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.

∙ 10y agoThere are many kinds of telescopes, but if you must describe them as only two groups, they are the refracting telescopes and the reflecting telescopes.
Refractor
The Refractor, also known as the dioptrics, is a telescope that uses lenses to refract (bend) the light that it collects. This refraction causes parallel light rays that converge at a focal point at the opposite end, where they can be magnified by an eyepiece.
Newtonian Reflector
The Newtonian Reflector, also known as catoptrics, is a telescope which uses a spherical or concave parabolic primary mirror to collect, reflect and focus the light onto a flat secondary mirror (diagonal). This secondary mirror in turn reflects the light out of an opening in the side of the tube and into an eyepiece for focus and magnification.

- Radio Telescope
- Optical Telescope
- X Ray Telescope
- Gravity Wave Telescope
- Neutrino Telescope
- Lobster Eye Telescope
- Microwave Telescope
- Gamma Ray Telescope
- Thermal/Infrared Telescope
- Space Telescope
- (there are more, this list is not exhaustive)
However in the class of Optical Telescope there are two main designs, Those using mirrors (Reflecting Telescopes) and those using lenses (Refracting Telescopes).

What are the instrument used to study stars and other heavenly bodies?
Telescopes are the main instruments. There are many different types, such as radio telescopes, besides the "usual" optical telescopes. Other instruments such as spectrometers are very useful too.
Why do you use only two types of telescopes here on earth optical or radio telescopes?
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
What are 3 types of energy collected by telescopes?
Three types of energy that are collected by telescopes are Light energy, Mechanical energy and Thermal energy.
How are reflecting and refracting telescopes different?
reflecting telescopes have concave lenses and refraccting telescopes have convex lenses.
Why are different types of telescopes used to observe and study stars?
Fifferent objects in the Univers have different levels of electromagnetic energy. Telescopes that detect different types of electromagnetic waves are able to see the different energy objects objects. For example night vision cameras pick up the infrared radiation of the human body that the normal cameras can't see.
What kinds of problems occur with opticol telescopes?
Optical telescopes are of two types: refractive and reflective. The refractive telescopes have chromatic aberration (huh? different colors are focused in different plains -- huh?). This is less of a problem with reflective telescopes.
Are there different types of telescopes?
Yes.
What were some inventions in the 1600s?
different types of telescopes and the barometer
How many different types of telescopes are there and where would you find them?
298
Are celestron telescopes reflecting telescopes?
They have many other different types of telescopes than just reflecting!!!! I have a refracting telescope myself. They also have other things like binoculars and microscopes
Why might astronomers use different types of telescopes to obtain images in space?
to get every view
What are types of telescopes?
Light telescopes which are refractor and reflector and radio ones.
What are the instrument used to study stars and other heavenly bodies?
Telescopes are the main instruments. There are many different types, such as radio telescopes, besides the "usual" optical telescopes. Other instruments such as spectrometers are very useful too.
Why do you use only two types of telescopes here on earth optical or radio telescopes?
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
Type of telescope?
Different telescopes utilize different parts of the electromagnetic spectrum. Two types of optical telescope are refracting and reflecting. There are also different kinds of radio telescope investigating different bandwidths from the infra red to the untra violet
How does a refracting telescope differ from other types of telescopes?
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.
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.
