The northern summer Milky Way over the Saskatchewan Summer Star Party in Cypress Hills, Saskatchewan, Canada, August 18, 2012. Taken with the Canon 5D MkII at ISO 800 and 15mm lens at f/4 for a stack (mean combined) of four 5 minute exposures, all tracked. The ground is from only one of those expoures (the gorund is masked out in the other layers).
The Sagittarius Milky Way area, around the centre of the Galaxy, over the trees and campsite at Cypress Hills Interprovincial Park, Sasksatchewan. Taken August 17, 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. All taken from the same location -- the ground is not faked onto a separate sky shot. The horizon is in its true location.
The North America Nebula (NGC 7000) and Pelican Nebula (IC 5070) area near Deneb in Cygnus. Taken from home July 24, 2012 with Canon 5D MkII camera at ISO 800 and Canon 200mm L-series lens at f/3.5 for stack of 2 x 5 minutes exposures, mean combined, plus 2 x 5 minute exposures with haze in sky which added the star glows.
