Izzy's Skylog is an easy to use freeware guide to learning the constellations. All 88 star groups are featured, each on its own page.

It was written specifically to show the constellations as they are oriented and as you seen them in the night sky.
You can get information about each constellation, such as where and when to look the sky, mythological backgrounds etc...

It works fine with Win 95/98 and it is tested on windows XP.
