This is a "bad time lapse" because you can't really see the movement of main target - Noctilucent clouds. What we mostly see here moving, are just ordinary clouds (dark ones, in foreground). But anyway, i was curious to shoot it via time lapse, who knows, may be someone uses my clip for scientific research :))

The Noctilucent clouds are the glowing ones, in silver/blue color. More about this astronomical phenomena - en.wikipedia.org/wiki/Noctilucent_cloud
