Mount Laguna Observatory

Mount Laguna Observatory is an astronomical facility nestled in the Laguna Mountains at 1859 meters elevation within Cleveland National Forest. The site hosts several research telescopes designed for different types of celestial observations and scientific investigations.

The observatory was established in 1968 by the San Diego State University Department of Astronomy and marked a major advancement in the region's research capabilities. This founding allowed local researchers to participate in modern astronomical studies.

The facility maintains partnerships with multiple universities, including the University of Illinois and University of Kansas, fostering collaboration in astronomical research and education.

The facility sits roughly 75 kilometers east of San Diego and offers excellent observing conditions due to its elevation and remote location. Most nights provide relatively clear skies with minimal light pollution from distant urban areas.

The observatory houses the EvryScope, a specialized survey telescope with multiple apertures that captures large expanses of sky. This instrument enables continuous monitoring of wide areas of the night sky and contributes to various research projects.
