sky?

But then don't you get streaks at this speed? Or are they just not noticable at the size of these videos, and their movement? I remember having tried that in the past, never got dots, but streaks.

Take a look at timescapes.org and not only will you see some of the most beautiful astro-lapeses in existence, but you can learn quite a bit, too!
