If you're looking for a dual-purpose telescope appropriate for both terrestrial and celestial viewing, then the AstroMaster Series is for you. Each AstroMaster model is capable of giving correct views of land and sky. The AstroMaster Series produce bright, clear images of the Moon and planets. It is easy to see the moons of Jupiter and the rings of Saturn with every one of these fine instruments. For views of the brighter deep space objects like galaxies and nebulae, we recommend the larger aperture and light gathering ability of the Newtonian reflectors.

Although Galileo has historically been credited with the invention of the refracting telescope in the early 1600s, credit should be given to three eye doctors whose work helped him develop the theory of refraction for his telescope. Refracting telescopes are very simple and have only two main components -- a convex lens called the objective lens, and a concave lens that makes up the eyepiece.

The convex lens is located at the end of the telescope and serves to refract or bend the light that enters the telescope and turn it into a single beam of light. Then the image you are looking at shows up in reverse on the concave lens, which turns the image around. Refraction telescopes allow the viewer to see very bright and clear images.

The refracting telescope invented by Galileo is used today by many people but the drawback is the small field of view it offers. A well known refracting telescope is the one in California at the Chabot Space and Science Center. The center actually has two refracting telescopes -- an eight-inch refracting telescope and a 21-inch refracting telescope. They are very basic telescopes and therefore spherical aberrations can occur. One way these aberrations are dealt with is by using a pair of lenses (a convex and a flat lens) to create an achromatic lens.

Refracting Telescopes and Color

One of the most common issues with a refracting telescope is the separation of light that occurs when the light is bent. When this happens, it is called chromatic aberration and it can be remedied with the use of an achromatic lens.

One problem with large refracting telescopes is getting the lens large enough without any imperfections that will be picked up as light goes through the lens. There are 41-inch lenses but they are unusable. Refracting telescopes are generally not used by professional astronomers due to the issue of getting all the light to focus in on one place at the same time.

Refracting telescopes are popular among novice astronomers and are utilized at observatories around the world. It is a good telescope choice for beginners due to the lens being enclosed that makes the image appear to be less shaky and have less movement than reflecting telescopes, which send the image to the viewer's eye from a mirror. The process of reflecting light from the first mirror to the second and then the eye piece can cause an unsteady image.

Through the study of electromagnetic emissions, astronomers hope to better understand the universe to come. There are many mysteries of the universe, which are only possible by comparing the images of telescopes for the wavelength to capture only a specific portion of the electromagnetic spectrum can be resolved. And 'it is often necessary for astronomers to study images from various telescopes on celestial phenomena.

Various kinds of telescopes usually do not takesimultaneous measurements. Space is a dynamic system, a photo taken at one time is not automatically the same exact image of the same event at a later date taken. And often, there's just enough time for a kind of telescope to examine phenomena such as extremely short-lived gamma-ray bursts. They are doing additional telescopes on the object, he grew too weak to be felt.

Telescopes rely on communication between energy and matter. The atomicRole that the telescope has somehow built forms of energy generated by the field of astronomy. This energy is in the form of electromagnetic waves. Even though the original telescope was founded 400 years ago, we did not have a complete picture of the electromagnetic spectrum in the first part of this century. As our information of the physical improves, scientists are able to develop ever more advanced telescopes. But as technology advances and becomes more specific, the differenceshighlighted in the design telescope.

Almost the entire universe is invisible to us, because we only see the light. If the majority of the people who think of telescopes, to think of the observed light or visual, telescopes. There are different types of telescopes to help astrologers to study the universe, ranging from the X-ray telescopes, infrared telescopes. Each type of telescope will show a different view of the same phenomenon.
