Abstract
The Italian Galileo telescope (TNG) belongs to a new generation of intermediate-sized telescopes (3.5 meters primary mirror) constructed with the aim of optimizing the operating conditions of the scientific instrumentation through a dedicated active-optics system.
It will be operated at the Roque de Los Muchachos Observatory (ORM, Canary Islands). The telescope’s first light is foreseen for the second half of 1997, while the instrumentation’s first light is foreseen for the first half of 1998, when the first instrument’s field derotator will be available at one of the two Nasmyth focal stations.
This paper describes the main concepts involved in active optics telescope design, its implementation in TNG, and the first results obtained during the optics qualification tests and the mirror support tests.
