He invented it in 1668.
Sir Issac Newton
I think he made the reflecting telescope but I'm not sure...sorry
I believe he invented it in 1688, I would double-check just to make sure.
Isaac Newton did not try to make light. He described properties relating to light. He explained the colours of the Rainbow and designed the first reflecting telescope.
The reflecting telescope
Issac Newton was a guy who made gravity and helped Galileo make gravity when he made the telescope I know you are a kid so tell me I have a nerd friend right next to me.
== == Newton did not invent the reflecting telescope. The first reflecting telescope is credited to Niccolò Zucchi in 1616. In 1668, Isaac Newton made significant improvements to the design resulting in a much improved reflecting telescope that still bears his name, the "Newtonian reflector." He did it because the refracting (lens) telescopes of the day suffered severe color aberration. (Different focal lengths of different colours of light resulting in a blurred image because all the colours can't be brought into focus at the same time.) Reflecting telescopes do not suffer from color aberation and Newton's improvements made them effective observing instruments. Although the colour aberration of refractors was partially solved by the invention of the achromatic lens in 1733 Newton's design remains in use to this day.

Yes he made the telescope in 1668
James Gregory was 25 when he published the design of the telescope that has come to be named for him, the Gregorian Telescope. He never build one. The first one built was make by Robert Hooke ten years after the design was published, and after Isaac Newton built his Newtonian Telescope. Both were reflecting telescopes.
Newton invented the reflector telescope in the 1680's.
A telescope that you can make out the colors clear.
