Equatorial and Ecliptic Coordinates

Equatorial to Ecliptic Coordinates: The Earth equatorial plane tilts at approximately 23°26' to the plane of the Ecliptic (Earth's orbit about the Sun). Translating from one system to the other can be just a wee bit tedious, and fraught with peril for the unwary. Here is a tool to do this chore.
Right Ascension: Declination:
Ecliptic to Equatorial Coordinates: If you know the coordinates something relative to the Ecliptic but want the position expressed as a Right Ascension and Declination (the Equatorial coordinate system), here is the tool for you. It is, of course, the inverse of the tool to the left.
Longitude: Latitude
