Star trails

This kind of picture you can get in a starry night. Just fix your camera on a tripod, switch to the bulb function (if available) and expose. This image was taken during three hours. In those three hours, the stars went further on, because of the rotation of earth. The builing in the foreground is the Weikersheim observatory, in which I take my astronomic pictures. See the right above the tree, it is a meteor.
