This sequence of 90 images spans an actual time interval of 13 minutes, during which Comet Pan-STARRS was passing through tree branches (out of focus) and clouds, as it slowly set in the west on cold and very windy night.

Image details:  90 2-second exposures at ISO 1600, taken with a Canon 400D camera and a 12-inch Meade telescope at f/7.
