Historical of Telescopes
Telescopes made their mark in the history almost 400 years back in early 1600’s. It all began when Galileo, an Italian mathematician, invented a new mechanical instrument that helped him in realizing his dream of viewing different celestial objects in the sky at night.

According to the principle that was invented by Galileo, a telescope should have an arrangement of two lenses in order to gather more light. the principle is that the two lenses would gather the light and would focus the gathered light to build an image.
