I've been buying the Starry Night software since before it was called starry night. This copy was bought simply because I'd changed from a PC to Mac computer. The Mac version is no different from the Pc version - in both cases, just great software.
You can quite easily set up you own location so that the stars shown on the screen are exactly as you will see them live from your own back garden. If you visit the web site, there's even a help file to show you how to use photos of your own back garden as the basis of your screen display - how neat is that?
The program also shows satellites, information on stars and distances to them as well as a continuously updating azimuth information. You can zoom to visit stars/moons/galaxies or (this is fun) click on a button and fly, as in a spaceship, around the solar system or even travel outside it.
Educational as well as fun to use - what more could you want.
