The Newtonian telescope, also called the Newtonian reflector or just a Newtonian, is a type of reflecting telescope invented by the English scientist Sir Isaac Newton, using a concave primary mirror and a flat diagonal secondary mirror. Newton's first reflecting telescope was completed in 1668 and is the earliest known functional reflecting ...
The first reflecting telescope built by Sir Isaac Newton in 1668 [3] is a landmark in the history of telescopes, being the first known successful reflecting telescope. [ 4 ] [ 5 ] It was the prototype for a design that later came to be called the Newtonian telescope .
Notes on Hans Lippershey's unsuccessful telescope patent in 1608. The first record of a telescope comes from the Netherlands in 1608. It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October 1608 for his instrument "for seeing things far away as if they were nearby." [12] A few weeks later another Dutch instrument-maker ...
A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic ...
Sir Isaac Newton (/ ˈ nj uː t ən /; 4 January [O.S. 25 December] 1643 – 31 March [O.S. 20 March] 1727) [a] was an English polymath active as a mathematician, physicist, astronomer, alchemist, theologian, and author. [5] Newton was a key figure in the Scientific Revolution and the Enlightenment that followed. [6]
In 1668, Isaac Newton built the first practical reflecting telescope, of a design which now bears his name, the Newtonian reflector. [10] The invention of the achromatic lens in 1733 partially corrected color aberrations present in the simple lens [11] and enabled the construction of shorter, more functional refracting telescopes.

New measurements from the Webb telescope – Nasa’s most powerful space observatory – could help explain one of the deepest mysteries of the cosmos, according to the researchers behind them.
The telescope's first light (first, first light) occurred in 1965, and it was dedicated in 1967. [11] [12] On December 1, 1967, the Isaac Newton Telescope of the Royal Greenwich Observatory at Herstmonceux was inaugurated (dedicated) by Queen Elizabeth II. [13] [14] [12] One of the accomplishments with the telescope was the observations of ...
