The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses.
Great refractor refers to a large telescope with a lens, usually the largest refractor at an observatory with an equatorial mount. The preeminence and success of this style in observational astronomy defines an era in modern telescopy [ 1] in the 19th and early 20th century. [ 1] Great refractors were large refracting telescopes using ...
