A display of noctilucent clouds, the first seen from home in Alberta during the 2017 season, on June 23/24, 2017. This was a 12:43 am and the white NLCs mix with the colours of the perpetual twilight. Capella is the bright star at right of centre, circumpolar from this latitude of 51° North. This is with the 135mm telephoto and is the first frame from a 370-frame time-lapse. It is 5 seconds at f/2 and ISO 800.
Noctilucent clouds at 3 am on June 27 over a prairie pond in southern Alberta.

This is looking due north with the stars of the Big Dipper at upper left. Capella is at lower right. Shot with the 20mm lens.
