Since ancient times, humanity has looked at the stars with the desire to reach those bright spots.
Of course, reaching the stars is still a dream, but thanks to telescopes, we are a little closer to the cosmos. In this article, you will find everything you want to know about the world of telescopes.
Do you really know who invented the telescope?
The desire to know our place in the universe led to the invention of the first telescopes, made up of two crystals in a tube. Knowing that the planet earth was not the center of the universe, a religious persecution against any scientific advance was unleashed. For this reason, historically it is difficult to know exactly the origin of the telescope.
It was the Catalan, Joan Roget, who invented the telescope as a toy for his optics in Barcelona in 1570. Later, the German, Hans Lippershey, patented an instrument known as a “mirador”, translated in Spanish, with a similar structure to that of a rudimentary astronomical telescope.
In general, there was a false belief that Galileo Galilei had been the inventor of the telescope or any similar instrument, but he was really the one who perfected it. His original design is a refracting telescope with a convex glass in front and a concave glass in the back. P>
With this instrument, the first step towards the observation of the planets and stars was definitively taken, which would change the entire vision of the universe that had been held until then.
What are telescopes and how many types of telescope are there?
Telescopes are optical instruments that allow celestial bodies to be observed by capturing their electromagnetic radiation in the form of light.
With the advancement of science, we have developed ground-based telescopes and space telescopes with which we can see to the ends of the galaxy. But a question arises, how does a telescope work? How a tube with crystals can give you a vision of your existence? Telescopes use the magic of optics and light.
Telescopes use lenses to collect light in the form of parallel rays from objects, telescopes that use mirrors enhance reflection by reflecting the light and directing it to a secondary mirror and then to the eyepiece.
Types of astronomical telescopes
All telescopes used to observe space are divided into three types, depending on their design.
Also known as a lens telescope that works by capturing light from celestial bodies through lenses that capture the light and concentrate it into a focus.
This type of telescope does not need large openings to capture the light emitted by the observed bodies. With them you can clearly see distant stars, large planets and very bright double stars.
Unlike the previous one, the reflector or mirror telescope uses a concave mirror at the lower end of the tube that bounces the light towards the eyepiece. This mirror is placed at a 45° tilt.
This type of telescope allows the observation of deep space, the famous Hubble Space Telescope uses refraction to provide excellent images of nebulae, galaxies, supernovae, even black holes.
Combined or catadioptric telescopes
They are telescopes that combine mirrors and lenses to try to correct the aberrations that refracting and reflecting telescopes may present. Its design is very complex since it combines a concave mirror with a corrective lens that supports a secondary mirror.
When light enters the telescope objective, it is directed towards the center of the mirrors giving you a very large field of view.Despite their design, this type of telescope generally does not allow some elements to be observed with great precision.
Which is the best telescope?
Keep in mind that telescopes allow you to observe different things. Refractor telescopes allow you to observe bright objects clearly, reflector telescopes deepen the observation in outer space, while catadioptric telescopes are perfect for beginners and explorers of the night sky.
The best telescopes for amateurs
Many people think that these instruments are extremely expensive or even try to make a telescope using homemade materials. But there are very viable options to buy a telescope with which you can observe infinity.
The Celestron telescopes are recognized worldwide for their versatility, they have manual and automatic models. They offer high-contrast images without chromatic aberrations, so they are perfect for distinguishing new objects. If you have any questions about how to focus your telescope the Celestron team has a customer service line that is at your disposal.
For their part, the Bresser telescopes are designed for amateurs and experts in the field of astronomy. They have classic designs and models with perfect refractors to capture images of bright objects.
If you want to get started in astronomy, you can't stop using the Bresser telescopes, since they have a line of mid-range telescopes designed for children and amateurs.
Another interesting model is the Starblizt refracting telescope with a design similar to that developed by Galileo Galilei, which allows you to observe planets and nearby stars with great clarity. It also has a mid-range of very attractive children's telescopes,
What is the future of telescopes?
Space exploration has made huge strides today. Every day astronomers look further and further into the vast and infinite universe. There are telescopes on land
Following the Hubbel Telescope and the Spitzer Space Observatory, space agencies around the world have combined efforts to take space observation to the next level. The most important project in the world of astronomy is the launch of the James Webb Space Telescope. It is a joint effort between 17 countries that will be launched into orbit by 2021.
This project is not just a traditional space telescope, it is a space observatory that aims to give astronomy a new meaning. With this six-ton instrument, it is intended to take never-before-seen images of the ends of the universe. The study of the formation of distant stars and planets, exoplanets that may harbor life, supernovae, and other impressive physical phenomena.
