Reflector Telescope

Astronomy seems at the outset to be something of only a viable hobby if you have a telescope. This can stop a lot of people from taking part in this hobby as the thought of shelling out a fortune on a telescope seems frivolous. The truth is that you can build your own Newtonian reflecting telescope mirror.
Building a telescope seems like a huge task but it is in fact very easy to do and you can make one in a day. While making your own reflecting telescope mirror may not give you the best reflecting telescope it is a way to start your foray into astronomy at home.
What You Need
Making your own reflecting telescope mirror can be very simple and you will not need a PVC pipe to hold your parts together. You will also not need a tripod to support your telescope. While a tube and tripod seem essential to build a telescope you can make a very simple one without all these things. All you need are two lenses.
The first things you will need when making your own reflecting telescope mirror are the lenses. You will need an objective lens. This can be a lens that is used in a magnifying glass. A simple guide to making your simple telescope more powerful is to look for a weak magnifying glass.
The strength of the lens is inversely connected to the strength of your telescope. The weaker the lens the stronger the telescope. Look for a lens that is thin in the center of the lens, the objective lens should always be a Convex lens. Look for a lens that is large as well as weak to make your telescope more powerful.
Next you will need to find your eyepiece. If you are building a Newtonian reflecting telescope mirror you will need to use a convex eyepiece for your second lens. However using a convex eyepiece will mean that everything you see through the eyepiece will be upside down.
If you would like to turn everything the right way around then you can use a concave lens for your eyepiece. When you use a concave eyepiece for the eyepiece it is no longer a Newtonian telescope but a Galilean telescope.
The best kind of eyepiece to use would be a small powerful eyepiece such as a magnifying loupe. Now all you have to do is hold the eyepiece right to your eye and close the other eye. Hold the objective lens out in front of your eyepiece and you now have a simple telescope.

You might have noticed that all major research telescopes are reflecting telescopes. So this would seem to indicate that the best kind of telescope would be the best reflecting telescope you could find. You would be right about this. The best reflecting telescope will give you the best view of the stars and planets in the universe. The reason for this is very simple. A reflecting telescope is the telescope that will collect the most amount of light and thus will give you a clearer picture of the sky.
Simple Concept
The idea behind the best reflecting telescope is that you can use the lenses to focus the light that can be collected by the mirrors to give you a clear picture. One of the problems that people face when using a refracting telescope is that chromatic aberration occurs.
This means you will see rings of color around certain images, this can be distracting and to find the best reflecting telescope you need to eliminate chromatic aberration. One way to do this is by using reflecting telescopes as mirrors reflect all light and chromatic aberration will not occur.
Another reason that the best reflecting telescope is used in research facilities is that it can be supported easily. One of the reasons you can support a telescope made from telescope eyepiece mirrors is that you can support it more than from around the sides. Even with a very heavy telescope you don’t have to worry about shaking and movement distorting the images you are seeing.
These two advantages mean that the best reflecting telescopes are the telescope of choice for research facilities the world over. The lenses can be much bigger but at the same time they can be easily supported without interfering with the light collection that is vital for clear images.
Secondly it is easier to use this kind of telescope because chromatic aberrations do not occur giving a clearer and more true picture of what is going millions of miles away. Even though the best reflecting telescopes are used in high tech facilities you can use similar technology for your own backyard star gazing.
There are many telescopes that are built for home use using this technology. You can ever build your own telescope with this kind of design at home. You can decide to make this telescope as simple or as complicated as you like. Find a good manual and some parts and you will soon have your very own reflecting telescope to use at home.

