What telescope collects light with a mirror?

The type of telescope is called a reflector. There are multiple subtypes of reflectors like a dobsonian, newtonian, RC, etc. Check out my youtube video on how to work with pictures taken from a telescope. youtu.be/M7-vLeVhM9g


How is the image projected through a telescope?

The main lens or mirror produces a virtual image of the obect being looked at, and it occurs at a distance behind the lens (or in front of the mirror) equal to the focal length. The telescope also has an eyepiece whose function is to allow the oberver to see the virtual image. Many telescopes come with a range of different eyepieces that give different amounts of magnification.


Do refracting and reflecting telescopes use visible light to view the images?

Those terms are most commonly used for optical telescopes. However, the same design can be used for non-visible frequencies; for example, radio telescopes of the "satellite dish" variety are essentially reflecting telescopes.


What does the light gathering ability of a telescope depend on?

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.


What kind of telescope's objective is a lens but contains no mirrors?

Refractors use a concave lens to refract the light rays through the main body, off the rectangular prism and into the eyepiece. These telescopes use no mirrors like reflectors (except the triangular prism contains a small mirror but a triangular prism is optional)

What is catadioptric telescope?

Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.

What are some telescopes names?

The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.


Is a light telescope the same as a refracting telescope?

Not exactly. A light telescope is a telescope that catches and shows visible light. The main light-gathering piece may either be a lens, in which case you would have a refracting telescope. Or - much more common with the larger telescopes - the main light-gathering piece is a parabolic mirror. In this case, it is a reflecting telescope. The largest refracting telescope is about 1.2 meters in diameter; all larger telescopes - currently up to about 8 meters - are parabolic mirrors.

Does a telescope form a real image?

Yes. Both the objective lens in a refracting telescope and the main mirror in a reflecting telescope form real images at the prime focus. A frame of photo film or a CCD placed at that spot will capture the image.


What makes The Hubble Space Telescope different from other telescopes?

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.


What is the meaning of refracting telescope?

That means that it uses lenses that use refraction to change the direction of light. More specifically, the main light-gathering piece is a lens - as opposed to a reflecting telescope, which uses mirrors for this same purpose.

What are two different types of telescopes?

Refractors and reflectors. One should add the largely Russian-developed Cassegrainean combines features of both systems-called also Maksutov after its Russian inventor who was awarded the Staliln Prize for this feat. They are adapted to (Mirror=Lens) telephoto camera lenses, also.
