N. Autumn constellations rising, taken with 15mm lens and Canon 20Da for stack of 2 x 50s at ISO1600 and f/2.8. Taken Sept 30, 2008. Fixed camera on tripod, no tracking. Glow layer added to punch up stars.
A single-frame panorama with the 15mm ultrawide fish-eye lens of the autumn sky and constellations from horizon to zenith. The sky extends from Cetus at bottom up to Cassiopeia and Cepheus at top in the Milky Way. The Pleiades is at left, the Andromeda Galaxy above centre. Capella and Auriga are at upper left. The evening Zodiacal Light brightens the sky at lower right, plus haze is moving in and reflecting light pollution to the west. Taken from home in southern Alberta on Jan 3, 2016, with the 15mm full-frame fish-eye lens at f/3.2 and Canon 5D MkII at ISO 800 for a stack of 5 x 3-minute exposures, Median combined to eliminate satellite trails. The ground is from one exposure to minimize blurring from the camera tracking.
The autumn constellations rising over the autumn trees at Driftwood Beach, Waterton Lakes National Park, Alberta, Canada, on a moonless night on September 24, 2016. The Pleiades is at lower right, the Andromeda Galaxy at upper right. The W of Cassiopeia is at upper left, Capella in Auriga is at lower right. Perseus is centre right. Illumination is from starlight and by lights from the glow of the townsite across the lake. Faint bands of red airglow are visible in the sky. This is a stack of 8 x 30 second exposures, mean combined to smooth noise, plus one 30-second exposure for the sky, all with the Sigma 20mm lens at f/2.5 and Nikon D750 at ISO 4000.
