The International Space Station performs a pass low across the southern sky on February 10, 2013, with Canadian astronaut Chris Hadfield on board. This is a stack of 2 4-minute exposures, one with the ISS -- that one was used for the foreground. The second exposure has the foreground masked out to minimize blurring but helps smooth noise in the sky. Taken with the Canon 5D MkII at ISO 800 and 15mm lens at f/3.5.
The Zodiacal Light in the evening western sky, from the northern hemisphere, on a snowy February evening under very clear skies. Taken from home in rural Alberta, with the Canon 15mm lens and Canon 5D MkII camera at ISO 800 for a stack of 4 x 4 minute exposures at f/3.5, though the ground is from just one exposure. Taken from southern Alberta, Canada.
The winter constellations of the northern hemisphere sky, rising on a January night, from Canada, above a snowy prairie landscape. Sirius is just rising in the horizon glow. The scene extends up to Capella in Auriga near the zenith at top. Jupiter is the bright object above centre in Taurus. Taken from home on January 6, 2013, with the modified Canon 5D Mark II at ISO 800 and 15mm Canon lens at f/2.8, for a stack of 3 x 4 minute exposures. The landscape is from just one frame, to avoid blurring of the horizon. Light polluted haze moving in from the right, west. Taken from southern Alberta, Canada.
