New Telescopes for Beginners

!9#: New Telescopes for Beginners

There are two basic types of telescopes: one in the reflector and the other is the refracting telescope. It is important to know the difference so the you can choose what is correct for your circumstances.

The first telescopes were the refractor type. A man named Lippershey was tinkering with eyeglass lenses and noticed that when he place one lens in front of the another the object resting just beyond the lenses were magnified slightly.

He soon built the first spyglass, the first optical telescope which focused light into the human eye. It also used two lenses. The first lens (the objective lens) collects and refracts (bends) incoming light, focusing it into a tiny image.

The secondary lens, placed directly in front of the first, magnifies the image, making it look larger to the eye.

This new invention was used as a novelty at parties and later by army officers to observe enemy troop movement up close. No one thought about using it to study the skies.

Galileo is best known for taking this invention, improving on it with more magnification, and turning it upwards to observe astronomy. He was the first to see other planets.

Telescopes were not only getting larger and more powerful the quality of the lenses were improving rapidly making images sharper.

A Scottish mathematician named James Gregory in the 1660s tried building a telescope that used mirror instead of a lens to gather light.

Isaac Newton picked up on the idea, came up with a simpler and better reflecting telescope, or a reflector. Light enters the telescope's tube from an opening in the front. The light travels to a mirror located in the back and bounces off.

Because the mirror curves inward slightly the reflected light comes together and forms a small image in the center of the scope.

To get the best viewing for your money your best choice would probably be a good pair of binoculars (two telescopes for the price of one). After that reflector telescopes are great for beginners. When you have more experience move up to a refractor telescope.

Happy viewing, mary

Best Beginner Telescopes

!9# Best Beginner Telescopes

[if ]
[endif]

I'm sometimes asked to recommend the best beginner telescopes and my first comment is often "the one you are most likely to use"! It's not that I'm intending to be blunt or to cause further confusion but seriously one of the over-riding factors is going to be whether you are going to be inclined to haul a big heavy telescope around or whether you are really only going to use something very light and portable.

You see all things being equal the diameter of the lens or mirror (depending on what type of telescope you get) tends to govern what you can achieve with the telescope. Bigger is generally better, in that the bigger scopes capture more light and allow greater magnification for seeing those deep-sky objects.

Magnification however is a two edged sword, too much and you will just end up with a fuzzy image so there is a trade-off to be balanced. In very broad terms, take the diameter of your lens or mirror in millimetres and multiply it by 2 to know the upper limit of magnification for the scope.

Refractors tend to produce slightly sharper images than reflectors but good big refractors can be difficult to use properly and very expensive. Reflectors on the other hand are easier to manufacture so are cheaper and often more easily handled by beginners. That said a simple small refractor is easy to grab for a quick casual session on the roof or deck and can be a handy little instrument in the city or suburbs where light pollution can overwhelm larger reflectors anyway.

Buying for kids and living away from the suburbs? The big Dobsonian telescopes are really excellent, so simple to use, giving great views but really best away from the city, (they are pretty cumbersome to transport too).

Catadioptric telescopes are sort of a half refractor and half reflector and are capable of capturing great images, indeed they are often used by astro-photographers but that is a subject a little more advanced than the usual beginner level telescope buyer needs to get too wrapped up in.

Another over-riding factor is the obvious one of budget. There are some really awful scopes out there aimed at beginners but in truth likely to give the poor buyer such a bad experience that it turns them off amateur astronomy for ever after! Avoid those eBay and department store 'bargains' if you want a good experience or want to encourage a young astronomer.

Amazon however has some truly excellent telescopes on offer from a variety of good brands like Celestron, Orion, Sky-Watcher, Meade and others at really great prices. Be aware though that depending where you are in the world you might not be able to purchase from there because of international warranty arrangements.

Buying A Telescope - Tips and How-To

!9# Buying A Telescope - Tips and How-To

[if ]
[endif]

A telescope can be the most expensive piece of metal and glass that sits on your shelf, or it can be your family's favorite toy. It all depends on how appropriate your decisions are when buying a telescope.

First, telescopes are not mere tubes with lenses at either end. Even the simplest ones are complex and relatively fragile, so they are not something to purchase until your children are mature enough to handle them with care.

Refracting telescopes are the simplest version. These scopes use precision-ground lenses at both the viewing end and the objective end (that's the big end), and also may use Barlow lenses and a mirror to increase the light-gathering quality of your telescope. The best refracting telescopes may have up to eight lenses throughout their construction. Overall, refracting telescopes have low maintenance and are excellent for clear viewing of planets and detail viewing. Look for the ones that have achromatic or apochromatic lenses. Apochromatics are better, but they are also significantly more expensive, sometimes by a factor of 10x the cost.

Reflecting telescopes are the ones that have much fatter barrels. That's because they depend on a well-cut mirror to collect light, rather than perfected achromatic or apochromatic lenses. While reflecting telescopes do a good job of gathering light so you can more easily view distant objects, they aren't as good as a quality refracting telescope for seeing small details on closer objects. For instance, the craters of the moon may not look as clear in reflecting telescopes, though you can see all the stars that make up the Pleiades without any problem. Newtonian reflectors have some of the detail problem corrected, but they still aren't perfect. And while refracting scopes need little maintenance, a reflecting telescope needs mirrors recoated every few years or it loses much of its light-gathering advantage. You may see high-end telescopes of this type marketed as Schmidt-Cassegrain.

