Reflecting Telescope Facts

Reflecting Telescope Facts
A reflecting telescope is one that causes an image to reflect at a focus point by using mirrors. It was invented during the 1680s by Isaac Newton. These telescopes improved the before used refracting telescopes by giving a clearer picture. Reflecting telescopes also allow larger objects to be seen and are therefore ideal for studying objects in our Solar System.
Interesting Reflecting Telescope Facts:
Reflecting telescopes are also called reflectors.
Most telescopes used by astronomers today are reflectors.
In Newtonian telescopes, one mirror is used to capture the image while another mirror is used to reflect the image from the first mirror.
Most common reflecting telescopes are a variation of the Newtonian telescope.
Reflecting telescopes are better than refracting telescopes because they have a much clearer picture and are cheaper to make.
The Hubble Space Telescope is the largest space reflecting telescope.
The largest size of any one mirror in a reflecting telescope can vary and have reached lengths as high as 10 meters.
Although reflecting telescopes are more economical, refracting telescopes are better for beginning users.
Some reflecting telescopes are so large that the observer can actually sit inside of it to make observations.
More than one reflecting telescope can be combined together to make one large, super telescope.
The largest reflecting telescope in the world, the Gran Telescopio Canarias, is in Spain.
The Gran Telescopio Canarias has a mirror that is more than 30 feet in diameter.
There are currently three larger reflecting telescopes in construction that will be much larger than any that exist today.
The biggest disadvantage to using a reflector is that the optics often requires lots of maintenance.
While Newtonian telescopes are often used for space observation, the Gregorian telescope is best for land observations.
