Telescopes Telescopes are instruments used to magnify far-away objects, normally associated with Astronomy. True, telescopes are used widely in Astronomy. They are used to magnify celestial objects so far away from the Earth. The most powerful telescopes on Earth, the Very Large Array (VLT) array of telescopes in Chile, are so powerful that they can see the detail on a coin 80km away! Types of Telecopes There are three basic types of telescopes - Refractors, Newtonian reflectors, and Catadioptrics. All these designs have the same purpose, to collect light and bring it to a point of focus so it can be magnified and examined with an eyepiece, but each design does it differently. For more information, check out Celestron, a brand of telescopes.

Buying Telescopes If the thought of ever buying a telescope crosses your mind, please remember- do not buy those toy telescopes in departmental stores, you will be wasting your money. Instead, go for a small, portable 3-inch refractor for starters, which cost about $1200 from an established telescope agent. There are many online stores as well as a few stores in Singapore at places such as the Science Centre. Remember, telescopes are heavy investments, so please be sure of the limits and capabilities of any telescope that you want to buy before you do so. Besides the telescope itself, there is a wide array of utility equipment and acessories that you will have to get like oculars, star diagonals (reflect images so that they are easier to look through) as well as motorized mounts (to keep track of the stars as to ensure that they do not go out of the field of view due to the rotation of the Earth) Robotic 3 inch Refractor Telescope
