The James Gregory Telescope was constructed in 1962 by the University of St Andrews. It is of a Schmidt-Cassegrain design and is fitted with a CCD camera.[1] The telescope has very large field of view, compared even to regular 'wide field' designs, and can view 5 square degrees.[2]
The James Gregory Telescope is the largest working optical telescope in the UK and is still used by the School of Physics and Astronomy for research in collaborative projects such as SuperWASP and the study of super massive black holes and their impact on galaxy structure.[3]
The James Gregory Telescope is named after the Scottish mathematician, astronomer and University academic James Gregory, who invented the design Gregorian telescope.[4] This was the first design for a reflecting telescope, and pre-dates Newton's design; however Newton is better known as he actually produced a functioning example. (see Newton's reflector)
As of 2018, this telescope is recognized as the largest telescope in operation in the United Kingdom.[2] It is also recognized as the largest Schmidt-Cassegrain.[2] This design was developed by Baker and Linfoot, and a half-scale model was also made during its development.[2] It was estimated that the telescope cost about £1 million to manufacture, in early 21st-century currency.[2]
The telescope uses both a mirror and corrector, and is capable up to 16 degrees but was adjusted after it came online in 1962.[2]
The telescope has an aperture of 37 inches, but in the current setup about 33 inches of aperture are used.[5]
