A composite blend illustrating the radiant point of the Perseid meteor shower in Perseus at left, taken on the night of the peak, August 12, 2021, ffrom Dinosaur Provincial Park, Alberta. A couple of non-Perseid meteors also appear in the scene. The brightest Perseid, at bottom, left a yellowish ionized trail that appeared on several frames. Bands of red and green airglow tint the sky. The Pleiades are just rising at bottom, as is Capella in Auriga at lower left. Cassiopeia is above the radiant point. The Andromeda Galaxy is at centre. This is a stack of 27 x 1-minute tracked exposures at ISO 3200 with the Canon 6D and Rokinon 14mm SP lens at f/2.8, on the Star Adventurer tracker, for the sky and meteors, blended with a stack of 4 x 2-minute untracked exposures for the ground, taken at the beginning of the sequence. With all the sky images taken on a tracker, they all align and so the meteors do appear where they actually did against the background stars, preserving the effect of the radiant.
