I don't know if you realize this, but star trails photographs take a lot of work. You have to find a compelling foreground subject in a place that doesn't have too much light pollution. Then you have to open your shutter and ignore your camera for a while (in this case 677.0 seconds). I found, taking this photograph, that ouzo and good conversation is a great aid to ignoring your camera. I also discovered that mechanical cameras are far better suited to this sort of thing than electronic ones...two shots and my battery was dead.
