An aurora display on the night of June 7/8, 2015 from southern Alberta, with an old rustic farm truck as the foreground. This is a frame from a 450-frame time-lapse with the Nikon D750 at ISO 1600 and the Sigma 24mm lens at f/2.8, for 8 seconds each. The foreground is from a stack of 8 images adjacent in time to the sky image stacked in Mean mode for smoothing of noise.

The Northern Lights dance over the sweeping Red Deer River and Badlands of southern Alberta, from Orkney Viewpoint looking north over the valley. The Bleriot Ferry crossing is in the distance at the lights. Cassiopeia is embedded in the purple curtains. The river reflects the aurora light.

The Northern Lights over the end of Prosperous Lake, on the Ingraham Trail near Yellowknife, NWT, a popular spot for aurora watching in the area. This is looking west on the night of September 5-6, 2019 during a brighter outburst this night.
