Named for the mountain town and region hosting the largest astronomical observatory on Italian territory. When dedicated in 1942, the 1.2-m telescope was the largest in Europe; a 1.8-m Cassegrain reflector was added in 1973. The observatory has been particularly active in the discovery and photometric and spectroscopic monitoring of all types of variables, including supernovae. A program to discover new minor planets has been conducted with Asiago Schmidts since 1993. (M 30478) _ _.
