Equatorial
(gcide) | Equatorial \E`qua*to"ri*al\, a. [Cf. F. ['e]quatorial.]
Of or pertaining to the equator; as, equatorial climates;
also, pertaining to an equatorial instrument.

Equatorial
(gcide) | Equatorial \E`qua*to"ri*al\, n. (Astron.)
An instrument consisting of a telescope so mounted as to have
two axes of motion at right angles to each other, one of them
parallel to the axis of the earth, and each carrying a
graduated circle, the one for measuring declination, and the
other right ascension, or the hour angle, so that the
telescope may be directed, even in the daytime, to any star
or other object whose right ascension and declination are
known. The motion in right ascension is sometimes
communicated by clockwork, so as to keep the object
constantly in the field of the telescope. Called also an
equatorial telescope.
[1913 Webster]
Note: The term equatorial, or equatorial instrument, is
sometimes applied to any astronomical instrument which
has its principal axis of rotation parallel to the axis
of the earth.

Equatorial telescope
(gcide) | 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.
