Newtonian Reflector Telescope

Newtonian Reflector Telescope

Whether you are an astronomer or just an ordinary person who loves looking at the sky and staring at the stars, you would surely have been dreaming to have your own telescope. So many people say they are planning to purchase a telescope, but they just have no idea what kind of telescope to choose. In fact, the Newtonian reflector telescope is one of the hottest items on the list of telescopes to buy. But do you know what a reflector telescopes are?

These are the telescopes that use mirrors instead of lenses, to obtain light and magnify a subject or an image. What is good about using curved mirrors in telescopes is that both spherical aberration and chromatic aberration are not likely to occur. This will then result in the telescope being able to catch more wavelengths that will produce better quality images for the viewer.

The Newtonian reflector telescope is the very first successful telescope of its kind. You can see a curbed primary mirror at the bottom part of the tube, which focuses the mirror and reflects it back towards the top of the telescope where there is a second mirror which is flat. You would turn this secondary flat mirror at a 45 degree angle and aim the image to the eyepiece mounted on the side of the telescope tube.

Newtonian reflector telescopes are actually more popular than other types of reflector telescopes. First created by Sir Isaac Newton, this awesome telescope is very favorable as it is reasonably priced considering the quality that it brings. However, there are still, of course, some disadvantages to this type of telescope.

First is that a Newtonian reflector telescope requires alignment on a regular basis. In addition, because this telescope employs mirrors, it has a need for more complicated cleaning method for the mirror as compared to others. Some of the other types of reflector telescopes are the Gregorian reflector, Cassegrain reflector, and the Off-Axes designs (Herschelian, Schiefspiegler, Yolo).

Meanwhile, when purchasing a reflector telescope, whatever the kind you choose, you will have to first be aware of the advantages and disadvantages of all the types available. So you had better spend some time and effort in doing some research. Keep in mind that a telescope, however cheap they may say it is, is still quite an investment. This is why it is important that you be sure you will only spend your money on something that you will truly enjoy and fully get the advantage from.
