The Milky Way over Maskinonge Lake at Waterton Lakes National Park, Alberta, Canada, on June 17/18, 2018. This was an unusually calm night, allowing the reflections of the stars in the lake waters. Jupiter is in Libra at far right. Saturn is Sagittarius in the Milky Way at left of centre. Scorpius is in between. The sky is deep blue from solstice twilight. The Maskinonge area is a sacred site to the Blackfoot Nation. This is a two-section panorama, with the ground a stack of 5 exposures for each section to smooth noise, with the sky and stellar reflections coming from one exposure for each segment to minimize trailing. All 25 seconds at f/2.2 with the 20mm Sigma Art lens and Nikon D750 at ISO 3200. Stiching with Photoshop Photomerge.
A 360° panorama of the August night sky and Milky Way over the Great Sandhills of western Saskatchewan, from the trail at the top of Boot Hill ridge. The Galactic Centre to the south is at centre, with Mars bright to the east (left) of the Milky Way. Jupiter is just setting to the right. The Big Dipper is at far right to the northwest. The last vestiges of twilight light the horizon to the north at far left and right. Bands of green airglow invisible to the eye but obvious to the camera cross the sky from west to east, and to the east some of the airglow appears red. There is no aurora visible here. A Perseid meteor streaks toward Mars. There are also several satellites in the scene — they are impossible to avoid! A band of forest fire smoke darkens the horizon to the south. This is a stitch of 30 segments, in three tiers of 10 segments each, each frame being 30 seconds at f/2.8 with the Sigma 20mm lens and Nikon D750 at ISO 6400. Stitched with PTGui. Shot with the Syrp Genie Mini in its panorama mode.
