subject: Look To The Stars With A Newtonian Reflector Telescope [print this page]


If you are an astronomer or just someone who is fond of staring at the stars in the sky at night, you must have been wishing to have a telescope of your own. It is in fact very easy to say that you are going to purchase a telescope soon, but the fact is that it is quite a challenge to figure out what kind of telescope one would need. One of the most popular choices in telescopes is the Newtonian reflector telescope.

The difference between Newtonian reflector telescopes and other telescopes is their utilization of mirrors instead of lenses to create light and enlarge images. Because these telescopes use rounded mirrors it's unlikely that spherical as well as chromatic abnormalities will arise. This basically means that images are clearer for the astronomer.

The Newtonian reflector telescope is also the first successful kind of telescope. At the lower part of the tube you will find the curved primary mirror. The primary mirror's reflects through the cylinder to the secondary mirror at the top. To focus on an image, the telescopic should be pointed towards that direction and the flat secondary mirror positioned at 45 degrees.

A popular telescope, the Newtonian reflector telescope is also named after its well-known inventor. If you haven't guessed already, the inventor was great Sir Isaac Newton. With the quality that this telescope has, it is actually surprising that it comes at a very reasonable price.

This telescope has many advantages but it does have a slight disadvantage, in that it needs regular alignment. Maintenance is also required from time to time to keep mirrors dust and smudge free for better viewing. This is indeed more demanding than the other types. Some other telescopes available are the Schiefspiegler, Yolo, Herschelian, Cassegrain reflector as well as the Gregorian reflector.

Keep in mind when you purchase your own telescope, whether it is a Newtonian reflector telescope or any of the other types, it is important that you know the products' good and bad points. Take time to do some research so that you can make sure that you will be getting the most out of your investment.
