The 60cm telescope was officially established in November 1936, through a bequest by Mrs. Merlani, in honour of her late husband, Adolfo Merlani, who had formerly donated one hectare of land to the University in order to build a new observatory. This telescope, built by Zeiss of Jena, has always operated since then, except for a short period in the years 1944-1945. The mirror was the largest in Italy until the 1.2 m Asiago telescope and 1m Merate telescope were built. After the optical tests, the mirror was classified as “one of the best” for its optical characteristics.

The telescope was built following the most modern techniques of that period, and was dedicated essentially to photography, as were all telescopes at that time. In the years around 1960, it was converted into a photometric telescope. More recently, the optics have been converted to a Cassegrain system with the same focal ratio as the 152cm telescope. At present, the telescope is equipped with a five-colour photometer and a new Marconi CCD (series 4710) with 1055×1020 pixels; the pixel size is 13μm.
