During my travels around the world I spent 5 days in San Pedro de Atacama. I didn't see one clouds in that time but the light around sunrise and sunset was still magical, especially when the landscape began to glow.
This photo is a subtle time blend of a photo I took for the stars roughly an hour before sunrise and then a photo for the land and the right portion of the sky, just minutes before the sun came up.
Btw I have a free Tutorial on how I used Noise Averaging to create a clean sky with stars in this one: https://youtu.be/7i5YdXu8s0Q
