 Definition: 
  1. \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.
    
    
  2. \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}.
    
    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.
