An extensive display of noctilucent clouds starting the evening nearly up to the zenith and covering all of the northern half of the sky on June 27, 2021. This frame is from later in the evening and shows the tops of the clouds starting to turn red as they enter into Earth's shadow and are illuminated only by the red light of the setting Sun as seen from that high altitude in the atmosphere. I shot this from home in southern Alberta, as part of a time-lapse sequence. The camera is aimed almost due north here. Polaris is at upper centre. This is a single shot with the TTArtisan 11mm full-frame fish-eye lens at f/2.8 and on the Canon R6.

A panorama of noctilucent clouds in the waning stages of a great display, as they retreated to a low but bright band across the northwest and northern horizon, here over the wind-rippled waters of Crawling Valley Reservoir near home in southern Alberta. The wind prevented the ideal reflection. This was June 20, 2021, the evening of summer solstice this year. So this was the shortest night of the year with the Sun the least distance below the horizon it would get for us at my latitude of 51° N. The colours blend the blue, yellow and orange of the solstice twilight with the blue-white of the NLCs, with a slight reddish tinge at the tops of the clouds where the Sun is setting. This is a 5-section panorama with the 85mm Samyang lens and Canon R6, stitched with Adobe Camera Raw.
