施密特攝星儀
Under Schorr's directorship the optician Bernhard Schmidt got rooms and time to experiment with new optical assemblies. Schmidt constructed several new telescope constructions for the observatory. In 1930 Schmidt invented the Schmidt camera, a telescope with a very wide field of view and free from image elongations in the plate edges far from the optical axis. Schorr urged Schmidt to build the first Schmidt Camera at Bergedorf observatory.
