information about the reflecting telescope?

Answer 1

There's a couple different kinds of reflecting scopes. The best known is the Newtonian, which collects light at a primary mirror at the bottom of the tube and shines it onto a secondary mirror near the top of the tube, which in turn directs the light into and through the eyepeice, where the image is magnified at a factor determined by the focal length of the eyepeice.
There's also Dobsonian scopes, which are just Newtonians with a cheaper and different kind of mount....they're designed to be "more affrdable", but are a bit awkward.
Then there's the Cassegrain scopes, which tend to look thick and stubby in design with the eyepeice at the bottom of the tube, looking a little like a mutant refractor.

Answer 2

Hi. They use a mirror, either spherical or parabolic usually, to gather light and bounce it back towards a secondary mirror and then to an eyepiece. The eyepiece forms the image that you see.
