Noctilucent clouds (NLC) on July 25.-26. 2005 as seen from Langhus, Norway

A time-lapse sequence of Noctilucent clouds as seen from Langhus, Norway (N59°45'14" E10°50'38" A115m) on the night between July 25.-26. 2005.

A total of 526 images where obtained from 21:20 to 00:15 UTC using 3 images per minute (20 seconds interval) and later assembled

into a time-lapse movie at 10fps. This effectively speeds up the motion by a factor of 200, effectively compressing the ~2

hours 55 minutes of duration down to 52 seconds. The images were obtained using a Canon 20D @ ISO200 equipped with a 15mm f/3,5

semi-fisheye and exposure ranging from 0.7 to 10 seconds.
