A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses.
There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope. A refractor telescope uses a glass lens as its objective. The glass lens is at the front of the telescope and light is bent (refracted) as it passes through the lens. A reflectortelescope uses a mirror as its objective. The mirror is close to the rear of the telescope and light is bounced off (reflected) as it strikes the mirror
Refracting telescope
A refracting telescope uses lenses to gather and focus light, while a reflecting telescope uses mirrors. Reflecting telescopes are often preferred for large astronomical telescopes because mirrors can be made larger and more easily than lenses.
the reflecting telescope was!!
The refracting telescope was invented around 1608 by Dutch eyeglass maker Hans Lippershey.
"I logged onto WikiAnswers, went directly to the Astronomy category, and immediately chanced upon a new question that challenged: 'Use refracting telescope in a sentence' . "
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.

The focus is between the two lenses, closer to the eyepiece
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths

A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]

The main difference between Hubble Space Telescopes and other telescopes is the fact that the Hubble is placed in outer space where it can observe without the distortion of the Earth's atmosphere.
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
