A scene of Earth and sky, with stars over the late Cretaceous sedimentary layers of the Red Deer River Badlands. Hercules and Corona Borealis at right rising in the northeast over the moonlit Hoodoos on Highway 10 east of Drumheller, Alberta. Light from the waxing gibbous Moon provides the illumination on April 26, 2018. This is a stack of 8 x 10-second exposures for the ground to smooth noise, and one 10-second exposure for the sky, all at f/4 with the Rokinon 14mm SP lens and Sony a7III camera at ISO 1600. Nik Sharpener applied to the ground.
A 220° panorama from west (left) to east (right) of the bright aurora in a classic arc across the north, on April 19, 2019. This was from a roadside pullout on Highway 564 north of Strathmore, Alberta. The waxing crescent Moon is setting at left in the northwest; Jupiter is rising at far right in the southeast. The lights of Calgary light the sky and clouds at far left. This is a 10-section panorama stitched with Camera Raw. All 8-second exposures at f/2.8 with the Sigma 24mm Art lens and Nikon D750 at ISO 1600.
Orion and the stars of winter setting over the downtown core of Calgary, on April 19, 2018. I shot this from Tom Campbell Park, looking west. Venus is the bright object at far right; Sirius is the bright star at far left, with both flanking the skyline. Above is the waxing crescent Moon. The Pleiades is above Venus. This is a stack of 4 x 2-second exposures taken for a time-lapse and star trail set, all with the 24mm Sigma Art lens at f/2.8 and Nikon D750 at ISO 400. The Moon is from an HDR-blend of shorter exposures so its disk does not overexpose into a bright blob in the thin cloud. It better depicts the scene the way the eye saw it, though in this case the camera is picking out stars better than the eye could with all the foreground lighting and glare. No light pollution filter was employed.
