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

[1913 Webster]Equatorial \E`qua*to"ri*al\, n. (Astron.)

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

(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.

exhibits objects inverted, which is not a hindrance in
astronomical observations.

Cassegrain, which differs from the Gregorian only in
having the secondary speculum convex instead of concave,

positions.

under Gregorian.

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.

and the smaller one near the open end) instead of an
object glass. See {Gregorian, Cassegrainian, Herschelian,
& Newtonian, telescopes}, above.

formed by refraction through an object glass.
