Circumpolar star trails over the old pioneer Larson Ranch in the Frenchman River Valley, in Grasslands National Park. Saskatchewan. Polaris is at upper left. This is facing east to the rising sky.

This is a stack of 90 images for the sky, to create the star trails, and a stack of 5 exposures taken at the beginning of the sequence for the ground, to smooth noise. Each exposure was 45 seconds at f/2.8 with the 15mm full-ftame fish-eye lens and Canon 5D MkII at ISO 5000.
