Horizon-to-zenith panorama of the northern winter sky, from Canis Major in the south just above the horizon to Cassiopeia past the zenith at the top of the frame. Capella is near the zenith above centre. The extra star at left is Mars, just 10 days past opposition, on Feb. 9, 2010, when it was just above the Beehive star cluster. Taken with Canon 5DMkII and Canon 15mm lens, at f/5 for stack of 3 exposures x 4.5 minutes each at ISO 800. Two exposures had frost on the lens, thus the big star haloes. Taken from southern Alberta, Canada.
