These pictures usually get taken at 15-30 secs with a very fast lens (f2.8) and an ISO of 1600-6400. You need a pretty dark sky or a lot of post processing. Within 50-100 miles of the background is just brown.

If you have a camera with manual control, give it a try. You need a wide angle lens, otherwise you'll get star trails quickly.
