Template:Infobox Observatory Template:Location map Table Mountain Observatory (TMO) is an astronomical observation facility operated by NASA's Jet Propulsion Laboratory (California Institute of Technology). It is located in Angeles National Forest near Wrightwood, California. Located 63 kilometers (Template:Convert/round mi) north-northeast of Los Angeles, TMO is part of JPL's Table Mountain Facility (TMF). The larger site hosts a number of non-astronomical projects. The site was first used by the Smithsonian Institution in 1924, which conducted atmospheric, solar, and astronomical observations for many years. JPL took over the lease in 1962.

TMO conducts high-precision astrometric observations to support NASA and international spacecraft mission navigation, confirmation and recovery of Near-Earth objects such as comets and asteroids that may potentially impact the Earth, and technology development.

Instruments

Observing with the 0.6m telescope

• The 1.02 m (Template:Convert/round in) Pomona College Telescope is a Cassegrain reflector built at Pomona College. It first became operation in 1985, and had new mirrors installed in 1996.
• A 0.6 m Ritchey-Chrétien reflector built by Astro Mechanics was installed in 1966. It is attached to an off-axis German equatorial mount.

Former instruments

• A 1.25 m (Template:Convert/round in) reflector previously located at Cloudcroft Observatory was acquired in the late 1980s and became operation in the early 1990s. It was removed from the TMO web site before June 2003.
• A 0.4 m (Template:Convert/round in) Ritchey-Chrétien reflector built by RC Optical Systems was attached to an equatorial mount. It was installed in 2003 and removed from the TMO web site before July 2011. It was housed in the dome where the Schmidt camera was previously located.
• A 0.4 m (Template:Convert/round in) Cassegrain reflector was installed at TMO in 1962. Harvey Mudd College was the main user of this telescope from the 1970s through at least 1991.
• A 0.27 m (Template:Convert/round in) Schmidt camera owned by JPL operated at TMO from 1985 until at least 1991.
• A 5.5 m (Template:Convert/round ft) millimeter wavelength radio antenna was located at TMO from 1970 until at least 1985.
• A radio interferometer with dishes of 4.4 m (Template:Convert/round ft) and 3.0 m (Template:Convert/round ft) became operational at TMO in 1974.
