The first type of telescope is the refractor telescope,which uses lenses(镜片) to gather light to a focus at the eye piece. The use of lenses helps the telescope have a superior image. A refracting telescope is not as portable as the other two types of telescopes and so you will have...

The first known practical telescopes were refracting telescopes invented in the Netherlands at the beginning of the 17th century, by using glass lenses. Microscope An optical instrument that uses a lens or a combination of lenses to produce magnified images of small objects, especially of objects ...

* The catadioptric telescope which uses mirrors combined with lenses—either in front of the mirror or somewhere within the optical path—to form an image. Radio telescopes Radio telescopes are directional radio antennas that often have a parabolic shape. The dishes are sometimes constructed of a ...
Where the refractor uses lenses, reflector telescopes uses mirrors to collect, focus and magnify light from the distant objects being observed. The reflector replaced the refractor as the most popular choice for astronomers and there a number of different styles available based on the number and arr...
LOOKING IN THE TELESCOPE A story is told that around 400 years ago some children were fooling around in an eye glass shop. They noticed that when they placed lenses one on top of the other, they wer…
These telescopes use a combination of mirrors and lenses in a sealed tube to make the heavens appears closer to the viewer. Like the refractor, this type of telescope usually has the eyepiece at the back of the telescope. Compound Telescope Strengths: ...

The first telescopes built in the early 1600s were very primitive inventions allowing the user to see around 3-times further than the naked eye. It was not too long however, until Italian astronomer Galileo heard about the invention 'that through use of correctly-positioned lenses, allowed peopl...
