This is a composite image showing a pass of the International Space Station on June 21, 2011, summer solstice night, taken from my home in southern Alberta. This is from a stack of 104 3-second exposures at f/4 with the 8mm Sigma fish-eye lens and Canon 5D MkII camera. North is at the bottom, west to the left and east to the right. The images were stacked with Chris Schur’s Photoshop Action for creating star trails.
