Description
This collection consists of photographs from the National Geographic Society – Palomar Observatory Sky Survey (NGS-POSS). From 1948 to 1958 astronomers at the California Institute of Technology's Palomar Observatory used a 48-inch Schmidt Telescope to create this sky survey, at the time the most advanced sky survey ever. The survey detected objects of a magnitude of +22, one million times fainter than the limits of human vision. The NGS-POSS collection of photographic negative prints was published multiple times through the 1950s-1970s and scanned into the Digitized Sky Survey in the 1990s. The collection includes a set of prints measuring 14x17" from the photograph atlas, as well as a written survey guide and catalog of plates.
