Notes:
The
gif files were generated from the free planetarium
software package Cartes du Ciel.
I
found the planetarium software by entering the search terms "planetarium
software" into a Google search.
This led me to the following first hit: http://astro.nineplanets.org/astrosoftware.html
which lists planetarium programs for various platforms. Under "Windows" I
picked the first "free" package,
"Cartes du Ciel", downloaded and installed the complete package 2.76
(15 MB) and was up and running in minutes.
It is amazingly comprehensive and intuitive!
