My first proper go at a star trails photo, taken while staying with a few buddies in a cabin near the Alps, in a valley called Konstanzer Tal between Immenstadt and Oberstaufen.
I rather like how this turned out, although there is still lots of room for improvement. The foreground isn't very spectacular and the circle is somewhat distorted due to the steep angle, it's rather hard to get a good composition when it's almost pitch black.
But you can expect more star trail photography from in the future. ;)
