Re-opening for public tours and programming began May 27, 2022.
A refracting telescope is a type of optical telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses. Although large refracting telescopes were very popular in the second half of the 19th century, for most research purposes, the refracting telescope has been superseded by the reflecting telescope, which allows larger apertures. A refractor's magnification is calculated by dividing the focal length of the objective lens by that of the eyepiece.
The Digitized Sky Survey (DSS) is a digitized version of several photographic astronomical surveys of the night sky, produced by the Space Telescope Science Institute between 1983 and 2006.
The Giant Magellan Telescope (GMT) is a ground-based extremely large telescope under construction at Las Campanas Observatory in Chile’s Atacama Desert. Commissioning is anticipated in the late 2020s. It will consist of seven 8.4 m (27.6 ft) diameter primary segments, that will observe optical and near infrared (320–25000 nm) light, with the resolving power of a 24.5 m (80.4 ft) primary mirror and collecting area equivalent to a 22.0 m (72.2 ft) one, which is about 368 square meters. The telescope is expected to have a resolving power 10 times that of the Hubble Space Telescope and four times that of the James Webb Space Telescope, although it will be unable to image in the same infrared frequencies available to telescopes in space. As of May 2021, six mirrors have been cast and the construction of the summit facility has begun.
The Florence and George Wise Observatory is an astronomical observatory owned and operated by Tel Aviv University. It is located 5 kilometers west of the town of Mitzpe Ramon in the Negev desert near the edge of the Ramon Crater, and it is the only professional astronomical observatory in Israel.
Pine Mountain Observatory (PMO) is an astronomical observatory owned and operated by University of Oregon Department of Physics. The facility is located 26 miles (42 km) southeast of Bend, Oregon (USA) in the Deschutes National Forest near the summit of Pine Mountain.
Sommers–Bausch Observatory is an astronomical observatory located on and owned by University of Colorado Boulder. The building was initially completed in 1953 and named after Elmer E. Sommers and Carl L. Bausch.
Moore Observatory is an astronomical observatory owned and operated by University of Louisville. It is located on the Horner Wildlife Refuge in Oldham County, Kentucky (USA) approximately 20 kilometers (12 mi) northeast of Louisville. It opened in 1978, and was dedicated to Walter Lee Moore, a Professor of Mathematics at U of L from 1929 to 1967.
The Thirty Meter Telescope (TMT) is a planned extremely large telescope (ELT) that has become controversial due to its location on Mauna Kea, on the island of Hawaiʻi. The TMT would become the largest visible-light telescope on Mauna Kea.
Las Cumbres Observatory (LCO) is a network of astronomical observatories run by a non-profit private operating foundation directed by the technologist Wayne Rosing. Its offices are in Goleta, California. The telescopes are located at both northern and southern hemisphere sites distributed in longitude around the Earth. For some astronomical objects, the longitudinal spacing of telescopes allows continuous observations over 24 hours or longer. The operating network currently consists of two 2 meter telescopes, nine 1 meter telescopes, and seven 40 cm telescopes, placed at six astronomical observatories. The network operates as a single, integrated, observing facility, using a software scheduler that continuously optimizes the planned observing schedule of each individual telescope.
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.
DFM Engineering is an American telescope and optics manufacturer founded in 1979 by Frank Melsheimer in Longmont, Colorado. DFM makes medium size Cassegrain telescopes and their associated systems including telescope optics, control systems, and mounts. A range of pre-designed telescopes are made, as are various custom installations. DFM produces its classical Cassegrain design in various apertures from 16 inches (0.4 m) to 50 inches (1.3 m) and larger. The base DFM 16-inch (40 cm) telescope system cost roughly 94 thousand USD in 2005.
LightBuckets is a commercial astronomical observatory formerly located in Rodeo, New Mexico and now located in France, which rents time on its telescopes to customers around the world via a website on the Internet, including amateur and professional astronomers. It is an online astronomy platform with live-views, and hosts an image gallery of astronomy images. Recognized scientific uses include the confirmation of supernova and discovery of asteroids.
The SUNY Oneonta College Observatory is an astronomical observatory in Oneonta, New York. The observatory is home to the largest optical telescope in New York: a 1-meter Newtonian reflector. It is also believed to be the one of the largest telescopes open for public observing east of the Mississippi. The telescope was constructed by JMI Telescopes of Lakewood, Colorado.
The Meade LX200 is a family of commercial telescopes produced by Meade Instruments launched in 1992 with 8" (20.32 cm) and a 10" (25.4 cm) Schmidt–Cassegrain models on computerized altazimuth mounts. Two larger models, a 12" (30.48 cm) and a 16" (40.64 cm), quickly followed. The original version was later informally named the "classic" LX200 as newer upgraded versions replaced it. The first of these was the LX200GPS, which featured global positioning system electronics. A 360 mm (14 in) LX200GPS was later added to the line.
The Westerlund telescope was inaugurated in 2004. and is named after Bengt Westerlund (1921–2008). The telescope belongs to Uppsala Astronomical Observatory and serves as a training telescope. It is used in courses for undergraduates, graduates, and examination projects as well as ordinary astronomical observations by astronomers at the observatory.
