Composed of 159 images spaced ten seconds apart, which is about 26 minutes.
Taken with a Canon EOS 20D looking out the back door.
The sunset was at 6:13pm, but the first shot was taken at 6:34pm. I was a little late in getting set up. The final shot was taken right at 7:00pm and the camera battery died. It's too bad, there was clearly still plenty of color in the sky!
