This is a couple of timelapses done with my Canon 40D. The first is 45 sec long exposures at f/9 and 55mm shot over the course of 2.5 hours. You can see Cassiopeia rotate around, as well as Polaris in the upper right. The second is of the moon through clouds and trees on a windy night. Consisting of 15 second long exposures set at f/9 and 50mm, this was shot over the course of a little more than an hour. Still shots were all taken with my Canon 40D, except for one lone Powershot S1 IS shot. None had any tracking other than Orion, which is a stack of over 2.5 hours worth of information.
