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.

This is a stack of 10 x 10-second exposures for the ground, mean combined to smooth noise, plus 4 x 10-second exposures for the sky (registered in Photoshop).

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.
