Aurora & Star Trails at Larson Ranch, Grasslands.jpg
A circumpolar star trail composite, shot at the old Larson Ranch site in the Frenchman Valley at Grasslands National Park, Saskatchewan, August 27/28, 2014. The pioneer cabin was the home of the legendary western author and movie star Will James, born Ernest Dufault in Quebec. He lived in this cabin when he worked the ranches in the area. The aurora was excellent this night. This is a stack of 20 1-minute exposures at ISO 2500 with the 15mm full-frame fish-eye lens at f/3.2 and the Canon 6D. The foreground and point-like stars are from the first frame in the series.
