  Telescope \Tel"e*scope\, n. [Gr. ? viewing afar, farseeing; ?
     far, far off + ? a watcher, akin to ? to view: cf. F.
     t['e]lescope. See {Telegraph}, and {-scope}.]
     An optical instrument used in viewing distant objects, as the
     heavenly bodies.
     [1913 Webster]


  
     Note: A telescope assists the eye chiefly in two ways; first,
           by enlarging the visual angle under which a distant
           object is seen, and thus magnifying that object; and,
           secondly, by collecting, and conveying to the eye, a
           larger beam of light than would enter the naked organ,
           thus rendering objects distinct and visible which would
           otherwise be indistinct and or invisible. Its essential
           parts are the object glass, or concave mirror, which
           collects the beam of light, and forms an image of the
           object, and the eyeglass, which is a microscope, by
           which the image is magnified.
           [1913 Webster]
  
     {Achromatic telescope}. See under {Achromatic}.
  
     {Aplanatic telescope}, a telescope having an aplanatic
        eyepiece.
  
     {Astronomical telescope}, a telescope which has a simple
        eyepiece so constructed or used as not to reverse the
        image formed by the object glass, and consequently
        exhibits objects inverted, which is not a hindrance in
        astronomical observations.
  
     {Cassegrainian telescope}, a reflecting telescope invented by
        Cassegrain, which differs from the Gregorian only in
        having the secondary speculum convex instead of concave,
        and placed nearer the large speculum. The Cassegrainian
        represents objects inverted; the Gregorian, in their
        natural position. The Melbourne telescope (see Illust.
        under {Reflecting telescope}, below) is a Cassegrainian
        telescope.
  
     {Dialytic telescope}. See under {Dialytic}.
  
     {Equatorial telescope}. See the Note under {Equatorial}.
  
     {Galilean telescope}, a refracting telescope in which the
        eyeglass is a concave instead of a convex lens, as in the
        common opera glass. This was the construction originally
        adopted by Galileo, the inventor of the instrument. It
        exhibits the objects erect, that is, in their natural
        positions.
  
     {Gregorian telescope}, a form of reflecting telescope. See
        under {Gregorian}.
  
     {Herschelian telescope}, a reflecting telescope of the form
        invented by Sir William Herschel, in which only one
        speculum is employed, by means of which an image of the
        object is formed near one side of the open end of the
        tube, and to this the eyeglass is applied directly.
  
     {Newtonian telescope}, a form of reflecting telescope. See
        under {Newtonian}.
  
     {Photographic telescope}, a telescope specially constructed
        to make photographs of the heavenly bodies.
  
     {Prism telescope}. See {Teinoscope}.
  
     {Reflecting telescope}, a telescope in which the image is
        formed by a speculum or mirror (or usually by two
        speculums, a large one at the lower end of the telescope,
        and the smaller one near the open end) instead of an
        object glass. See {Gregorian, Cassegrainian, Herschelian,
        & Newtonian, telescopes}, above.
  
     {Refracting telescope}, a telescope in which the image is
        formed by refraction through an object glass.
  
     {Telescope carp} (Zool.), the telescope fish.
  
     {Telescope fish} (Zool.), a monstrous variety of the goldfish
        having very protuberant eyes.
  
     {Telescope fly} (Zool.), any two-winged fly of the genus
        {Diopsis}, native of Africa and Asia. The telescope flies
        are remarkable for having the eyes raised on very long
        stalks.
  
     {Telescope shell} (Zool.), an elongated gastropod ({Cerithium
        telescopium}) having numerous flattened whorls.
  
     {Telescope sight} (Firearms), a slender telescope attached to
        the barrel, having cross wires in the eyepiece and used as
        a sight.
  
     {Terrestrial telescope}, a telescope whose eyepiece has one
        or two lenses more than the astronomical, for the purpose
        of inverting the image, and exhibiting objects erect.
        [1913 Webster]

From THE DEVIL'S DICTIONARY ((C)1911 Released April 15 1993) [devils]:

  TELESCOPE, n.  A device having a relation to the eye similar to that
  of the telephone to the ear, enabling distant objects to plague us
  with a multitude of needless details.  Luckily it is unprovided with a
  bell summoning us to the sacrifice.
