A scene of Earth and sky, with Big Dipper over the late Cretaceous sedimentary layers of the Red Deer River Badlands. The Big Dipper is at top pointing down to Polaris and the Little Dipper, over the moonlit Badlands 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 5 x 15-second exposures for the ground to smooth noise, and one 15-second exposure for the sky, all at f/4 with the Rokinon 14mm SP lens and Sony a7III camera at ISO 800. Nik Sharpener applied to the ground. The Dipper is distorted slightly by the pincushion distortion of the 14mm lens. The Moon off frame to the right adds the gradient to the sky.

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.
