The stars of the northern sky over Castle Mountain in Banff National Park, Alberta. This was June 6, 2023 on a very clear night, but bright with blue summer twilight at this latitude of 51° N in June. The W of Cassiopeia and the Milky Way are at right. Polaris is at top. This is a blend of two stacked 2-minute exposures at ISO 1600 for the dark ground lit by starlight and sky light, and a single 20-second untracked exposure at ISO 2500 for the sky, all with the Canon RF15-35mm lens at 24mm and and Canon R5 camera.
