A stack of 434 exposures, taken for a time-lapse sequence, each exposure being 5 seconds at f/4 and with the Canon 7D at ISO 2000 and 10-22mm lens at f4. Exposures were short due to bright full Moon light and to minimize blurring of the windmill blades. A bright meteor appeared on one of the frames. The windmill is in the Wintering Hills windfarm south of Drumheller, Alberta.
