LBTO Science Operations




Welcome to the Science Operations Web Pages for the Large Binocular Telescope Observatory (LBTO), an international collaboration among institutions in the United States, Italy and Germany. LBT Corporation partners are: The University of Arizona on behalf of the Arizona university system; Istituto Nazionale di Astrofisica, Italy; LBT Beteiligungsgesellschaft, Germany, representing the Max-Planck Society, the Astrophysical Institute Potsdam, and Heidelberg University; The Ohio State University, and The Research Corporation, on behalf of The University of Notre Dame, University of Minnesota and University of Virginia. 

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.
