General description

An all-sky imager is a special type of camera that is designed to take pictures of the aurora in the night sky. It uses a fish-eye lens in order to view almost the whole sky from horizon to horizon. It may also use a filter to view only certain colours. The camera exposes an electronic CCD detector instead of ordinary photographic film. The CCD detector converts the camera image into electrical signals that make up a digital image that can be stored on computer.