The reflecting telescope is widely used today in astronomy and most major astronomical telescopes are reflecting telescopes. The first reflecting telescopes were created in the 17th century but it failed to catch on and become an important part of astronomy due to design flaws that prevented it from being widely used.
Over time the first reflecting telescope design was revisited and refined. Today reflecting telescopes have come a long way, such as the Meade reflecting telescope, even computer technology has been integrated into the design to further improve the technology and the images that can be provided by telescopes.
Flawed Beginnings
The first ever reflecting telescope was designed by a Jesuit priest, Nicolaus Zucchius in Italy. This first reflecting telescope was introduced in 1616, and allowed him to view two bands on Jupiter in 1630 and to see spots on Mars in 1640.
However this design had a major flaw in that Zucchius was unable to shape the mirror to a proper concave shape. Another problem encountered with the first reflecting telescope was the fact that you could not view the image without first blocking the mirror. Due to these flaws this particular design was never widely used.
A more practical design of the reflecting telescope was conceived in 1663 by James Gregory. This design involved the use of two concave mirrors. A model of this design was not built until ten years later by Robert Hooke. The next first practical reflecting telescope was built by Sir Isaac Newton.
Chief among the design innovations that were invented by Sir Isaac Newton was a diagonal mirror near the telescope’s primary mirror. This allowed the primary mirror’s focus to be reflected at a 90 degree angle, which meant that a viewer could view the image without blocking out all the light coming through the telescope.
This design innovation also cut down on chromatic aberration, a problem that plagued most refracting telescopes of the day. Today the reflecting telescope has come a long way. There are now telescopes that are positioned above the Earth’s atmosphere.
The images and sights that can now be viewed through reflecting telescopes far exceed what the first reflecting telescope could ever show you. Despite all the advances in technology the design that is most popular among those keen to build their own telescopes is the one first designed by Sir Isaac Newton. Proving that some designs are classics and will never completely fade away.

If you are a beginner to intermediate astronomer or soon to be ardent star gazer then using a Meade reflecting telescope is for you. When you are starting out in astronomy you want a telescope that is easy to use and will give you clear images. The clarity of the images is essential to allow you to correctly identify the planets and stars that you are looking out for. Using a Meade reflecting telescope is a great way to start your astronomy adventures.
Latest Technology
When you decide to buy a Meade reflecting telescope you are going to be using the latest technology. Whenever you decide to buy a telescope you want to make sure that you are using the latest technology and you can be sure with a Meade reflecting telescope that you are using the best technology and at the same time you will be using a telescope that is easy to use.
Meade technology has been careful to make sure that new users will not have trouble using the telescope. Most telescopes from this company use electromechanical and design and microprocessor technology, the best of everything makes this reflecting telescope mirror one to watch.
One of the exciting parts of the new line of Meade reflecting telescope is that you can immediately find anything you want to find with the Autostar Computer controller that can help you to find anything in the sky when you choose a specific object, such as a particular star, in the menu of the software.
Good Starting Point
The great thing about using a Meade reflecting telescope is that you can use this as a starting point for your astronomy journey. Once you start to gain confidence in your ability to find stars, planets, and other objects on your own then you will be able to rely less on technology.
For young children this is also a very handy tool as they will be able to familiarize themselves with the starts and constellations with the help of the software and will later be able to spot the constellations without the help of a telescope of the software that comes with it.
Teaching children about the solar system and the universe is easier when they can visualize the planets and the Earth’s position in the grand scheme of things is much easier when they can actually see out into space. Children will be fascinated by the stars and the use of the telescope.

While to the casual observer telescopes might all seem to be alike, those in the know realize that there are big differences between reflecting and refracting telescopes. Differences that were immediately apparent when the reflecting telescope was first conceived. It doesn’t matter if it’s a homemade reflecting telescope or the largest reflecting telescope.

The differences will be apparent in the degree of clarity and image quality in the two very different telescopes. While each type of telescope has its advantages there is no one telescope that is perfect, each type will allow you to see different things.

Optical Construction

The immediate difference between the two types of telescopes is the optical construction of reflecting and refracting telescopes. The names of the telescopes themselves give you a clue as to how these telescopes are constructed.

A reflecting telescope is made up of a series of mirrors that reflects light rays. Reflecting telescopes can be used to view brighter planets and stars in astronomy. A refracting telescope on he other hand is made up of lenses that refract light rays.

The best way to see a wide variety of astronomical sights is to have both reflecting and refracting telescopes. Having both reflecting and refracting telescopes on hand will allow you to see more stars and planets.

Choosing A Refractor

You may decide after considering reflecting and refracting telescopes that the best option for you is a refracting telescope. Choosing this type of telescope will allow you to do daytime viewing. Fitting your refracting telescope with an image rectifier will give you better daytime viewing.

Another plus of using a refracting telescope is that you will be able to see the stars and planets in greater details. A refracting telescope also allows you to see things in greater contrast and you will see higher emissions of light through this kind of telescope. This is a great telescope to start with as will allow you to easily identify familiar stars a it is a brighter telescope than a reflecting telescope.

