Mars (at left) and the galactic centre area of the summer Milky Way low over the southern horizon at Writing-on-Stone Provincial Park, Alberta, on June 8/9, 2018. Sagittarus is at centre, with Scorpius at right. The Messier 6 and 7 open star clusters are just above the horizon at centre, just right of the Sweetgrass Hills on the horizon in Montana. This is a stack of 12 exposures for the ground, mean combined to smooth noise, and 1 exposure for the sky, all 30 seconds at f/2 with the Laowa 15mm lens on the Sony a7III camera at ISO 6400. These were the last frames in a 340-frame time-lapse sequence. At this time of year, the sky is always bright with deep blue perpetual twilight.
The 1910 Liberty Schoolhouse, a pioneer one-room school, on the Alberta prairie near Majorville, in the moonlight with an aurora across the north. Polaris is at top left. Cassiopeia is above the school. The 8-day waxing Moon provides the illumination. This is a stack of 4 exposures mean blended for the ground to smooth noise and one exposure for the sky, all 30 seconds at f/2.8 with the 15mm Loawa lens and Sony a7III at ISO 800. Special effect Luminar filters applied to the ground to add a vintage look to the scene.
The 1910 Liberty Schoolhouse, a classic pioneer one-room school, on the Alberta prairie under the stars on a spring night, with circumpolar star trails circling Polaris, and an aurora dancing to the north. Moonlight from the 8-day-old waxing Moon provides the illumination. This is a stack of 155 exposures for the sky for the star trails, and a mean-combined stack of 8 exposures for the ground to smooth noise, with a vintage effect using Luminar applied to the ground for the rustic tone. Star trail stacking with Advanced Stacker Plus Actions in Photoshop with Ultrastreaks effect. With the Laowa 15mm lens and Sony a7III camera. All 20 seconds at f/2.8 and at ISO 800, and taken as part of a 360-frame time-lapse.
