New Technology Telescope

Inaugurated in 1990 was a 3.5 meter telescope on an arid mountaintop in Chile. It is the first telescope with "active" or computer-assisted optics. A thin, lightweight mirror is kept in shape with a number of actuators beneath. It is owned by the European Southern Observatory and located at La Silla Observatory, Chile.

La Silla Observatory is an astronomical observatory in Chile with eighteen telescopes. Nine of these telescopes were built by the European Southern Observatory (ESO) organisation
