AAA Editor Notes
Palomar Observatory, 4.5 mi. n. on CR S6, consists of four domes; the largest houses the 200-inch Hale telescope, which is used to study distant celestial bodies. Also included is a 48-inch Samuel Oschin telescope and 24-inch and 60-inch reflecting telescopes. These telescopes are used for astronomical research by measuring the physical properties of planets, stars and galaxies.
Temperatures inside the dome can be in the 30s and 40s October through May, so dress accordingly. High heels are not recommended.
Guided tours are available.
