Star Trails over the Canada-France-Hawaii Telescope

Explanation: Just fix your camera to a tripod and you too can make an image of graceful trails traced by the stars as planet Earth rotates on its axis. Making a time lapse video like that shown above may require more effort, though. Made on 2006 October 13 from Mauna Kea , Hawaii , USA , this video nicely captured what you might see of the night sky if you could keep your brain from changing your perceived visual image about every hundredth of a second. Starting from a dark sky and point-like stars, the video demonstrates how stars appear to move over the night as the world turns . Near the center of the developing bull's-eye pattern is Polaris , the North Star. Visible in the left foreground is the 3.7-meter aperture Canada-France-Hawaii Telescope (CFHT). The red glow that illuminated the CFHT dome near the beginning of the film was created by a car leaving the volcanic summit . The Moon rose about half way through the video and created a white glow that gradually illuminated most of the CFHT dome. The above remarkable time-lapse video was constructed from about 1,000 consecutive frames taken with a digital camera over nearly nine hours.
