I was searching for a lens with wide angle for my EOS 600d (timelapsevideo.eu/welches-weitwinkel-fur-die-canon-600d/ - sorry, only in german at the moment) and I was not the only one ;-)
So now you can see the result from 300 RAW-Pictures shooted at ISO 1600 with maximum aperture 3.5. 20s exposure time and pictures taken every 26s (with Magic Lantern). No exposure adaptation when the moon rises (Camara unattended), some adaptions with Adobe Lightroom and LRTimelapse (lrtimelapse.com)
The buildings belong to the Izaña Atmospheric Research Center at Tenerife - located near to Mt. Teide, Spains highest Mountain (3718m) at an altidute of nearly 2.400m.
