The very first known practical and functional telescope was crude yet ahead of its time. Nowadays, it can refer to a diverse array of devices that can detect electromagnetic field.

It was in the 18th and 19th century wherein silver coated glass mirrors and aluminized mirrors were introduced. In those old days, there were so many limitations and the biggest was the optimum physical limit for the refracting telescopes which is about 1 meter that spurned researchers to develop and innovate one. This century, there is a great development of telescopes that even a child can have a simple one as a toy. There is a wide selection of complex and hi-tech astronomical devices that can be purchased online. Some of these are refracting telescope, reflecting telescope, astronomical telescope, catadioptric telescope, and many others.
