Observation Transforms
This transforms coordinates between
horizontal (observer),
equatorial
and
ecliptic
coordinate systems.
After a location and a time are entered for the observer's location,
changes to any one of Observation Direction fields will update the
others.
For example,
enter Sirius' RA
6:45:08.9 and Declination -16:42:59 in the equatorial coordinates
and the ecliptic and horizontal values will update to match.
