Large Binocular Telescope, Double optical telescope at Mount Graham, Arizona, United States
The Large Binocular Telescope contains two primary mirrors of 8.4 meters each, mounted on the same structure at 3221 meters elevation.
Construction of this telescope started in 1996 and completed in 2004, facing multiple legal challenges from environmental groups and indigenous communities.
The Mount Graham location generated concerns among San Carlos Apache Tribe members who consider the mountain a sacred site for their traditional practices.
The telescope's advanced adaptive optics system produces images with higher resolution than the Hubble Space Telescope in specific wavelengths of light.
This telescope combines light from both mirrors to achieve the observing power equivalent to a single 22.8-meter telescope when operating in interferometric mode.
