I just came across a brilliant program, downloadable from
http://www.skycalendar.com/
This is a program for tracking our planetary system. Very user-friendly, and pilots....Itīs FREE. Check it out chaps, it's very good. When flying at night, no matter where you are, if you see a light above the horizon, not a plane, not a bird, and not anything wearing the underpants on the outside, check the Sky Calendar and instantly know the name of that star or planet. Many different features in this as well as good graphics.
