The "Cavagna Telescope" is the main instrument of the Observatory. It is a Ritchey-Chrétien Astrograph with a structure in Carbon Fiber, produced by RCOS (Ritchey-Chrétien Optical System) and a primary mirror of 50 cm or 20 inch (f/6.8). Mounted on its back a 15 cm (6 inch) refractor and a 17.8 cm (7.2 inch) Maksutov guide telescope (f/15). All these instruments are installed on a robotic german mount developed by the italian 10Micron company.
A small CCD camera connected to the Maksutov telescope is controlled via PC through a software developed to allow useful follow-up of asteroids and comets. The refractor is used for planets or Sun observation during the diurnal session, through a Daystar solar filter coupled with a CCD camera.
An Apogee CCD camera (AP8p model equipped with a 1024*1024 back-illuminated sensor) is connected to the RCOS telescope direct focus(focal lenght of 3411 mm, FOV 24.6 x 24.8 arcmin). In good conditions it is possible to reach magnitude V=22.
