Anderson Mesa Station is anastronomicalobservatory established in 1959 as adark-sky observing site forLowell Observatory. It is located atAnderson Mesa inCoconino County,Arizona, about 12 miles (19 km) southeast of Lowell's main campus on Mars Hill inFlagstaff, Arizona.

• The 1.83 m (72 in) Perkins Telescope is shared withBoston University (BU) andGeorgia State University.^[1] Built in 1931 byWarner & Swasey Company, it was originally located at thePerkins Observatory ofOhio Wesleyan University (OWU) inDelaware, Ohio.^[2][3] It was moved to Anderson Mesa in 1961, and was purchased by Lowell in 1998. Lowell and BU formed a partnership to operate the telescope that year, and GSU joined later.^[4] The original 69-inch mirror, which wasfigured byJ. W. Fecker, Inc., was the largest single piece of glass ever cast in America when it was poured.^[2] It was replaced in 1965 with the current mirror made of Duran-50low-expansion glass.^[5][6]
• The 1.07 m (42 in) John Hall Telescope was built by AstroMechanics and installed at Anderson Mesa in 1970.^[7] It was named after former Lowell Observatory director John S. Hall in 1990.^[8] In 2004, theRitchey-Chrétien telescope was upgraded with a new mirror fromHextek, and with other parts.^[9]
• The 0.79 m (31 in) telescope of theNational Undergraduate Research Observatory (NURO) was built by AstroMechanics and installed in 1964 at Anderson Mesa by theU.S. Geological Survey (USGS) forProject Apollo.^[10] It was purchased by Lowell in 1972, and refurbished in 1990.^[8][11] It is used by the NURO consortium for up to 60% of the time, and by Lowell scientists.
• TheNavy Precision Optical Interferometer (NPOI) is collaboration ofLowell Observatory, theU.S. Naval Observatory (USNO)Flagstaff Station (NOFS), and theU.S. Naval Research Laboratory (NRL).^[12] Construction on the facility began in 1992, and engineering tests began in 1994. The first images were acquired in 1996.^[13]

• The 0.6 m (24 in)Lowell Observatory Near-Earth-Object Search (LONEOS)Schmidt camera was used to search forasteroids and othernear-earth objects. It was built by J. W. Fecker, Inc. in 1939, given toPerkins Observatory in the 1950s, and purchased by Lowell in 1990.^[8] Starting in 1992 it was refurbished, and saw first light in the dome that previously held the Lowell Astrograph in 1997.^[14] Use of the telescope ended along with the LONEOS project in 2008.
• The 0.33 m (13 in) Abbot L. Lowell Astrograph, also known as the Pluto Discovery Telescope and informally as the Pluto Camera, is anastrograph built byAlvan Clark & Sons in 1929. In 1930 it was used byClyde Tombaugh to discoverPluto.^[15] In 1971, it was moved a new building at Anderson Mesa, and returned to Mars Hill in 1992.^[16][17]
