Space Surveillance and Tracking
ADS built for INAF-OAS Bologna the Tandem instrument installed on the G.D. Cassini telescope at Loiano observatory. Tandem was conceived and designed by professor A. Buzzoni.
Tandem is made by four f/3 Newtonian telescopes, each one featuring:
350 mm aperture
resolution of 1.75 arcsec/pixel (9 um pixel size)
field of view (FOV) of 2°x2° with a 4-inch Wynne corrector.
STEERABLE TELESCOPES STATION (STS)
The main feature of our multiple telescope system is that each telescope can be oriented in two angular directions independently of the others, on a common equatorial mount. Thus the array can be used at its maximum depth in magnitude by converging the four telescopes on the same 2°x2° FOV or, alternatively, fully exploiting the wider angular coverage on the sky by orienting each telescope to obtain a mosaic of four adjacent fields, covering a 4°x4° FOV.
