The largest telescope in Southern California is the Gran Telescopio Canarias (GTC), located at the Roque de los Muchachos Observatory on La Palma in the Canary Islands. However, if you're referring to ground-based telescopes in Southern California itself, the Hale Telescope at the Palomar Observatory is one of the largest, with a mirror diameter of 200 inches (5.1 meters). Palomar Observatory is situated in San Diego County and is renowned for its contributions to astronomy.
