When it comes to telescopes, there are a variety of shapes and sizes. There are actually a few main types based on how they work and what they are used to view. Since the first one was developed in the 17th century, people have been looking towards the stars. They're wondering what's out there, and fascinated by the possibilities. Today's telescopes are light years beyond the ones developed all those centuries ago. They're able to see deep into space towards galaxies and distant stars. Telescopes come in a few types based on what they are meant to view like space telescopes or solar telescopes. The Refracting Telescope An optical telescope is one that an astronomer uses to view planets and galaxies with their eye pressed to an eyepiece. …show more content…
They usually have a large aperture for allowing more light to enter through the primary lens. The lenses are large and the body or tube is quite long. This will have an impact on the price of the telescope since high quality lenses are vital for the images' clarity. A heavy telescope is harder to transport, so that should be kept in mind when finding a telescope for amateur astronomers as a gift. Reflecting Telescope This type of telescope is known as a catoptrics version of a telescope. The tube and lens system is similar to that of a refracting telescope. There are many things similar, but others are vastly different for a reflecting telescope. The tube allows light to enter through one end. On that end is a primary mirror, and on the other end is a secondary mirror. The primary mirror reflects the light to the secondary mirror and towards the eyepiece. The eyepiece is normally mounted on the side of the tube, which is how you can see the difference immediately in a telescope. Reflecting telescopes are popular because they're smaller and compact compared to refracting telescopes. This allows astronomers to break them down and carry them to other locations quite easily. It's important to be careful with the mirrors, though. They can be knocked out of
...ossessed with three dimensional attributes. The optical effect may be explained by the fact that the human eyes see an object from two viewpoints separated laterally by about six centimeters. The two views show slightly different spatial relationships between near and near distant objects and the visual process fuses these stereoscopic views to a single three dimensional impression. The same parallax view of an object may be experienced upon reflection of an object seen from a concave mirror." (http://www.freepatentsonline.com/4229761.html).
The oldest form of oscilloscope, still used in some labs today, is known as the cathode-ray oscilloscope. It produces an image by the focused electron beam to travel in patterns across the face of cathode ray tube (CRT). More modern oscilloscopes electronically replicate the action of the CRT using a liquid crystal display (liquid crystal display) like the one that can be found on notebook computers screen.
The only other painting that Velázquez is known to use a mirror in is Venus, where it is used an aid (Harris 174). However, the usage of the mirror is used differently, it is only used to create depth for Venus (Harris 174). Las Meninas was not the first painting to “draw the eye inwards and bring the spectator in”(Harris 174). Jan van Eyck’s Marriage Portrait of the Arnolfni, where the mirror reflects the married couple in front, and another person whom is assumed to be the artist, displays those characteristics (Harris 174). People believe that Van Eyck’s painting gave Velázquez this complex idea.

Binoculars - A tool you look into used to make things look closer than they are so you can see it more clearly.
What is astronomy? Astronomy consist of a lot of things that make up our solar system such as: the nine planets, asteroids, meteorites, the moon and the sun. Astronomy is also a fascinating hobby that can be followed by anyone. You do not need to be, as some people seem to imagine, ‘mathematically-minded’ , in order to start, or even to become a very experienced observer. Yet astronomy is one of the few hobbies where not only can you gain great enjoyment, but if you feel want to can very easily make observations of great scientific value.
Mirrors are first introduced in part one of the novel where Clarisse is describes as a mirror by Montag. Also presented by Granger towards the end of the novel, the mirror is a symbol of the lacking self-reflection but also it cure. Mirrors reflect a perfect image of a person back at them – an image that is neither tarnished nor beautified. Mirror here are a symbol of seeing within one’s soul in pursuit of rebirth, and are a tool to be used in the search what has gone terribly wrong in such an empty society. In a society that lives without living, thinking or feeling like Montag’s looking into a mirror ma spark a thought, and a thought may spark that internal rebellion. Furthermore, metaphorical mirrors are of equal significance when understanding this symbol. Clarisse is Montag’s inner mirror; she reflects the personality and life of Montag back at him, allowing him to learn and question what he sees. Montag is also Faber’s mirror – he reflects Faber’s recent emptiness and his cowardice at not attempting release society from its suffering. Mirrors are a great symbol of self-actualization that leads to rebirth in the novel Fahrenheit
In 1610 he was one of the first people to use the telescope to observe
Light rays gather through the opening of the telescope called the aperture and pass through the objective lens and refract onto a single point called the focal point. From there, the light rays continue in the same direction until it hits the eyepiece lens, which also refracts the light back into parallel rays. During the process, the image that enters our eyes is actually reverse of the original image and magnified because of the size in which we perceive the image.
The telescope was invented based off of a “spyglass” that was created by a Flemish lens grinder. Galileo was a man of many trades; philosophy, astronomy, and mathematics were among his favorites. Before he started studying the skies, Galileo taught math at Pisa and then Padua. After creating his telescope he became known as a hero to many people across Italy and most of Europe.
The Hubble Telescope is the world’s first space-based optical telescope. The Hubble telescope received its name from American astronomer Dr. Edwin P. Hubble. Dr. Hubble confirmed an ever expanding universe which provided the basic foundation of the Big Bang theory. The first concept of the Hubble telescope came from Lyman Spitzer in 1946, who at that time was a professor and researcher at Yale University. In 1946, Professor Spitzer believed that Earth’s atmosphere blurs and distorts light, and a space orbited telescope would be able to overcome this problem.
Cyber Attack on Island of Telescopes Not only is Hawaii a sort of paradise, it’s also what seems to be a native and comfortable habitat for larger telescopes. Since Hawaii is much further away from any light and has minimal air pollution, it’s a perfect spot to look up at the night sky. Right on the island of Mauna Kea lives thirteen different telescopes, including the coming TMT or Thirty Meter Telescope. It will become an island of telescopes if it hasn’t already.
The refracting telescope is one of many different types of telescope. Refracting telescopes work by refracting the light through an initial convex lens, (known as the objective lens), then through another convex lens (known as the eyepiece lens). These two lenses focus the light into the eyepiece so we can see the image clearly.
One thing us humans have never been able to fully understand is astronomy. Always an unexplained mystery, astronomy also serves as a way to keep time and predict the future. The word “astronomy” is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, are amazed by the night sky on a clear, moonless night. Astronomy dates back to ancient times when peoples such as the Babylonians, Egyptians, and Chinese kept written records of astronomical events and occurrences.
Isaac Newton created the first 'practical' reflector in 1668, which included a small flat diagonal mirror to reflect the light to an eyepiece mounted on the side of the telescope. With time, telescopes became bigger and more sophisticated, and astronomers discovered more stars and galaxies. They were also able to calculate the distance between stars. Most of the large optical telescopes used for research today are reflectors.
