Within a few decades, the reflecting reach was invented, which used mirrors.

Main expression: Op! tical telescope An optical telescope gathers and focuses light chiefly from the visible part of the electromagnetic spectrum (although some work in the infrared and ultraviolet).[9] Optical telescopes increase the spare angular size of it of distant objects as well as their apparent brightness.
