Isaac Newton was the first to really make it work. Newton's reflecting telescope consisted of a single curved main mirror, coupled with a smaller flat mirror positioned at the focal point and ...

Well, any of us who has ever looked through a telescope could say the same, for the two principal types in use today were developed by giants: the refractor by Galileo and the reflector by Newton.

The Newtonian reflecting telescope has been in use for centuries since its invention by Isaac Newton in 1668. Unlike refracting telescopes (whose lenses are very expensive), the Newtonian ...

Nestled in the rolling green hills of the English countryside is an important site in global astronomical history. But now, ...

One of the byproducts of his experiments with light was the Newtonian telescope, still widely used today. Newtonian telescopes use a reflecting mirror to avoid the colour distortion and rainbow ...

His theory of optics made him reconsider the design of the telescope, which up until this point was a large, cumbersome instrument. By using mirrors instead of lenses, Newton was able to create a ...

Credit: Galileo Galilei, 1610 Within sixty years, Isaac Newton had built his own new and improved reflecting telescope with a curved mirror, coated with a fine layer of reflective silver metal ...

His study and understanding of light, the invention of the reflecting telescope (1668), and his revelation in his Principia of the mathematical ordering of the universe are all represented on his ...
