Be nice to see a link to the original artist's page.

Exposure settings? Camera/lens used?
You usually just wait until very late at night in a location that has very little light pollution and do a long exposure of the sky (around 30"). Touch it up in Photoshop/Lightroom and voilà!
Sounds too inorganic.
Also since the exposure of the sky has to track on the sky, you necessarily need to capture the terrain in a separate exposure and composite them together.
Thank You, all I got was a bunch of tumblr pages when I searched for it.
Here is the EXIF:

Is there a bigger version somewhere?
