Seven Days | Chris Welsby

Each day starts at the time of local sunrise and ends at the time of local sunset. One frame was taken every ten seconds throughout the hours of daylight. The camera was mounted on an equatorial stand which is a piece of equipment used by astronomers to track the stars. In order to remain stationary in relation to the star field, the mounting is aligned with the Earth's axis and rotates about its own axis at approximately once every 24 hours.
