Main mirror diameter 40 cm, corrector plate 25 cm, focal length 90 cm (f:3.6). Built 1963 in the LSW workshop. The large field of view (4 degrees) allow the survey of large fields and, in connection with an objective prism, the simultaneous exposure of numerous stellar spectra, in particular for the purpose of spectral classification.
