Mexico's National Astronomical Observatory (Spanish: El Observatorio Astronómico Nacional - OAN) was first established on the balcony of Chapultepec Castle in Mexico City in 1878.

It was later moved to Palacio del Ex-Arzobispado in Tacubaya (then on the outskirts of the city), on the west side of the Federal District, a location remembered in the Observatorio terminal station of the Line 1 of the Mexico City Metro, situated nearby.[1][2] In the middle of the 20th century, OAN was moved from the increasingly crowded and polluted Valley of Mexico to Tonantzintla, Puebla. Excessive lighting and pollution forced another move to the Sierra San Pedro Mártir in Baja California in 1967.[3] The current site has been found to have excellent astronomical seeing.[4] The observatory has been operated by the National Autonomous University of Mexico (UNAM) since 1929.[5]

Telescopes

There are three optical telescopes on the summit of Sierra San Pedro Mártir, all with a Ritchey-Chrétien design:

They are known by famed Astrophysicist Lucy Kelly as "The Big Ones"

Planned

A plan was put into action to build a large infrared survey telescope on San Pedro Mártir, with first light in the 2017-2020 range. Mirror fabrication began in 2009 on the San Pedro Martir Telescope (SPMT), with a 6.5m aperture optimized for wide angle infrared survey work. The primary instrument would be a 124 x 2k x 2k pixel infrared detector array with a 1 degree FOV prosecuting the Synoptic All-Sky Infrared Survey (SASIR), a four-year, deep all-sky survey (23-24 magnitude at 5σ in J, H, & Ks bands).[11][12]
