The Large Binocular Telescope (LBT) is one of the most advanced optical telescopes in the world, located atop of mt. Graham, a 3200m-high mountain in the Arizona desert.
LBT has been the first to demonstrate the full power of Adaptive Optics, the technique that allows us to eliminate the effects of atmospheric blurring and effectively make the telescope operate as if it was outside the atmosphere.
LBT is the only binocular telescope in the world – it is equipped with two 8.4m mirrors mounted on the same structure. When working in interferometric mode it is equivalent to a 22.4m wide telescope, delivering the sharpest images ever obtained at optical frequencies.

LBT equipped with state-of-the art instruments. You may find full information on its website.

LBT is an international collaboration between US, Italy and Germany.
Italy (through INAF) owns 25% of the telescope shares and observing time.

I am the President of the LBT Corporation (Tucson, Az) and supervise all the activities of the telescope. Enjoy some nice picture of the telescope in the gallery below.
