Orion rising behind the iconic Hoodoos on Highway 10 east of Drumheller, Alberta, near East Coulee, on a moonless January night, with illumination by starlight and by a nearby yardlight providing some shadows and warmer illumination. Clouds are beginning to move in and are providing the natural star glows. This is a stack of 10 x 10-second exposures for the ground, mean combined to smooth noise, plus one 10-second exposure for the sky to minimize trailing. All at f/2.8 with the 24mm Sigma Art lens and Nikon D750 at ISO 3200. Taken January 10, 2016.

The constellation of Orion and the bright star Sirius in Canis Major, down my country road, on a very cold and frosty moonless January night, with the temperature at -25° C. But no wind! This a stack of 5 x 15-second exposures, untracked, for the ground, stacked with mean combine mode to smooth noise, plus a single exposure for the sky, to keep the stars as pinpoint as possible. All at f/2 with Sigma 24mm Art lens and the Nikon D750 at ISO 3200. The image serves as a good workshop example of Rule of Thirds composition.
