A brief history of the telescope. The history of the telescope began in 1608 with a Dutch group of spectacles, who simultaneously created the first functional models of telescopes. The first, however, came about thanks to Hans Lippershi, a German-born manufacturer of lenses and lens sharpeners who first managed to obtain a patent for a telescope.

What is inside the telescope?

In a telescope, the light hits the main lens first. Primary lenses are round and convex and can bend captured light and direct it to the secondary focus lens. This second lens is responsible for focusing that light to create a clear image of the subject.

Is a reflection telescope better than a refraction telescope?

Refractive telescopes are most useful in astronomy because they provide clear vision at long distances, while refractive telescopes are designed for everyday applications such as camera lens systems. To be fair, the reflex and refractive telescopes are handy and useful.
