How Does A Telescope Work?

Telescopes are generally of two types. One is a refractor telescope, which uses a glass lenses and the other is a reflector telescope which uses a mirror instead.

The telescope has a simple way of working. The refractors or the reflectors gather a lot of light from an object that is placed far away and brings that object into the focus point. The other way is to use an eyepiece lens that collects the light from the object that is in focus and magnifies it, to take a huge portion of the retina. This principle is exactly the same method that a magnifying lens uses. In short, when the objective lens and the eyepiece are put together, you have a telescope working. The bottom rule is to collect as much as light from the object inside the telescope. However, this light collection method, depends on the diameter of the lens-the aperture.

There are actually many more than just a refracting and reflecting telescope. There are also many diffrent types that can remake an image to be diffrent but most people use more than one to see how the image is proccessed.
