During the month of May, I shot Milky Way timelapse in central South Dakota, when I had the time, and the weather cooperated. The biggest challenge was cloudy nights and the wind. There were very few nights, when I could shoot, that were perfectly clear, and often the wind was blowing 25mph +. That made it hard to get the shots I wanted. I kept most of the shots low to the ground, so the wind wouldn't catch the setup and cause camera shake, or blow it over. I used a Stage Zero Dolly on the dolly shots and a "Milapse" mount on the panning ones. Canon 60D and T2i Tokina 11-16 Sigma 20mm F1.8 Tamron 17-50 Dynamic Perception Stage Zero Dolly http://www.dynamicperception.com Shot in RAW format, the Milky Way shots were 30 seconds exposure F2.8 or F1.8 with 3 second interval between shots, for 3-4 hours run time. ISO 1600 Ten seconds of the video is about 2 hours 20 minutes in real time. Simon Wilkinson from http://www.thebluemask.com scored the soundtrack "Exodus" for the video For licensing contact http://www.dakotalapse.com
