From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Telescope \Tel"e*scope\ (t[ecr]l"[esl]*sk[omac]p), a.
      Capable of being extended or compacted, like a telescope, by
      the sliding of joints or parts one within the other;
      telescopic; as, a telescope bag; telescope table, etc.

From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Telescope \Tel"e*scope\, n. [Gr. [?] viewing afar, farseeing;
      [?] far, far off + [?] a watcher, akin to [?] to view: cf. F.
      t[82]lescope. See {Telegraph}, and {-scope}.]
      An optical instrument used in viewing distant objects, as the
      heavenly bodies.
  
      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.
  
      {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,
            [and] Newtonian, telescopes}, above.
  
      {Refracting telescope}, a telescope in which the image is
            formed by refraction through an object glass.
  
      {Telescope carp} (Zo[94]l.), the telescope fish.
  
      {Telescope fish} (Zo[94]l.), a monstrous variety of the
            goldfish having very protuberant eyes.
  
      {Telescope fly} (Zo[94]l.), 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} (Zo[94]l.), 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.

From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Telescope \Tel"e*scope\, a. [imp. & p. p. {Telescoped}; p. pr. &
      vb. n. {Telescoping}.]
      To slide or pass one within another, after the manner of the
      sections of a small telescope or spyglass; to come into
      collision, as railway cars, in such a manner that one runs
      into another. [Recent]

From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Telescope \Tel"e*scope\, v. t.
      To cause to come into collision, so as to telescope. [Recent]
