Compilation of Noctilucent Clouds at 2014 Julyの無料動画を見ましょう

You see timelapse animations.
The images were made with 2s and 5s interval.
Sometimes the full frame was downscaled and sometimes you see a 1:1 pixel copy of the frame.
Due to automatic exposure in some intervals there is unfortunately a "flash" effect in some timelapses.
