Isaac Newton invented the reflecting telescope.

Newton did not invent the telescope, he invented the reflecting telescope. The reflecting telescope was a major improvement over the distorting refracting telescope.

It is a reflecting telescope

A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.

A Reflecting telescope has a lot of zooming technologies and the High Power telescope is highly powered.
