A lot of astronomical software can be found on the Internet. One of the main
FTP sites is the SEDS.LPL.Arizona.EDU
organization. It's next to impossible to review all the software that is
available. Here is but a very small selection.
Computer Ephemeris, part 1 of 2. A real MUST if you want to do your
own calculations. Positions and co-ordinates of Sun, Moon, planets and stars
from 1800 to 2050. Rise and set times, topocentric positions, sidereal times
and much, much more. Identical to ICE (Interactive Computer Ephemeris) of the
U.S. Nautical Almanac Office. Part 1: 182 Kb exe-file.
Computer Ephemeris, part 2 of 2. Part 2: 144 Kb exe-file.
