Images from the Second Palomar Observatory Sky Survey (POSS II)

The Second Palomar Observatory Sky Survey (POSS II) by the 48-inch Samuel Oschin Telescope produced some of the most iconic astronomical images of all time. The POSS II plates were digitized as part of the STSci Digital Sky Survey (DSS) and are available online to anyone from the DSS site. Enthusiasts, such as Sky Factory and Light Figures, have reprocessed the images using modern techniques to produce spectacular digital views of deep sky objects.
