From Wikipedia, the free encyclopedia

The Mount Laguna Observatory or MLO is an astronomical observatory operated by the Astronomy Department of San Diego State University (SDSU). It is located approximately forty five miles east of downtown San Diego on the eastern edge of the Cleveland National Forest, and is named after the Laguna Mountains.

Current Research Projects

The observatory has four telescopes which are used by the students and faculty of both SDSU and the University of Illinois at Urbana-Champaign.


Data is transferred back from the MLO via the High Performance Research and Education Network (HPWREN).


  • 40-inch (1,000 mm) ULTRA telescope (Test bed for special Lightweight Mirrors)
  • 21-inch (530 mm) Buller telescope
  • 24-inch (610 mm) Smith telescope
  • 40-inch (1.0 m) "Illinois" telescope
  • 100-inch (2.5 m) Large robotic telescope (proposed)

Future Equipment and Research Projects

A collaboration between the University of Kansas, Composite Mirror Applications out of Tucson, AZ, and Dartmouth College is currently looking to replace the 16-inch (410 mm) telescope with another 40-inch (1.0 m) telescope using carbon composite technology in a project known as ULTRA.

Also a 100-inch (2.5 m) Large Robotic Telescope is being planned.
