Part of the constellation of Cygnus, 1880s. This albumen silver print was obtained from a glass negative exposed on 13 August 1885, by the French astronomer and brothers Paul and Prosper Henry. They used a new photographic technique to track the stars across the night sky during long exposures. This revealed numerous distant stars that are not visible to the naked eye. | |
