Different types of Celestron Telescopes

Refracting telescopes have an objective lens at the front of the tube. The light exits out through the back of the tube to the eyepiece. Since many observations are made high in the sky, a right-angle diagonal is used to avoid neck strain. This also provides an upright image making them suitable for terrestrial observations. A refractor has several advantages over other designs. The tubes are enclosed so that dust and moisture do not enter the tube, they have fixed optics that does not normally require collimation, and they do not have a central obstruction which reduces the light entering the tube. Then you have Catadioptric telescopes optical telescopes that combine specifically shaped mirrors and lenses to form an image. This is usually done so that the telescope can have an overall greater degree of error correction than their all lens or mirror counterparts with a consequently wider aberration free field of view. Their designs can have simple all spherical surfaces and can take advantage of a folded optical path that reduces the mass of the telescope, making them easier to manufacture. The aperture of a telescope is several times larger than the aperture of human eye so that the objects that cannot be normally seen by unaided eye can be seen. Light- gathering power of a telescope is proportional to the area of its aperture and hence depends on the square of the radius of the mirror.

A telescope can be equipped to record light over a long period of time, by using photographic film or electronic detectors such as photometers or CCD detectors while the eye has no capability to store light. And a third major advantage of large telescopes is that they have superior resolution, the ability to discern fine detail. The resolution is directly proportional to the wavelength being observed and inversely proportional to the diameter of the telescope.

They both work in different ways so it will be up to you on which one you decide to get, you can use this as a hobby and look at the skies with your kids and the whole family or you can do it alone. And end up find out something that no human kind has.