There are a few other types of telescopes: the Ritchey-Chretien, which is a modified reflecting telescope; catadioptric telescopes, or compound scopes with elements of both refracting and reflecting types; and Schmidt camera telescope, a catadioptric scope designed specifically for photography. Because of price, most people opt for simpler refracting or reflecting telescopes for at least the first time out.

Selecting your telescope is not all you need to do; you must also select the proper mount, or tripod. The simplest is an alt-azimuth mount, which lets you move your scope up and down and left and right. More expensive are the equatorial mounts, which use alt-azimuth motion but also align themselves according to the earth's spin to make it easier to track heavenly bodies. The best mounts are the motorized equatorial mounts, which can be programmed to not just align themselves properly but even to find specific star bodies for you.

Next, look at magnifying power. This is not as important as you might think. Most telescopes come with eyepieces that provide higher magnification power. Don't pay attention to what the box says; instead, multiply the size in inches of the lens (on refracting) or mirror (on reflecting) of the scope by 50 to find out what the maximum useful magnification is, and depend on swapping out eyepieces to get your real magnification power. Lower magnifications are typically used much more than higher ones.

Larger telescopes in general, are better for viewing, but they are also more delicate. If you have a place where you're going to set up a permanent viewing station, it's worth it to get a large scope, but if you want high mobility, you should get a smaller good-quality scope.

If you live in a high-humidity area or a place where there are extremes of heat or cold in which you will be using your telescope, do not try to get away with a cheap telescope. Telescopes are very sensitive to both moisture and temperature, and your scope must be properly sealed to manage these extremes.

Finally, before buying a telescope, try to join a local astronomy club and check a few of the good ones out. Trying before you buy is always the best way to go, and you'll pick up lots of great tips from other club members in the process.

How Galileo's Telescope Created the Modern Science of Astronomy

!9# How Galileo's Telescope Created the Modern Science of Astronomy

[if ]
[endif]

Before Galileo turned his telescope toward the night sky the act of astronomy was pretty much an astrological pursuit where objects and motions of object in the sky were explained using ancient and archaic understandings of the universe and how it works.

But he didn't just observe and note new objects in the sky. He applied scientific methods, mathematical laws, and logical thinking to what he observed and it is this cross discipline approach that created the modern science of observational astronomy.

Galileo is often thought of as inventing the telescope. He didn't invent the telescope but he was the first person to turn one toward the night sky. And the observations he made created the new science of modern astronomy where telescopes are used to help us understand our universe, our place in it, and how it works.

Galileo first heard about the mysterious telescope in 1609 and set out to make a copy for himself. This first telescope magnified images about three times. And over the course of a decade Galileo continued to make more telescopes and his most powerful one magnified images about ten times. This telescope enabled him to see things never before seen. And it enabled him to change our view of the universe and of the objects in the sky.

The first thing that Galileo turned his telescope to was the moon and by observing it over the course of many nights he made an important discovery. He saw that dark areas on the surface grew and shrunk depending on where the moon was in relation to the sun. From this he made the correct deduction that these dark areas were shadows cast by craters and mountains. He further explained with geometry that the height of the mountains and depth of the craters could be correctly calculated. This was an astonishingly important revelation in our view of the universe because it was previously believed that the moon was a smooth surfaced object.

Another extraordinary observation, and the most important, that Galileo made was the discovery of the four largest moons around Jupiter. They were previously unviewable but with his ten-power telescope he could see them. And after viewing them over the course of several nights he observed that they moved. With further careful observation and calculation he proved that they revolved around Jupiter. And this was a universe changing observation because it was previously believed that everything in the universe revolved around the Earth.

Galileo went on to make many telescopes and to make many other important observations in both the night and day sky including the discovery of spots on the sun and the discovery of the rings of Saturn. His observations in the sky spurred on many other telescope makers and astronomers to further explore the amazing and mysterious objects in the sky. But more importantly he also spurred on other astronomers to apply the laws and lessons of mathematics and logic to their observations in a quest to understand how the universe works.

This creation of the modern science of telescopic astronomy was clearly born in 1610 when he published his work called "Sidereus Nuncius" or the "Starry Messenger". This work is still available to this day and is considered one of the most important written scientific works.

Features

When cell phones first came out, they were analog and now digital. Over time, the compact mobile phones come in various colors, and more features were added, such as cameras and applications.

As for telescopes may have had, or not so important to you. But some have more functions than others, so you must decide whatThey want out of your telescope. Do you want a telescope that is simple and easy, or that all types of functions that the viewing experience?

For example, the ETX-80AT-TC Astro Telescope Meade with multiple functions, including AutoStar. This is a computer controller that can find more than 1400 objects in the sky between the planets, stars, nebulae, and so on. For beginners, this feature could be really useful. More experienced users can not benecessary. But this is something to consider.

How far you want to see? Determine the size of the opening, so as you can see, some you can only view the solar system only. However, this may be sufficient for most people.
