The Best Telescopes to Buy For Kids

!±8± The Best Telescopes to Buy For Kids

Discovering astronomy with your first look through your first telescope at one of our major planets such as Saturn or Jupiter and even our very familiar moon is the beginning of a lifetime of pleasure, in discovering the wonders of the night sky. However if the first telescope you get is a standard tripod mounted refracting telescope (one using lenses not mirrors) as found in most department stores, the experience is usually one of frustration and disappointment instead.

It is very tempting I know, when you see the telescope for maybe to 0 with claims of "Magnifies 600 times" or "See galaxies and nebulas" to think that this will delight your children. The reality is one of these telescopes will have a wobbly tripod that will not allow you to see anything at 60 times, much less 600. The aperture (that's the diameter) of the lens will typically be 70 to 90 mm and this will never gather enough light to see faint and distant galaxies, most of which are millions of light years away.

So what can you do? Well, in my experience of almost 10 years of showing 1000's of children and my own 3 kids around the night sky, the best way to start is in fact with a Star Disc, a red light and a pair of low powered binoculars. The reason is that for starters you will need to find something worthwhile to look at. A Star Disc will show you a few bright deep sky objects that are easily seem with binoculars on any given night. The red light will allow you to see the Star Disc without ruining you night vision. Your night vision takes at least 20 minutes away from white light to adapt to the darkness. A low powered pair of binoculars (EG: 8x50 - 8 times magnification and a 50mm lens) will show you many faint galaxies, nebulas and star clusters. A picnic blanket is a good idea to lay on as well. What a great way to get the family together!

Perhaps you have already done this and are ready to make the next step, and really want to get that telescope. What should you do? My experience and that of my astronomy peers from around Australia and across the world have shown me that the telescope that is (a) Quick to set up and pack up (b) Easy to use and (c) has preferably at least 200mm (8") of aperture will get the most use and provide many years of observing pleasure. Not just for the kids but the whole family and many friends.

What does one of these telescopes look like? Well, it is not a refractor and it is not on a tripod. It is a Dobsonian mounted reflector. A reflector is much like the telescopes used in professional observatories (only much smaller!) Put in simple terms the telescope is mounted on a horizontal (azimuth) turntable close to ground level allowing you to move the telescope to all points of the compass and a vertical pivot point allowing you to move the telescope from the horizon to directly overhead (the zenith) through 90 degrees. The eyepiece (this does the magnifying) is in the side of the telescope tube at about 1.3 meters above the ground, an ideal height for kids. A 200mm (8") Dobsonian is lightweight enough that a child of perhaps 10 years old can easily move and set it up in the park or backyard. Confused about what it looks like? Just imagine a cannon that spins around and can point straight up.

How much is one of these going to cost you? You may be thinking thousands of dollars. In fact, a 200mm Dobsonian can cost as little as 0 in Australia and a similar amount in the USA. So start into astronomy the fun and easy way and your Christmas present will live on for many years to come.

Choosing the Best Telescope For Kids - Beginner Telescope Buyers Tips

!±8± Choosing the Best Telescope For Kids - Beginner Telescope Buyers Tips

One of the best gifts that you can give a child is their first telescope. Nothing beats the excitement of peering out in to space for the first time. The first close glimpse of the moon and all of it's craters and the sight of Saturn's rings all amaze children and adults alike.

Choosing a telescope for a child is tricky. You want to ensure that you select one of quality. Toy stores carry a selection of telescopes but the sad fact is that most of them are junk that barely work. A little research before you buy can make all of the difference. There are affordable high quality scopes available that are designed to be easy to use for first time star gazers. On average, you can expect to find a quality scope for - 0 on sale or a bit more at retail. Researching and price comparing on the web can score you even better deals.

The most important part of a telescope is the lens. Most starter scopes have what is known as a "refracting lens". These lenses magnify objects by using a convex bent glass. They are adjustable for focus and field of vision. This allows the user to point the scope at an object in space and focus the scope on the object.

If you are shopping for a telescope for beginners, you may also wish to consider giving a guide to the stars and planets. There are many good books for children and young adults that will help them understand more about what they are seeing through the scope.

