The Guillermo Haro Observatory (Spanish: Observatorio Astrofísico Guillermo Haro - OAGH) is an astronomical observatory owned and operated by the National Institute of Astrophysics, Optics and Electronics (Spanish: Instituto Nacional de Astrofísica, Óptica y Electrónica - INAOE) in the Mexican state of Sonora. It is located 13 km (8.1 miles) north of Cananea and 85 km (53 miles) south-east of Mount Hopkins. It is named after Professor Guillermo Haro.
The main telescope at the observatory is Ritchey-Chretein design with a 2.12 m (83 in) primary mirror and a 0.5 m (20 in) secondary mirror. Four different instruments are available to be mounted at the Cassegrain focus.[1] Planning for the telescope began in 1972, but it was not dedicated until 1987. Routine operations began in 1992.[2][3]
The observatory has a 0.41 m (16 in) Schmidt-Cassegrain reflector built by Meade Instruments on an equatorial mount located in a separate dome.[4] It is used to make atmospheric extinction measurements and to monitor light pollution.[5]
