How does a telescope work?

Question

does anyone know any good websites that have easy to understand information on telescopes? All the ones ive found so far are really hard to understand!
thanks and ten points to best answer!

Answer 1

An optical telescope gathers and focuses light mainly from the visible part of the electromagnetic spectrum (although some work in the infrared and ultraviolet). Optical telescopes increase the apparent angular size of distant objects as well as their apparent brightness. In order for the image to be observed, photographed, studied, and sent to a computer, telescopes work by employing one or more curved optical elements—usually made from glass—lenses, or mirrors to gather light and other electromagnetic radiation to bring that light or radiation to a focal point. Optical telescopes are used for astronomy and in many non-astronomical instruments, including: theodolites (including transits), spotting scopes, monoculars, binoculars, camera lenses, and spyglasses.

Answer 2

Look, people will tell you that it's a child's toy, and in comparison to telescopes some of us have used or built, it is. But it is far better than the naked eye. I would say if you are thinking about a telescope that size, you might consider a pair of binoculars. I don't know what price range you are talking about, but you should be able to find some decent second-hand ones with at least 50 mm lenses for the same price. Check it out on e-bay some time. I have seen lots of them there.

Hello,



(ANS) Try googling "How Stuff works" this site will explain how a telescope works.



**There are x2 main types of telescope and these are a) Refracting telescopes which uses glass lenses and b) Reflecting telescopes that use a series of high quality mirrors.



**ALSO SEE:- last week Richard Hammonds Engineering Connections (of top gear fame) About the making of the worlds biggest telescope the twin KECK telescopes on Mount Mauna Kea in Hawiee. This is also available as a catch up program viewable over the web using the BBC's iplayer. http://www.bbc.co.uk/iplayer/search/?q=%22Richard%20Hammond%22

I have a Konusmotor 500 Semi Automatic reflector telescope with

114 mm aperture and a focal length of 500 mm.

Answer 5

You point one end at something and look through the other end.
