"Educators and astronomers have recognized Voyager as a powerful learning tool"

Version 4.5.7

My bad.

I thought the description said Astronauts, but it clearly said Astronomers.

I have used this program from the time it was called "Galileo II" on the Amiga.

Really excels in providing schematic representations of the heavens and real-time animations. Starry Night is no match here.

I have Voyager 4 on order, can't wait to start using it.

For other users: I have a large repository of settings files in my public folder on my iDisk (planeten.paultje@mac.com). This collection consists of all settings from previous Voyager versions I have used.
