Two bright Perseid meteors (the best two from 3 hours of shooting) over the moonlit landscape of Dinosaur Provincial Park, Alberta, on August 12/13, 2017. The waning gibbous Moon is off frame at right providing the illumination. Smoke in the air from BC forest fires provides the banding and haze in the sky. A faint aurora colours the horizon yellow-green. The meteors point back to the radiant point in Perseus. The Double Cluster is at centre; M31, the Andromeda Galaxy, is at right. Capella is low above the northeast horizon. Polaris is just above the upper meteor. The base image contains the sky and ground, and the meteor at upper left. The bright meteor at centre is from a later exposure, with its layer blended with Lighten mode and masked to reveal only the meteor, and rotated to align its sky to the base image sky, so the meteor is in the correct location with respect to the stars. The exposures were part of a 400-frame time-lapse taken with the Canon 6D Mark II and Rokinon 14mm f/2.5 SP lens, for 25-second exposures at ISO 3200.
