The aurora of September 27, 2017 from home in southern Alberta, in a view looking north toward the main auroral curtain. The Big Dipper is at left. This is a single frame from a 700-frame time-lapse. This is 4 seconds at f/1.8 with the Sigma 14mm Art lens and Nikon D750 at ISO 2500. The setting waxing Moon is providing the foreground illumination.
The Northern Lights in a decent display on September 15, 2017, from River Road north of Fort Saskatchewan amid the petrochemical plants lighting the foreground, and overlooking the North Saskatchewan River. The aurora here reaches to the zenith in a post-substorm phase of flickering or pulsating. The Big Dipper is right of centre. I shot this with the Canon 6D MkII at ISO 800 and 14mm Rokinon SP at f/2.5, for 4 seconds.
