This is a panorama of the ground and sky framing the badlands of Dinosaur Provincial Park, in the Red Deer River valley in Alberta, with the summer sky above filled with three dozen meteors from the annual Perseid meteor shower, of August 12, 2023. The meteors all appear to be streaking away from the radiant point in Perseus at far left. The location is the upper viewpoint near the Park Entrance, and looking northeast to southeast. The lights in the valley below are from the campground and service centre. The one glaring sodium vapour light should be removed or at least shielded. The brightest horizon glow at right is from Medicine Hat. Some bands of green and red airglow tint the sky naturally. The meteor trails nicely demonstrate the green to red transition in their colours as they descend into the atmosphere and burn up. Tech Data — This is a blend of two panoramas: a panorama of two untracked segments for the ground taken in blue hour before the sky got dark, blended with a base panorama of two segments for the sky taken later with the sky darker, and with the sky segments and meteors taken with the cameras tracking the Onto the base sky panorama I layered some 32 images containing most of the meteors. The sky segments and meteors were taken with two cameras operating simultaneously, each Canon EOS R cameras, and each with 15mm lenses: the Canon RF 15-35mm and the Venus Optics Laowa 15mm, both at and for 1-minute exposures at ISO 1600, all tracked, one on the Star Adventurer 2i and one on the Star Adventurer Mini trackers. Differences in optical quality between the lenses does spoil the panorama blend — this was an experiment! It sort of worked! Lens distortions required cutting off more of the image at left and right than I had anticipated. And placing the meteors took a lot more manual alignment than planned, despite all being taken on trackers, so the location of the meteors can only be taken as "representative," not accurate! I have exerc
