Online Repository of Raw Astronomical Data

Welcome to RSDAO data center provided by Torun Centre for Astronomy, Nicolaus Copernicus University, Torun, Poland.

The Astronomical Observatory of the Nicolaus Copernicus University in Piwnice near Toruń, founded in 1947, collected about 12,000 historical photographic plates containing the results of astronomical observations fixed on photosensitive materials (on glass plates and celluloid films). These materials were collected by astronomers from the NCU in the period from the IIWW to the 1990's using optical telescopes in the observatory: the historic Draper's astrograph, 90 cm Schmidt-Cassegraine Telescope with prisms (TSC) or Copernicus Canadian Spectrograph (CCS) and so-called small Schmidt Camera (KS) with objective prism. They are initiated by prof. Władysław Dziewulski and prof. Wilhelmina Iwanowska, original and unique research achievements of several generations of astronomers from Toruń. Photographs of sky recorded on films are a very rich source of valuable astronomical data of a timeless value that can be used in research by Polish and international scientific teams.
