Star Trails

A star trails photo is created by setting a camera on a tripod and opening its shutter for at least an hour.
The rotation of the Earth makes the stars appear to travel in circles.
If you're interested in photographing star trails, see my article "As the World Turns" in Sky & Telescope, November 2003.
You can purchase it from their archive.
