Skyglobe
A favorite of mine, although Skyglobe is a really old (1993) DOS-based program, it is by far the best little planetarium I have ever played with. During our six years of cruising I had it loaded on my laptop computer and used it often—to get sunrise and moonrise information and to identify stars and planets in the vivid nighttime skies.
It’s easy to use and runs flawlessly under every version of Windows I have ever tried. Though I haven’t tried Vista, I expect it will work there as well.
Everything is in the .ZIP file. Just unzip to its own directory and double-click the .EXE. It resides in its own directory and has no hidden crap and no effect on Windows registries and the like. Uninstall just delete the directory and/or files.
Note that this fully functional little product is currently described as “Shareware”. Information is included on the splash screen.
