The Cerro Tololo Inter-American Observatory (CTIO) is an astronomical observatory located on Cerro Tololo in the Coquimbo Region of northern Chile, with additional facilities located on Cerro Pachón about 10 kilometres (6.2 mi) to the southeast. It is within the Coquimbo Region and approximately 80 kilometres (50 mi) east of La Serena, where support facilities are located.

Construction of large buildings on Cerro Tololo ended with the completion of the Víctor Blanco Telescope in 1974, but smaller facilities have been built since then. Cerro Pachón is still under development, with two large telescopes inaugurated since 2000, and one in the early stages of construction.

Stull Observatory is an astronomical observatory owned and operated by Alfred University. Named after Dr. John Stull, who helped establish the observatory in 1966, it is located in Alfred, New York (USA). It is notable for housing seven independently housed telescopes ranging in size from 8 to 32 inches. The largest, the Austin-Fellows 32 inch Newtonian Reflector is tied with the Vassar College Class of 1951 Observatory for the rank of second largest optical telescope in New York state after the 40 inch telescope at SUNY Oneonta College Observatory. Telescopes at the observatory are regularly opened to the public. The observatory is also used for those pursuing a minor in astronomy or a concentration in astrophysics.
Martz Observatory is a public, not-for-profit organization devoted to the amateur astronomer. The emphasis of the association is observational astronomy, well-rooted in public education and enjoyment of the starry skies. It was founded by, and eventually named after, Marshal Martz, an amateur astronomer from Jamestown, NY who built the first large telescope ever used at the observatory.

The site and the 30 acres surrounding it were conveyed to the Federal Aviation Administration, which tore down the observatory building and replaced it with a radar installation.
Tortugas Mountain Observatory (TMO) is an astronomical observatory owned and operated by New Mexico State University (NMSU). It is located on Tortugas Mountain, also known locally as 'A' Mountain, in southern New Mexico (USA), approximately 8 kilometers (5.0 mi) southeast of Las Cruces and 4 kilometers (2.5 mi) east of the NMSU campus. Founded in 1963 under the supervision of Clyde Tombaugh, the observatory focused on observing the planets. Much of the information captured at TMO is now available through the Planetary Data System's Atmospheres Node, which is managed by NMSU. The two-dome observatory building was completed in 1964, though observing began with one of the telescopes in 1963. A second building, with a larger single dome, was completed at the opposite end of the ridgeline of Tortugas Mountain in 1967. Regular use of TMO ceased in 1999 or 2000, but the observatory equipment was not dismantled. In 2008 it was used for the Lunar CRater Observing and Sensing Satellite project. In 2010, efforts to revive the observatory for use by the American Association of Variable Star Observers began. As of 10 June 2011, work on project was reported to be 60-75% done.

It was assigned to the Sternberg Astronomical Institute (GAISh) until the collapse of the Soviet Union. The observatory is a state-owned scientific institution that belongs to the Astrophysical Institute after V.G. Fesenkov. It is often used for photometric investigations of variable stars in the Milky Way, eclipsing systems.
