The telescope is one of the most used artifacts as far as vision is concerned, astrologers use them to be able to locate the constellations , in addition to this, it has several uses apart from it , not only scientists use it, but there are versions more specific which are for homes and individuals.


What is a telescope?

The telescope is recognized as an instrument or visual artifact that is responsible for collecting enough light so that it is concentrated at a specific point in the field of vision and it is possible to observe diverse objects at a distance with more meticulous and determined detail.


Definition of telescope

This has its etymological origin in two Greek terminologies, which are τηλε which is pronounced tele and is translated into Spanish as far or apart , and from the term σκοπ , which is pronounced skop and is translated as see or observe , that is, that this artifact works when observing things in the distance, coupled with it, thanks to an input of light that is focused at a certain point which allows this function; It is one of the fundamental tools in astronomy , which makes it an extremely important instrument.


On the other hand, it is worth noting that each of the versions of this artifact or its improvement has been of great importance for what is the development and evolution of humanity , with respect to what is the understanding of the universes and the oddities that it hides ; Thanks to this artifact, it was possible to begin to discover what is the true and pure nature of stars, constellations and comets , which appear from time to time, coupled with this, a low idea was obtained that later triggered many theories of our whereabouts in the universe in which we inhabit.


The telescope has a controversial origin, so to speak, since many famous scholars of the 1500s were determined to patent the idea, even so it was plagiarized, however, its invention is attributed to Hans Lippershey , who was a German who was dedicated to the art of making lenses, this invention tried to be copied not once, not twice, but three times, Juan Roget was one of those who wanted to seize the invention of this in 1590, however, it was not until on October 17 of the same year that another candidate to copy the artifact appeared patenting the object named Zacharias JanssenHowever, Lippershey had already patented the product two days before the event.


After the controversy when this artifact originated, Galileo Galilei was curious about it and decided to create one, after that in 1609 he publicly showed his design of an astronomical telescope , it was not until 1610 that it was observed for the first time through it , This caused a great development in the discoveries about the universe , one of the most prominent and most renowned is the admiration that was witnessed by 4 of the moons of Jupiter rotating in orbit, on January 7, 1610.

What is a telescope for?

This device works accurately and precisely when evaluating and observing figures, objects and shapes from a distance, thanks to its focus of light and the capacity of the lens it has ; It is used most of all to see the stars, constellations and comets, in addition to this, to recognize the movements of the earth with respect to the rest of the universe and to know more deeply what are the phenomena that are triggered in that area.


Some of the characteristics that immediately distinguish telescopes are the following:

  • It has a focal length , which is the distance between what is the mirror and the main lens.
  • In it there is an eyepiece , which is what allows vision and gives the opportunity to magnify the experience.
  • It has a filter , which commonly dims the image that can be seen through the artifact.
  • All telescopes have what is called a limiting magnitude , that is, they generally have parameters of how much can or cannot be observed in a telescope.
  • In the same way, they have the ability to enlarge the displayed image.
  • Mostly a tripod is used as a base when using telescopes.

There are various types of telescope, however, the most mentioned are the following:

  • The refracting telescope .
  • The reflecting telescope .
  • The catadioptric telescope .
  • The cassegrain telescope .


This artifact consists of many parts that contribute to its complex shape, it is composed as follows:

  • The searcher.
  • The eyepiece.
  • The decline movement.
  • The primary mirror.
  • Frame.
  • It weighs it.
  • The axis of DEC.
  • The axis of AR.
  • The tripod.

How does it work

This device collects and captures as much light or luminosity as possible , focusing it on a single specific point in the field of vision so that in this way the user can observe objects in the distance that are opaque or with little light , in this way and with the different functions that this has, you can obtain clear and defined images of the objective in question.

Featured telescopes

  • Hubble Space Telescope.
  • Very Large Telescope.
  • Canary Islands large telescope.
  • Hale telescope.
  • Mount Wilson Telescope.
  • SOHO space telescope.


The importance of the telescope is found in the great findings that have been made thanks to the artifact, strongly impacting what is the evolution of the human being as a person and as a connoisseur of his environment and his universe.
