Milky Way Panorama over Dinosaur Park

This is a 160°-wide panorama of the Milky Way arching over the Badlands formations at Dinosaur Provincial Park, Alberta, taken on a moonlit night in May.

The waxing crescent Moon is low and off frame at left and is providing the warm illumination. Capella is the bright star at far left. The Summer Triangle stars are right of centre, with bright Vega at top. Cassiopeia and Perseus are at left; Cygnus is at centre. Haze in the sky adds the natural star glows but also mutes the contrast in the Milky Way and adds the horizon glows. However, a weak aurora adds a green and magenta glow to the northern horizon at centre.

This is a blend of a 6-segment panorama framed for the sky, with a matching 6-segment panorama framed for the ground, layered, masked and blended in Photoshop. Segments were spaced 30° apart with the camera in landscape orientation.

The sky segments are untracked, each 20 seconds at f/2.8 with the Sigma 24mm Art lens. The ground segments are each 30 seconds also at f/2.8. All were with the Canon R6 at ISO 3200. I should have used 1 to 2 minutes each for the ground panorama, shot at a lower ISO, but it was late! Stitching was with Adobe Camera Raw. I applied a mild Orton glow effect using Luminar AI.
