Red Rock Canyon in Waterton Lakes National Park, with the Milky Way, and with the landscape illuminated only by starlight.
This is a composite of two exposures taken with the same fixed camera: 60s untracked for the sky and 180s untracked for the ground, both with the 15mm lens at f/2.8 and Canon 6D at ISO 3200 for the sky exposure and ISO 2500 for the ground exposure. Masked in Photoshop.
