Getting to Know Your Beginner’s Telescope

by trg

The most common mistake people make regarding telescopes is that they believe telescopes are made to “make objects appear closer or bigger”. This is perhaps true in some cases, as there are telescopes whose main function is to basically magnify images. But the true purpose of telescopes is to actually gather light in order to be able to view objects where light is pretty scarce. Think about it, objects in outer space are difficult to see from where we are because aside from the fact that they are too far from us, there also isn’t much light that reaches us to see them as well. As such, it doesn’t matter how powerful your telescope’s magnification is; if it doesn’t gather enough light, you still wouldn’t be able to see much with it.

The more light a telescope gathers, the brighter and clearer the object would appear to be. This is why one major factor to consider in purchasing the best telescope for beginners would be the aperture. The aperture is the part of the lens that allows light to illuminate the object through the scope lens. The wider the aperture, the more light is casted on the planet, star or whatever celestial body you wish to see through your telescope.

Aside from this, you also need to know of the types of telescopes out on the market. This will also help you understand how a telescope works, especially if you’re someone looking to purchase a telescope for beginners. There are mainly three types of telescopes, both with their pros and cons, of course, and to make your decision on what type of telescope to buy, you should understand how all three work and how they would affect your stargazing.

Refractor Telescope – A refractor telescope gathers light with lens on one end, focusing it on the eyepiece all the way at the other end. These have the potential for the clearest image as there are no light obstructions. However some discoloring might become visible through a refractor.

Reflector Telescope – Invented by Sir Isaac Newton Himself, the Newtonian scope Is usually the cheapest telescope and gathers light through mirrors in its body. NO color problems in this one, however it is more prone to contrast loss than the other types.

Schmidt Cassegrain Telescope – The Schmidt Cassegrain telescope, on the other hand, utilizes both technology of lenses and mirrors. Its advantages include being compact, and are cheaper than refractors.
