The International Space Station passes over Bow Lake, in Banff, Alberta, August 20, 2011. This is a stack of five 40-second exposures at f/4.5 and ISO1600 with the Canon 5D MkII and 8mm lens, taken as part of a time-lapse sequence. The gaps in the trail was caused by the 1 second interval between frames. By coincidence, an Iridium flare also happened in the same area, piercing the ISS trail. The Moon was just rising behind the camera and was beginning to light up the peaks. This was the second of two passes that night, the first across the sky but in deep twilight. In this one, the ISS goes into shadow at the zenith at centre.
