The summer Milky Way over a tent at the Meadows Campground at the Saskatchewan Summer Star Party, in Cypress Hills Saskatchewan. This is a stack of 4 x 2 minute exposures at f/2.8 with the Canon 24mm lens and Canon 5DMkII at ISO 1600. The foreground is from one exposure; the foreground is masked out of the other 3 images in the stack to minimize blurring of the foreground by the tracking camera.
The Sagittarius Milky Way area, around the centre of the Galaxy, over the trees and campsite at Cypress Hills Interprovincial Park, Sasksatchewan. Taken August 16, 2012 at the Saskatchewan Summer Star Party. This is a composite of 6 exposures: all 2 minutes at f/2.8 and ISO 1600 with the Canon 5D MkII and Sigma 50mm lens, but 5 exposures were tracked and 1 exposure was untracked to prevent the ground from blurring. Ground is from the untracked exposure, sky is from the stack of 5 tracked exposures.
