Noctilucent clouds at 3 am on June 27 over a prairie pond in southern Alberta. The NLCs were visible as an arc across the north for at least 2 hours and were still there as dawn twilight brightened at 3:30 am. This is looking due north with the bowl of the Big Dipper at upper left. Capella is at lower right. Shot with the 24mm lens.
Looking due north at midnight on June 26/27 at Forget-Me-Not Pond in Kananaskis, Alberta, with the sky bright with perpetual solstice twilight that brightens the sky and tints it blue all night near summer solstice at this latitude (51° N). This is a stack of 4 exposures for the ground, Mean combined to smooth noise, and one exposure for the sky and water to keep stars as points. All for 30 seconds at f/2.2 and ISO 800 with the 24mm Sigma lens and Nikon D750.
The autumn stars and constellations rising in the northeast at Forget-Me-Not Pond at the end of Highway 66 in Kananaskis, Alberta, on June 26, 2016. Cassiopeia is at top, Perseus at left, and Andromeda at centre. The yellow glow is not twilight but light pollution from Calgary. The sky is blue with solstice twilight. This was taken near midnight. The ground is a stack of 4 exposures, Mean combined to reduce noise, while the sky and water are from one exposure to keep the stars as pinpoints.
