It was a perfect night at a dark site in southern Alberta. The Milky Way shone to the south and aurora danced to the north.
I had scouted out this location in June and marked it on my calendar to return in the fall when the centre of the Milky Way would be well-placed to the southwest.
The site is Police Outpost Provincial Park, named for the North West Mounted Police fort that once occupied the site, guarding Canada’s sovereignty in the late 1800s.
One result from the night of shooting is the opening image, the first frame from a time-lapse taken while deep blue twilight still coloured the sky. The main peak is Chief Mountain in Montana.
A fairly mild dispay of aurora in the darkening deep blue twilight over the lake at Police Outpost Provincial Park, in southern Alberta, on September 26, 2016, with the stars of Perseus rising, and with Capella low in the northeast at centre. This is a stack of 4 x 20 second exposures for the dark ground and water to smooth noise and one 20-second exposure for the sky, all with the 25mm Canon lens at f/2.8 and Canon 6D at ISO 2000.
To the north an aurora display kicked up over the lake. While it never got very bright, it still provided a photogenic show over the still waters.
A fairly mild dispay of aurora over the lake at Police Outpost Provincial Park, in southern Alberta, on September 26, 2016, with the stars of Auriga and Taurus rising, including the Pleiades at upper right. The Hyades in Taurus are the most prominent stellar reflections at lower right, in the still water this evening. Capella is the bright star above centre; Aldebaran is at right. This is a stack of 4 x 20 second exposures for the dark ground to smooth noise and one 20-second exposure for the sky and water, all with the 25mm Canon lens at f/2.2 and Canon 6D at ISO 3200.
The waters were calm on this windless night (rare for southern Alberta), and so reflected the stars and Northern Lights beautifully.
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. 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.
Here, the Big Dipper reflects in the lake as we look north to the Lights. The movie below compiles still images and two time-lapse sequences, of the Lights and Milky Way. The sounds are the natural sounds I recorded on site, as flocks of geese were getting ready to migrate and the owls hooted.
