Plains Milky Way from Randy Halverson on Vimeo.
Another beautiful Milky Way time-lapse video, this one from the Great Plains. Click the arrows to the right of the "HD" for the full-screen.
During the month of May, I shot Milky Way time-lapse 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, with Sigma, Tamron and Tonika lenses, 1600 ISO.
I have got to get out of the city one of these nights.