If on the other hand you decide that between reflecting and refracting telescopes you would prefer a reflecting telescope then this also has other advantages. A reflecting telescope will allow you to see galaxies and nebulae and other lower light objects. If you would like to start astronomical photography then choosing a reflecting telescope is probably the best option. It really depends on what you would like to use your telescope for.

Reflecting telescopes are an important tool in the field of astronomy and reflecting telescopes allow for scientists to study planets and stars while still keeping their feet firmly on the ground. Obviously the larger the telescope the more powerful it is and the more it can tell us about space and many of the things in the universe that are still being discovered. So where is the largest reflecting telescope? The largest reflecting telescope is at this moment in Hawaii.
Importance Of The Largest Telescope
The largest reflecting telescope at this moment in time is in the Mauna Kea observatory. It measures an impressive 387 inches or 982 cm. The largest reflecting telescope is called the Keck telescope. There are a number of large reflecting telescopes around the world but at present this is the largest reflecting telescope.
The largest reflecting telescope is important because of its design. There are certain aspects of its design that are seen as innovative. Chief among its innovations is the fact that its primary mirror is actually made up of 36 seperate hexagons.
All of which can be positioned and kept aligned by electronic technology. The individual segments mean that the mirror can be thinner and lighter than if it were made of one large piece of mirror. This has the advantage of making the largest reflecting telescope lighter than the first reflecting telescope. Transporting and cleaning the telescope is also much easier with this design innovation.
The Best Telescope?
While the largest reflecting telescope certainly provides powerful images of space it is not the best telescope. The Hubble Space telescope has the advantage of being positioned above the Earth’s atmosphere. Even with a distorted primary mirror the Hubble telescope was able to give superior images of space.
After being repaired the Hubble Space telescope has continued to provide superior images to any other telescope in use at present. It will soon be outdone by new technology that uses computers to change the primary mirror to provide better images. The ability of the computer to alter its primary mirror means that it can get around the turbulence of the Earth’s atmosphere.
The largest reflecting telescope will also face competition with the completion of the Very Large Telescope that is under construction in Chile. This telescope uses the computer technology mentioned earlier and once it is completed it will be the world’s largest optical telescope. Both its size and the technology it employs will make it one of the best telescopes in use.

Reflecting telescopes have been used for a long time now. They were first invented in the 17th century and are sometimes called a reflector which has led to confusion with the reflecting and refracting telescope. The refracting telescope precedes the reflecting telescope but it is rarely used and most telescopes used today are of the reflecting type.

This is because refracting telescopes suffer from chromatic aberrations, a result of the different refractive indexes on the lenses in such telescopes. What this means is that around each image, color fringes appear. While this can be reduced it is easier to use a reflecting telescope.

Design Considerations

The first reflecting telescope to solve the problem of chromatic aberrations was a telescope invented by Sir Isaac Newton. The Newtonian design for reflecting telescopes is still in use today and is one of the simplest designs of modern telescopes available today. It is also one of the least expensive telescopes. Anyone deciding to make their own telescope would be able to put together a reflecting telescope of this kind.

The Cassegrain or Classic Cassegrain telescope is also very popular and this is in part because of its compact design. This is achieved by folding the optics in the telescope. While the design does lose some light gathering power it has an advantage with a closed tube that stays clean all the time.

Most professional telescopes follow the Ritchey-Chretien design. It is an offshoot of the Cassegrain design and has two hyperbolic mirrors. This design characteristic differs from the Cassegrain, which employs one parabolic primary mirror instead. This kind of telescopic lens is ideal in photography.

Another reflecting telescope that is used is the Yolo. One of the problems associated with this telescope is that of astigmatism. This can lead to double vision and certain blind spots. This can be corrected however and one of the advantages of this telescope is the fact that it eliminates the problem of coma, a problem prevalent in many telescope designs.

Depending on your specific needs there are different types of reflecting telescopes that would best fit your specifications. For amateur telescope building and astronomy starting with a Newtonian telescope is a good place to start.

It is also the least expensive kind and a good starting point when you are just beginning to explore the world of telescopes. Once you have ignited your passion there are many other designs that you can try out for star gazing and wide field observation.
