Night sky photographer Alan Dyer recorded this timelapse montage at the Banff, Jasper and Waterton Lakes National Parks in the Canadian Rocky Mountains over the summer of 2014. At night, he told us, these sites are “quiet and deserted, unlike by day when often hundreds of people throng these viewpoints”. The experience of recording at night with just his DSLR camera in tow was, he described, “a magical, if at times eerie experience”. Credit: Vimeo/Alan Dyer/AmazingSky.net
