The northern summer Milky Way rising on a spring night at Dinosaur Provincal Park, Alberta. This is a 180° panorama from northwest, at left, where the waxing crescent Moon is setting, over to southeast, at right, where Scorpius and the galactic centre is rising. The Summer Triangle stars are at centre; Cassiopeia is left of centre; Auriga and Gemini are setting at far left amid the glow of the setting Moon. The sky was hazy, adding the natural star glows, horizon clouds and tints. No light pollution or starglow filter was employed. This was May 15/16, 2021 about 1 am. This is a blend of tracked exposures for the sky and untracked exposures for the ground. The sky is a stitch of 9 segments at 30° spacings, each 1 minute at ISO 1600 with the original Canon 24mm L lens at f/2. The camera was in portrait orientation. The ground is a stitch of 18 segments at 15° spacings and taken after the sky segments with the tracker motor off, each ground segment 2 minutes at ISO 3200 with the lens at f/4 for more depth of field. Both passes were single row panoramas, with the camera unchanged in altitude. All with the Canon EOS Ra camera on the Move-Shoot-Move (MSM) rotator/tracker with the Alyn Wallace Z Plate to allow the camera to pan horizontally on the level, despite the tracker being tipped over polar aligned. All stitching was with Adobe Camera Raw, to create two panoramas, which were then layered, masked (using Select Sky) and blended in Photoshop. A mild Orton glow effect added with Luminar AI. I have left some satellites in.
