The Big Dipper reflected in the still waters of the lake at Police Outpost Provincial Park, in southern Alberta, on September 26, 2016, with an aurora to the north at right. Only in autumn can one shoot the Dipper reflected in the water in the evening sky, as it is then riding low along the northern horizon. This is from a latitude of 49° N where the Dipper is circumpolar. It is also called the Plough in Great Britain. This is a stack of 4 x 25 second exposures for the dark ground to smooth noise and one 25-second exposure for the sky and water, all with the 25mm Canon lens at f/2.2 and Canon 6D at ISO 3200. Taken with dark frame LENR on.
The Big Dipper in hazy clouds over the Waterton River at Maskinonge Pond, September 23, 2016, taken at the Night Photography Workshop I conducted there that night. The glow at right is light pollution from the Shell Waterton Gas Plant and from Pincher Creek to the north. This is a stack of 5 x 30 second exposures, mean combined to smooth noise, and one 30-second exposure for the sky, all with the Sigma 20mm lens at f/2.2, and Nikon D750 at ISO 3200.
A diffuse arc of aurora and the rising waning gibbous Moon light the sky over the old barn near home at harvest time, September 19, 2016. The glows from Strathmore and Calgary light the clouds to the west at far left. The Big Dipper shines over the barn, with Capella and the stars of Perseus at right. The Pleiades are rising to the left of the Moon. This is a panorama of 5 segments, with the 20mm lens and Nikon D750. Stitched with ACR.
