Large Binocular Telescope (LBT)
13 Dec 2017



LBT, a pair of identical 8.4m telescopes, are the first of the Extremely Large Telescopes (ELTs.) Its large aperture, high resolution, low thermal background and high sensitivity allows it to detect faint objects far out in space.

RAL Space Involvement ​ 

RAL Space developed algorithms and software for controlling the pointing of the telescope and maintaining the alignment of the two mirrors of this novel telescope design.​


​Main Objectives 
To efficiently and reliably deliver high-quality data to the users of the observatory, thus enabling excellent science at the forefront of astronomy. As the first ELT, LBT's mission was to also experiment and develop a new generation of ELTs.

​Start Date ​ 
​1997, completed and shipped in 2002​


University of Arizona, Italy (INAF: Istituto Nazionale di Astrofisica), Germany (LBTB: LBT Beteiligungsgesellschaft), The Ohio State University, and the Tucson–based Research Corporation representing the University of Minnesota, the University of Virginia, and the University of Notre Dame.
