catadioptric telescopes use a combination of curved lenses and mirrors as objectives to collect light. they are good for all-around viewing because they have the attributes of both refractors and reflectors.

Astronomical telescopes do not correct the inversion of the image. Refracting telescopes are cheap if small, but limited in size because it is impossible to make very large lenses, due to the weight of the glass involved. They are also subject to chromatic abberation. Reflecting telescopes are lighter, but require a 2nd mirror to reflect the light to the eyepiece, this always has to be placed in the optical path of the primary mirror, causing some loss of light and image quality.<br><b>References : </b><br> Terrestial Telescope are for seeing objects on Earth, and correct the inversion of image.
