In 1958 the Observatory of Asiago was provided by a first Schmidt 50/40 telescope (spherical mirror of 50 centimetres diameter, correcting plate of 40 centimetres diameter). It was designed by the technicians Galazzi and Rigoni of the Asiago Observatory and realized by Officine Sarti, in Bologna. The Schmidt 50/40 telescope was characterized by a field of 35 square degrees. Almost 6.000 photographic plates were obtained from 1958 untill 1966, when a new, larger Schmidt telescope was realized. This first photographic Archive pointed out the interesting results deriving from a wide field instrument. During its first eight operating years, the astronomers discovered some fifteen supernovę, a lot of variable stars and flares stars.

Stated the high utility of a wide field telescope for the research activities of the Observatory, it was decided to increase the programme for the discovering of variable stars, especially of novae and supernovae. The new Schimdt 92/67 telescope (spherical mirror of 92 centimetres diameter, correcting plate of 67 centimetres diameter) was realized in two years, promoter Leonida Rosino, who was appointed Director of the Observatory of Asiago in 1953. |
