Originally, the Naturwissenschaftliche Verein Osnabrück had a 30cm Cassegrain mirror telescope in a sliding roof hut on the Kalkhügel in Osnabrück. Between 1986 and 1991 the Sternwarte was built on the Oldendorfer mountain near Melle (25 km east of Osnabrück).

The building and the telescope were financed by donations, subsidies from municipalities and the county and own contributions from the members. First of all, the telescope is used for public tours. The dome has a diameter of 6.50 meters. On the ground floor, the observations can be pre- or post-processed by slide or video-guided tours for about 30 people.

The telescope is a classic Cassegrain system. The main mirror is 60 cm in diameter, the system focal length is 7460 mm, the effective opening ratio f / 12.4. In nights with good seeing, the telescope exhibits excellent images. The optical system was calculated by Lutz Schmadel, optics and tube manufactured by Horst W. Kaufmann, Crailsheim.

The mount was built according to a design and under the direction of Alois Wagner in the BZO Bildungs-Zentrum Osnabrück GmbH and is a classic German mount, both axes of which are driven by stepping motors with Harmonic Drives (by Phytron). The telescope is controlled by a PC, the control program was written by Reinhard Schröder. Coordinates of the observation objects can be taken directly from catalogs (PPM, NGC) or ephemerides (planets, moon) or entered manually. The absolute positioning accuracy over the whole sky is so precise that the observing objects are usually already at the first approach in the field of view of a long-focal eyepiece or the camera.
