PS
Paul Schlyter mentions an iteration method (with which I
am not familiar) and iteration is the key to performing many
these calculations from Meuss. *You can bypass many
of the formulas he gives by simply iterating conjugate (+/-)
terms and get more accurate results!*

This is especially true of rising/setting/transit calculations
or in dealing with planetary distances at oppositions.
The calculations dealing with Kepler's formula require
several iterations which are easily accomplished on
Excel by extending the iterations with a mouse click
and drag.

Do a few cell entries *every day* and in a couple of months
you will have most of Astronomical Algorithms in place and
functioning.
