Circum-polar Star Trails

This type of astrophoto is the most simple and anyone can try it if their camera has a "B" (for bulb) setting on the shutter and a rigid place to mount the camera, like on a tripod. I've shot very few of this type of image and only one other with the 20D so this was a bit of an experiment. I set the ISO a bit too high, so the image isn't exactly what I was expecting. Converting it to black & white and making adjustments to the levels gave this somewhat interesting result.
Canon 20D - 2,777.4 seconds, 20mm @ f/ 5.6, ISO 800
