Telescope (Telescopes)Even though the eye of the people, we can see the sky, but using binoculars or a telescope types will allow the eyes we can get even more exposure. See a darker or brighter or more clearly dimmed. Telescope (Telescopes) is a device to help see the stars one of the star-watchers can help study the sky more than binoculars.Warning!!!Do not use binoculars or a telescope, the sun shines or the direct light of the Sun which is decisive because it has a high contrast to make blind immediately.What kind of telescope telescope types are divided into three. 1. the light refraction telescope (Refractor Telescope). The main telescope is a refraction of light through lenses object (Objective Lens) and refraction through a lens, once again eye (Eye piece) this type of camera. Discovered before Galileo will be developed and widely used until. In the days of Galileo, which is perfect for exploring the surface of the Moon, the planets, and rings of planets, stars etc.The advantage of light refractive telescope design is ideal for the beginner because of the cheap and because it does not want anything too much. Makes maintenance easy. In addition, the structure of the camera, it prevents dust. The disadvantage is that the maximum size of an object. Which is about 3-5 inches in size, and is therefore unable to perceive the object fade lens size is also very much an object that big would make images that have color distortion? 2. reflex optical telescope (Telescope Refrector.) The main telescope is a reflection of the light curve (Concave Mirror Objective) to ceiling glass and refraction through a lens, once again eye (Eye piece) this type of camera, developed by Newton, ideal for exploring the saek cluster, Nebula, object, the sky or the Galaxy quite pale, etc.The advantages of a reflective telescope is ideal for General because the image has a very high quality, not price. In addition, life-like images. In addition, the size of the camera, which is important to get light. This type of camera has a size greater than. The second is the mirror reflection (Secondary Mirror or Reflecting Mirror) inside the camera that the lens of the eye, then the mirror will reduce the exposure of the camera space. Cause when the size of the camera. The camera light to light refraction. Make a picture of the object and the camera also semitransparent shade requires particular care to prevent dust or water-holding, because in front of the camera. Turn out the light directly, nothing comes close. 3. a Catadioptric telescope (Catadioptric Telescope). A telescope that relies on both the reflection and refraction of light with this type of camera used, curved mirror reflection and refraction of light in lenses and cameras of this type as 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 a telescope, there is a small movement to make the size of the camera, making short track star motor installation is simple because the weight balancing and installation equipment. The disadvantage is the price that is higher than the other cameras and images. Have a sharp yet reflective image back, not left to Java?