The first thing that most people want to view with a telescope is the moon. After examining Earth's own satellite and all of it's craters, the next stop is likely the ringed Saturn or even the big dipper and Little Dipper. The Gemini Twins and Orion also make for exciting viewing with a new backyard telescope.

There is no better way to encourage a love of learning than the gift of a hands on experience. When you shop for a beginners telescope you are doing more than giving a simple gift. You are unlocking curiosity and an interest in science that will stay with a child for years to come. Who knows, you could even inspire the next generation of astronauts!

Who Really Invented the Telescope?

!±8± Who Really Invented the Telescope?

For most of us, we thought that Galileo Galilei was the inventor of the telescope, because it is what our science teacher told us, and that is what we read in our science books. But the truth is that they are wrong, because even if Galileo is one of the greatest astronomers of this planet has ever produced, was not he who invented the telescope, so they invented the telescope is a question that has plagued our minds .

The answer to the question of who invented the telescopeHans is Lipperhey. Yes, he was the one who invented the telescope and its invention has contributed significantly to the world of astronomy and science as a whole. The telescope has changed the landscape of many things in our world. The telescope is not alone in discovering the world beyond our planet, such as stars, planets and other astronomical objects, but also used in our daily lives. For example, a telescope with the support of navigation and transport, as a vessel used, and is also used inmilitary as an instrument of protection and defense of territories.

Now back to the question of who invented the telescope, this guy named Han Lipperhey the cause of a great change in our world, and was born in Germany and built his home in Holland. Married in 1954 and a citizen of The Netherlands 1602, was a merchant of professions. At the time when the Italians came up with techniques of glass, which was introduced in the Netherlands, such a development has brought newIdeas and progress, and then people began to try different ways to create lenses. It was in 1608 that the telescopes were invented.

The truth was that there was only one person who invented the telescope, since the invention of three people, and Hans Janssen and Jacob Metius Lippershey Zacharis can be given. After the invention of the telescope were then produced in quantities and were distributed throughout Europe and then America and Asia. The first telescopes can only increasesize of an object thrice its original size. But the present telescopes can view object that are light years away and can see even the tiny object and magnify them.

When did Galilei enter into the picture? He actually did not invent the telescope but added some things because he put a convex and concave lens in a tube so what he did was an improved version of the original one. So Galilei was not really the one who invented the telescope.
Now here is the twist to the story because there was a rumor that circulated that it was neither Galilei nor Hans who invented. It was the children of Hans who found out about the telescope while they were playing. But that side of the story on who invented the telescope was not yet proven. So at this point, we have to settle with the more believable version and that is, it was Hans and two others who invented the telescope.

Shining light on Star Refractor

!±8± Shining light on Star Refractor

Although Galileo has been historically credited with the invention of the refracting telescope in early 1600, should claim to three ophthalmologists, whose work has helped to be taken for his telescope in the development of the theory of refraction. Refractors are very simple and have only two main components - the objective is called convex lens and a concave lens, where the eyepiece.

The convex lens is at the end of the telescope and is used to bend or breakLight enters the telescope and turn it into a single beam of light. Then the image has come to be seen in the opposite direction on the concave lens, the image is reversed. Refractive telescopes allows the viewer to see a very bright and clear image.

Galileo invented the refracting telescope is currently used by many people, but the drawback is the small field of view it offers. A well known is the refracting telescope in California, at the Chabot Space and Science Centre. The centeractually has two refractors - an eight-inch refractor and a 21-inch refractor. Telescopes are very simple, and this can lead to spherical aberrations. One way, these aberrations will be treated with a pair of lenses (a convex lens and an apartment) in order to create an achromatic lens.

Refractors and color

One of the most common problems with a refractor is the separation of light that occurs when light is bent. If thishappens, is called chromatic aberration, and can be solved with the use of an achromat.

One of the main problems with the refracting lens becomes large enough, without imperfections, which are collected as the light through the lens. There are 41-inch lenses, but they are useless. Refractive telescopes ends are not usually used by professional astronomers around the issue of light to focus on a place at the same time.

Break-Telescopes are very popular among astronomers and novice observers are used throughout the world. It 'a good choice for beginners telescope surrounded by the lens, the image look less wobbly and doing less exercise than reflecting telescopes, which makes the image to the eye of the beholder to send in a mirror. The process of reflected light from the mirror first and then the second eye, an unstable.
