public enum EquatorialCoordinateType
  Member nameValueDescription
equOther0 Custom or unknown equinox and/or reference frame.
equTopocentric1 Topocentric coordinates. Coordinates of the object at the current date having allowed for annual aberration, precession and nutation. This is the most common coordinate type for amateur telescopes.
equJ20002 J2000 equator/equinox. Coordinates of the object at mid-day on 1st January 2000, ICRS reference frame.
equJ20503 J2050 equator/equinox, ICRS reference frame.
equB19504 B1950 equinox, FK4 reference frame.
equLocalTopocentric1 Obsolete. Please use equTopocentric instead - see Astronomical Coordinates for an explanation.
In June 2018 the name equLocalTopocentric was deprecated in favour of equTopocentric, both names return the same value (1). The rationale for this change is set out in the Astronomical Coordinates section.
