Mount Laguna Observatory (SDSU)

Mount Laguna Observatory (MLO) is at an elevation of 6,100 ft. on the remote eastern edge in the Laguna Mountains. MLO is well protected from the urban lighting of the San Diego metropolitan area. This remoteness, along with the high percentage of clear nights and excellent seeing, makes Mount Laguna one of the best overall observatory sites in the continental United States. MLO has grown to include four well-equipped telescopes, ranging in size from 21- to 50-inches (0.5- to 1.25-meters), which are used for research by the faculty and students.
