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.
The summer Milky Way rising in the late night hours on May 14/15, 2018 from Dinosaur Provincial Park, Alberta. The galactic centre is at right; the Summer Triangle stars at left. A faint band of green airglow is across the south at right. This is a stack of 2 x 90-second exposures for the ground, to smooth noise, and at f/2.8 for better depth of field, plus a single 30-second untracked exposure at f/2 for the sky, All with the Laowa 15mm lens and Sony a7III camera at ISO 3200.
Circumpolar star trails and aurora over the Red Deer River, Alberta from the Orkney Viewpoint north of Drumheller on May 5, 2018. This is a stack of 650 images for the sky and river reflections using Advanced Stacker Plus actions in Ultrastreak mode. The ground comes from a stack of the final 8 images in the set, averaged to smooth noise. All exposures were 10 seconds at f/2 with the 14mm Sigma Art lens and Nikon D750 at ISO 3200. The frames were taken for a time-lapse movie of the aurora, which proved fairly quiet this night, so in stacking the sky, the aurora did not blur too much. Most of the curtain activity seen here was in the last dozen or so frames.
