Boyden Observatory is an astronomical research observatory and science education centre located in Maselspoort, 20 kilometres (12 mi) north-east of the city of Bloemfontein in Free State, South Africa. The observatory is managed by the Physics Department of the University of the Free State (UFS). The Friends of Boyden assist the observatory as a public support group, organising open evenings and protecting its public interest. Boyden also makes use of members of ASSA Bloemfontein Centre, the amateur astronomy club of the city, for presenters and telescope assistants.
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. The site was identified by a team of scientists from Chile and the United States in 1959, and it was selected in 1962. Construction began in 1963 and regular astronomical observations commenced in 1965. 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.
A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations. The design was invented by Bernhard Schmidt in 1930.
The Institute of Astronomy (IoA) is the largest of the three astronomy departments in the University of Cambridge, and one of the largest astronomy sites in the UK. Around 180 academics, postdocs, visitors and assistant staff work at the department.

The Maksutov is a catadioptric telescope design that combines a spherical mirror with a weakly negative meniscus lens in a design that takes advantage of all the surfaces being nearly "spherically symmetrical". The negative lens is usually full diameter and placed at the entrance pupil of the telescope. The design corrects the problems of off-axis aberrations such as coma found in reflecting telescopes while also correcting chromatic aberration. It was patented in 1941 by Russian optician Dmitri Dmitrievich Maksutov. Maksutov based his design on the idea behind the Schmidt camera of using the spherical errors of a negative lens to correct the opposite errors in a spherical primary mirror. The design is most commonly seen in a Cassegrain variation, with an integrated secondary, that can use all-spherical elements, thereby simplifying fabrication. Maksutov telescopes have been sold on the amateur market since the 1950s.
The Schmidt–Cassegrain is a catadioptric telescope that combines a Cassegrain reflector's optical path with a Schmidt corrector plate to make a compact astronomical instrument that uses simple spherical surfaces.
Celestron is a company based in Torrance, California, United States, that manufactures telescopes and distributes telescopes, binoculars, spotting scopes, microscopes, and accessories manufactured by its parent company, the Synta Technology Corporation of Taiwan.
The Orange County Astronomers (OCA) is a 501(c)(3) non-profit, civilian-led astronomy organization in Orange County, southern California. It was formed in 1967 and currently operates with around 800 concurrent members; they offer beginner courses in astronomy, and have meetings on the second Friday of every month at Chapman University. Currently, the OCA offers a dark-sky site to viewers, which includes a 22-inch Schmidt-Cassegrain telescope and public-use observation areas. In addition, the OCA has been registered as an affiliate of the Astronomers Without Borders program since March of 2012.

The Hirsch Observatory is an astronomical observatory at Rensselaer Polytechnic Institute (RPI) in Troy, New York. It is located on the roof of the Jonsson-Rowland Science Center and is used by members of the Rensselaer Astrophysical Society as well as astronomy students in laboratory exercises. It is frequently opened to the community for public viewing sessions. The observatory's main dome contains a 16" Cassegrain Reflector, with a CCD camera and fully computerized controls. The observatory also owns a variety of smaller scopes and a SBIG Spectrograph. The spectrograph has been used to catalog bright solar spectrum as part of an effort to create an online digital database for astrophysical research. The current director of the observatory is Professor Heidi Newberg.
The Mills Observatory in Dundee, Scotland, is the first purpose-built public astronomical observatory in the UK. Built in 1935, the observatory is classically styled in sandstone and has a distinctive 7 m dome, which houses a Victorian refracting telescope, a small planetarium, and display areas. The dome is one of two made from papier-mâché to survive in the UK, the other being at the Godlee Observatory.

Based in Invercargill at the southern tip of New Zealand's South Island, its small, active group of about 36 amateur astronomer members participate in a variety of astronomical activities including education with groups and school children, deep sky observing, astrophotography and aurora observation.
Bayfordbury Observatory is the University of Hertfordshire's astronomical and atmospheric physics remote sensing observatory, and one of the largest teaching observatories in the UK. It is located in the relatively dark countryside of Bayfordbury, Hertfordshire, 6 miles from the main university campus in Hatfield. The first telescope was built in 1969, and since then has been used as a teaching observatory for undergraduate students, staff and student research as well as for public outreach activities.
