Located on the summit of Mt. Graham, LBTO aspires to be the first of the ELTs and one of the leading 8-m class telescopes. Comprised of privately funded or national institutes and consortiums of universities, the goal of LBTO and its partners is to ensure that its community of users are receiving the highest-quality astronomical data.

On these pages you will find the information needed to prepare for observations or writing proposals and details about the instruments available.

Additional details about the Mt. Graham International Observatory (MGIO) site can be found on the MGIO web pages. Additional technical details about the mechanics and optics of the Large Binocular Telescope can be found on the main LBTO website.
