Our Telescope


The Vatican Advanced Technology Telescope in Arizona is a multi-million dollar astronomical research complex paid for by private donations.  It consists of two parts: the Alice P. Lennon Telescope and the Thomas J. Bannan Astrophysics Facility.  The telescope's 1.8-meter (72 inch), f/l.0 mirror was fabricated at the Steward Observatory Mirror Laboratory using revolutionary spin-casting and polishing technologies that are now making giant telescopes possible at considerable cost savings.  The Vatican Observatory Research Group (VORG) operates the telescope in southeastern Arizona where sky conditions are among the best in the world and certainly the Continental United States.

Tours of Mount Graham International Observatory, including the VATT, are run on Saturdays from mid-May to mid-October (weather-permitting) from Discovery Park in Safford, AZ.
