Download SkyGazer 4.5

You can download an unregistered copy of SkyGazer 4.5 and test-drive it before buying. The downloaded version is identical to the version that we ship on CD-ROM. However, until you register your copy, SkyGazer will only display a small portion of the objects in its database, and will not recieve data or program updates. Check out the Getting Started pages in our Support section for a guided tour.

If you have already registered your copy of SkyGazer 4.5, save the "Registration.txt" file inside your old SkyGazer 4.5 folder. Copy it into your new SkyGazer 4.5 folder to avoid having to register the new version again.
