A 200+ degree panorama of the arch of the winter Milky Way, from south (left) to northwest (ar right) with the Zodiacal Light to the west at centre. This was from Dinosaur Provincial Park in southern Alberta on February 28, 2017. A spell of warm weather left very little snow, so the landscape does not look like winter here. But the sky is! This is a stitch of 6 segments but warped with fish-eye projection so that only 3 or 4 segments are contributing to this image. Stitched with PTGui. Each segment was 30 seconds at f/2.8 with the Rokinon 12mm lens and Nikon D750 at ISO 6400. Nik Dfine and Topaz noise reduction applied, in addition to ACR.
A composite of images of the waning Moon in the dawn sky of July 2017, with a series of close-ups taken with the 130mm refractor and Canon 60Da camera, and most with the 2X Barlow lens to further magnify the image. The sequence progresses from a 19-day-old moon (at far right) to a 26-day-old Moon (at far left). In this set, the sequence progresses in time from right to left, reflecting the Moon’s motion from west to east (right to left) across the sky from night to night due to its orbital motion around Earth. Each morning, the Moon appears farther to the left, or east, as seen from the northern hemisphere.
