People have been looking at the sky to observe the stars and other celestial objects for centuries. Telescopes have been the most magnificent instruments, not only for the scientists and astronomers, but for any curious person fascinated by deep sky objects and astronomical phenomenon. The development of telescopes helped made possible for almost every human being to be able to view fascinating objects like planets, comets, black holes, quasars and other wonderful objects billions and billions of miles away.

Telescopes come in all shapes, sizes and capabilities depending on their function. Although optical telescopes which uses visible light in electromagnetic spectrum, are the type most commonly used for stargazing and amateur astronomy. Lots of astronomical research is done on telescopes that look at other wavelengths of electromagnetic spectrum Visible light, the light humans see, is in the middle of the range, short wavelengths include gamma rays and X-rays, whereas longer wavelengths include microwaves and radio waves. Telescopes sensitive to these wavelength ranges shows us something unique about the universe and allows us to view events and objects that can’t be seen with human eyes.

Using the information provided in this section you will be able to differentiate between the kinds of telescopes and guide you to pick the best if you are adventurous enough and plan to venture into deep space of our fascinating universe.
