Refracting telescope. A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses.

The Gran Telescopio Canarias (GranTeCan or GTC) is a 10.4 m (410 in) reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma, in the Canary Islands, Spain. It is the world's largest single-aperture optical telescope. [1] Construction of the telescope took seven years and cost €130 million.
The James Lick Telescope is a refracting telescope built in 1888. It has a lens, which is 91 centimetres (36 in) in diameter—a major achievement in its day. The instrument remains in operation and public viewing is allowed on a limited basis. Also called the "Great Lick Refractor" or simply "Lick Refractor", it was the largest refracting ...
The Vera C. Rubin Observatory, formerly known as the Large Synoptic Survey Telescope (LSST), is an astronomical observatory under construction in Chile. Its main task will be carrying out a synoptic astronomical survey, the Legacy Survey of Space and Time. [11][12] The word "synoptic" is derived from the Greek words σύν (syn "together") and ...
Telescope controls of the 40 in (100 cm) refractor. Yerkes Observatory (/ ˈjɜːrkiːz / YUR-keez) is an astronomical observatory located in Williams Bay, Wisconsin, United States. The observatory was operated by the University of Chicago Department of Astronomy and Astrophysics [2][3] from its founding in 1897 until 2018.
The first large telescope to use the design was the James Gregory Telescope of 1962 at the University of St Andrews. As of 2021, the James Gregory Telescope is also recognized as the largest Schmidt-Cassegrain. [4] The telescope is noted for its large field of view, up 60 times a full moon. [4]
Sketch of Harvard's Great Refractor telescope. In 1839, the Harvard Corporation voted to appoint William Cranch Bond, a prominent Boston clockmaker, as "Astronomical Observer to the University" (at no salary). This marked the founding of the Harvard College Observatory. HCO's first telescope, the 15-inch Great Refractor, was installed in 1847. [3]
