Resource Description:
In the context of Kapteyn's plan to obtain a photometric standard, in Potsdam more than 400 photographic plates of several Selected Areas, Special Areas, and Kapteyn-Pritchard areas were obtained between 1910 and 1933, both as direct images and with an object prism. This service provides FITS images of the science area of the plates as well as images of the entire plates, including previous markings.
