This service provides FITS images of the science area of the plates as well as images of the entire plates, including previous markings. 1963ASPL....9...89L Astrophysikalisches Observatorium Potsdam (42) 80cm Great Refractor Zeiss Triplet 15 cm Potsdam-Telegrafenberg Optical /hppunion/q/im/info \RSTccby{Kapteyn series plate scans} Support for scanning the plates and obtaining metadata was provided by DFG grant STE 710-6-1.
