| 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. |
