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

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.

You're just a freak night sky clear and want to deepen your knowledge of astronomy must take as Galileo? All you need is a vision of 20/20 and an astronomical telescope clear and reliable for your astronomical adventures to a great start.

Two of the biggest names in the production of world-class telescopes of the Meade and Celestron are. Together with the main producers of this great star gazing aides Meade and Celestron wereprovides consistently clear and good ways of learning to help them explore the vast and mysterious universe.

Meade Telescopes are a number of series of high-tech telescopes like the Meade DS-2000, and Meade ETX Meade ETX-PE Meade ETX-LS, Meade Lightbridge, Meade LX200-ACF Meade LX200-ACF Advanced, with Meade LXD75, and more again, providing it is a relatively clear, single, tour Universal Service in the night sky is clear.

Most of the Meade AstronomyThe devices are equipped with an onboard computer, which automatically when the professor of astronomy that actually execute successfully on planets like Jupiter and Saturn, nebulae, galaxies, star clusters and the most gifted. These Meade to give careful consideration to small things and items such as premium quality glass optics, optical coatings high transmission of large primary mirror and engineering tolerances, from which his clear difference in the clarity,Resolution and contrast. If you doubt the power of the telescopes of small and medium enterprises appear to have Meade has a number of large telescopes that can be used anywhere. While enormous size, these telescopes provide high-quality optics with ultra portability and about the same price as other classic Meade.

Celestron Telescopes on the other hand, are ideal for beginners and advanced astronomers significantly, with a wide selection of reliable series of telescopesCelestron SkyScout Scope 90 Telescope Celestron such as Advanced Series Celestron AstroMaster, Celestron CGE Celestron CPC Celestron NexStar SE, and much more.

Celestron telescopes are easy to use and manage, as they are virtually maintenance-free for free, but with high precision optics. Celestron has a number of telescopes, which are ideal for both celestial and terrestrial viewing. Celestron has also IT-types that are scheduled to be fully informed of all the universe.If you're one of those who want to have to catch the satellites in Earth orbit to the telescope, Celestron telescopes have, which are equipped with GPS receivers that will help you the exact location of these satellites on the earth. Celestron also offers these types with the classic orange tube-shaped appearance of the original technology of 21 century, such as coatings higher operating system is completely computerized, flash upgradeable hand control and are more inspired.

For beginners andExperts in astronomy, Meade and Celestron are one of the most prestigious and reliable quality for telescopes to consider to help us explore the vastness of the universe. It will not make any concern that you could spend on something that will not be able to know how this great look at the stars aides were perfectly designed for all types of users were.
