What is another word for Gregorian Telescope?
Pronunciation: [ɡɹɛɡˈɔːɹi͡ən tˈɛlɪskˌə͡ʊp] (IPA) 
The Gregorian Telescope was so named after its inventor, James Gregory. This telescope design employs a concave mirror to collect and reflect light to a smaller secondary mirror, which then sends light through a hole in the primary mirror to the eyepiece. While the name "Gregorian Telescope" is commonly used, there are also several synonyms to describe this type of telescope design. These include the "Gregorian reflector," which emphasizes the use of a mirror to reflect light, and the "Concave Cassegrain," named after another type of telescope design that also uses a concave primary mirror. Regardless of the name used, the Gregorian Telescope design remains a popular and effective method for studying the cosmos.
