Telescope (Telescopes)Even if a person's eyes, we could see the sky, but using the device category binoculars or a telescope will allow an eye, we can get even more exposure. Make visible the object with darker or brighter or more obvious pale. Telescope (Telescopes) is one of the categories to see aid star allows students see stars can learn the sky more than binoculars.Warning!!!Do not use binoculars or any telescope mirror or looking to the Sun directly marketed because of light of the Sun, which has a high contrast to make blind immediately.What kind of telescope telescope into 3 categories: 1. the light refraction telescope (Refractor Telescope) The telescope is relying on principles of refraction of light through lenses object (Objective Lens) and refraction through a lens, once again eye (Eye piece) this type of camera. Before the discovery, Galileo will be developed and used widely until. In the days of Galileo, which is perfect for exploring the surface of the Moon, planets, stars, and rings of planets, etc.The advantage of the light refraction telescope is ideal for the novice, because cheap and because it does not want anything too much. Makes maintenance easy. In addition, the structure of the camera, it prevents dust in the already exists. The disadvantage is that the maximum size of an object is not much. Which generally is approximately 3-5 inches, and is therefore not capable of observing objects that are also very pale, the size of a large object lens makes the image have color distortion. 2. reflex optical telescope (Telescope Refrector) The telescope is a living reflection of light with floor to ceiling glass, curved (Concave Mirror Objective) and refraction through a lens, once again eye (Eye piece) this type of camera, developed by I-saek Newton is ideal for exploring the cluster, Nebula, object, the sky or the Galaxy quite pale, etc.The advantages of a reflex optical telescope is ideal for General because images have good quality, the price is not very high. In addition, images that were realistic. In addition, the size of the camera, which is important to get light. This type of camera has a size greater than. The disadvantage is that the second reflection mirror (Mirror Mirror Reflecting or Secondary) within the camera serves the eye lens, the mirror will be reducing exposure of the camera. Cause when the size of the page the same camera. Light refraction model camera to pick up more light. Make the picture of the object and the camera, semitransparent shade requires particular care to prevent dust or water down, because the front of the camera. Turn off direct light, nothing comes close. 3. a Catadioptric telescope (Catadioptric Telescope) A telescope that relies on both the reflection and refraction of light together for this type of camera that uses both curved mirror reflection and refraction in lenses and cameras of this type is called a "Catadioptric" means glass-lens (mirror-lens) this type of camera is ideal for exploring the cluster, Nebula, object, the sky or the Galaxy quite pale, etc. The advantages of this kind of telescope to make smaller movements, and the size of the camera makes a short track star motor installation is simple because the weight balance and install device consisting of. The disadvantage is the price that is higher than the other cameras and images. Reflective yet sharp did not have images from the left to Java.
