You could spend years photographing there.... In fact that's what I plan on doing. Setting up a business to take people out for astrophotography. There are heaps of 3-4 hour astronomy tours, but few that give you time to take out your camera and capture scenes like this.

Gets a bit complex as many of the most interesting spots are closed at night (Valle de la luna etc), so I'm negotiating with indigenous leaders to see what can be done.
