What are the different uses for different types of telescopes [refracting, reflecting and catadioptric?]
refracting Telescopes are used to examine the visible-light region of the electromagnetic spectrum. typical uses include viewing the Moon, other objects of the solar system such as Jupiter and Mars, and double stars
the reflecting telescope is commonly used in Astronomy because it is much easier to create a large convex mirror than to create the huge lenses that would be necessary to gather the light to see dim far-away objects
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.
Terrestial Telescope are for seeing objects on Earth, and correct the inversion of image.
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.
