The Deep Sky Survey (DSS) is photographic survey of the whole sky. The project was commenced in the northern hemisphere in the 1950s using the Oschin Schmidt Camera telescope at Mount Palomar Observatory. It was completed in the southern hemisphere the 1970s, by the UK Schmidt at Siding Spring Obsevatory. Initially, the survey was published on sets of photographic plates. In the 1990s, the plates were digitised and placed on line and were also published as a one hundred volume set of CD-ROM discs. Since the initial survey, several other complete surveys have been added to the project.


Field of view: 1° square
It requires over 40,000 such images to cover the whole sky.
