A 360° panorama of the winter sky over Dinosaur Provincial Park, Alberta, on February 28, 2017. The Milky Way arches across the sky from south (left) to northeast (right). The Zodiacal Light stretches up from the western horizon at centre. The Gegenschein is faintly visible above the horizon at far left in Leo. Orion is left of centre; the Pleiades sit at the tip of the Zodiacal Light pyramid of light. The ground is lit only by starlight. No artificial illumination or light painting applied. This is a stitch of 6 segments taken with the 12mm full-fame fish-eye Rokinon lens at f/2.8, all 30-second exposures with the Nikon D750 at ISO 6400. The camera was aimed portrait with the segments at 60° spacings. Stitched with PTGui using equirectangular projection with the zeith pulled down slightly.
A 270° panorama of the northern hemisphere winter Milky Way, from Puppis at left, to Perseus at right, with Orion and Taurus at centre. Canopus is just above the horizon at left of centre. The Milky Way is marked with many dark clouds of interstellar dust, especially in Taurus at centre. I shot this from the Quailway Cottage in southeastern Arizona at a latitude of 31° N. on December 12, 2017. It is a stitch of 8 segments, each with the 14mm Rokinon SP lens at f/2.5 and modified Canon 5D MkII at ISO 6400, for 45 seconds each. The camera was oriented portrait. Stitching was with PTGui, using the Full-Frame Fish-eye projection to avoid distortion to the sky overhead, but creating the “wrap-around” effect at the sides.
