A single image of the brightest section of the massive "grand display" of noctilucent clouds at dusk on June 16, 2021 from "One Tree Hill" (my name for it!) near home in southern Alberta. This display was bright and extensive at dusk on June 16, and re-appeared over much of the northeastern sky at dawn on June 17. Note the colours — with the NLCs having a reddish tinge at the top where sunlight is reddened as the Sun sets from that altitude and location of the clouds. The lower areas of NLCs often appear green as well. But the main colour of NLCs is electric blue, very much so this night when they were so bright.

This is a single image with the 85mm Samyang lens and Canon R6.
