What is Telescope?

A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope.

Frequently Asked Questions

Which are the 3 types of telescopes?

Most telescopes will fall into one of three categories: refractors (which use lenses to bend light into focus), reflectors (which use mirrors that reflect light into focus), and catadioptric or compound scopes, (which use a combination of both lenses and mirrors).

What are the 4 main types of telescopes?

Types of Telescopes

  • Refractor Telescopes.
  • Reflector Telescopes.
  • Dobsonian Telescopes.
  • Maksutov-Cassegrain Telescopes.

What are the three main uses of telescopes?

There are three basic functions of a telescope (at least those used by most amateurs) – light gathering, resolving, and magnifying. Light gathering power is a measure of how much light the objective (primary mirror in a reflector, lens in a refractor) can collect from distant objects.

What is the most common type of telescope used?

The two most common designs in the hobby market are the Schmidt-Cassegrain telescope, SCT, and the Maksutov-Cassegrain telescope, MCT. They both have a front corrector plate, which is a lens, a rear primary mirror with a hole in the center, and a secondary reflector which is usually attached to the corrector plate.

What are the advantages of a telescope?

Some advantages of telescope:

  • Elaborate view of the galaxies, planets, stars and other heavenly bodies is possible with the help of telescopes.
  • Camera can be attached for taking photograph for the celestial objects.
  • Telescope can be viewed even with the low intensity of .

What is the importance of the telescope?

telescope, device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.

Which telescope can see galaxies?

Here is a list of some of the best telescopes for viewing planets and galaxies:

  • Celestron Speciality Series Travel Scope 70 Telescope.
  • Pullox 175X 262X 350X Malty Power Reflector Astronomical Reflecting Telescope.
  • Celestron AstroMaster 70AZ Telescope.
  • National Geographic Reflector Telescope with Panhandle Mount.

What are the two most important characteristics of a telescope?

The two important properties of a telescope are light-gathering power (light bucket) and resolving power. Light bucket improves out ability to see distant or faint objects and is proportional to the square of the radius of the primary mirror.

What are two purposes of a telescope?

The most important functions of a telescope are (1) to collect the faint light from an astronomical source and (2) to focus all the light into a point or an image. Most objects of interest to astronomers are extremely faint: the more light we can collect, the better we can study such objects.

What are the disadvantages of telescopes?

Disadvantages: Expensive at larger apertures. Unwieldy with large refractors. Chromatic aberration and blurring if it not corrected.
