Mirror Telescopes
Reflecting telescopes are the ones who use the telescope mirror to bring the picture to you. Do you love stargazing and hope that you can get a closer view and more living creatures in the galaxy? So what you need is a telescope. You can place your telescope on your porch or near a window, and you will have an unobstructed view of the night sky.
If you are motivated, you can even create your own telescope with the right resources. All you need are mirrors with concave spherical profile, the light from stars that are reflected to a focal point to generate radiates.

Types Of Telescopes For Astronomy
Drawings telescope
The job of a telescope is to collect light, not (not the eyepiece that job), an image to enlarge. The biggest target (the part that collects the light), if a lens, in refractors, reflectors or mirrors to gather the more light the telescope. The more light you gather more details, will capture you be able, and also important for astrophotography, the shorter the exposure time, you must be in order to capture these details.
Refractors
The type of telescope imagine most people, if it is to hear the word telescope “refractor. This is what Galileo for his break-thru uses discoveries. A telescope has a lens on the front that just the light passes through the back of the tube, focusing this light to an eyepiece or camera for astrophotography.

History of the Telescope and Binoculars
Before we trace the history of binoculars and telescopes, it is good that we define what is the meaning or binocular telescopes. Binoculars are optical instruments. As we all know, optical instruments, an enlarged view of the objects that are at a remote place or region. A telescope is an optical instrument that allows direct observation and photographic recording of objects that are in a remote location. A telescope can emit, transmit and reflect the visible radiation.
Comparisons between a telescope, which is one of binoculars when it comes to viewing remote viewing course, best when both eyes are used. With binoculars, the perceived color and contrast is improved by almost 40%. It is more convenient for some people remain much longer in order to a specific instrument with two eyes as compared to using a telescope with the use of an eye. A telescope uses a tunnel vision and a single barrel during use stereo vision binoculars eliminates fatigue in his eyes.
Telescope and other instruments such as optical alignment of the interferometer telescope, binoculars, autocollimator, test, camera, camera software and test patterns are extremely important in science studies today. In fact, contrary to popular opinion, the first telescope was invented by Galileo. The idea originated with Hans Lippershey and after Galileo heard that the patent was rejected, has re-invented the “mirror” as a toy, with the celestial body is observed to appear.
