Telescope

The Observatorio Astronómico Nacional San Pédro Mártir (OAN-SPM) currently has six telescopes with diameters of 2.1 m, 1.5 m, 0.84 m, 0.60 m, 0.50 m, and 0.28 m (2 telescopes with a common mount) which operate in the Sierra de San Pedro Mártir in Baja California in the northwest of Mexico. Although the history of the Observatory goes back to the 1960s, professional activities began at the site in 1971, with the installation of the 1.5 m and 84 cm telescopes. The 2.1 m telescope was inaugurated in 1979. More recently, telescopes working in robotic mode were installed: 0.60 m telescope (BOOTES-5 in 2015), 0.50 m telescope (COATLI in 2016) and the 0.28 m telescope (DDOTI in 2017).

The OAN-SPM 2.1m telescope is the largest optical telescope in México. Its main mirror is fixed in an equatorial Ritchey-Chrétien focus. The telescope has a hyperbolic primary mirror and a hyperbolic secondary mirror. Three focal lengths are available under request in the 2.1 m telescope: f/7.5 (~13.0 "/mm), f/13.5 (~7.15 "/mm) and f/30 (~3.25 "/mm). A recently fully automated instrument rotator is also permanently mounted on the telescope focus. OPTICAM was designed to be installed with an f/7.5 configuration on the 2.1 m telescope as a common-user instrument under the normal rules of operation and management currently in use in the OAN-SPM.
