Ritchey-Chretien mirror telescope. Main mirror diameter 75 cm, focal length 600 cm (f:8). Built by Carl Zeiss, Oberkochen in 1976/77. Azimuthal mount, i.e. the telescope has to move in both axes with variable velocity to compensate for the rotation of the earth. This requires a computer control of both axes. Used for direct imaging of galaxies stellar clusters with a CCD camera, especially in the red spectral range.
