The Big Dipper and Arcturus (at left) over a single tipi at the Two Trees site at Grasslands National Park, Saskatchewan, August 6, 2018.

This is a stack of 10 exposures, mean combined to smooth noise, for the ground, and one untracked exposure for the sky, all 30 seconds at f/2.8 with the 20mm Sigma lens and Nikon D750 at ISO 6400.

Light cloud passing through added the natural star glows, enlarging the stars and making the pattern stand out. No soft focus filter was employed, and illumination is from starlight. No light painting was employed. Some airglow and aurora colour the sky.

A Glow filter from ON1 Photo Raw applied to the sky to further soften the sky.
