In 1993, he was Italy's first amateur astronomer (and the second discoverer worldwide) to discover a minor planet using a CCD camera. (The first numbered CCD-based discovery was 4255 Spacewatch, which was discovered by the Spacewatch project in 1986).
He also searches for supernovae and is a co-discoverer of SN 1996ae.
The main-belt asteroid 7529 Vagnozzi was named in his honor. Naming citation was published on 11 April 1998 (M.P.C. 31611).
