Getting Started with Voyager 4.5 and SkyGazer 4.5

Registering and Updating

You'll be asked to enter your serial number and register your software the first time you launch it. This unlocks the program's full database, and requires an internet connection; if you don't have an internet connection, we can register you over the phone. You can register the same serial number on up to two machines, and re-install/re-register an unlimited number of times on the same machine.

After registering, Voyager and SkyGazer will ask if you wish to update your asteroid/comet/spacecraft data, and/or check for program updates. We suggest that you do this monthly; it will ensure that your solar system object positions are accurate and up to date.

Downloading and importing asteroid data may take a few minutes, since there are so many known asteroids (over 400,000 as of this writing!). Importing comet and satellite data should only take a few seconds, however.

Please note: if you get a "failed to download" error message while updating, the Minor Planet Center and/or Celestrak web sites may be down; these are where Voyager and SkyGazer get their asteroid/comet/satellite orbit data. If this happens (which is rare!), just try updating again later. You can also un-check the "Asteroids", "Comets", and "Spacecraft" options if you only want to download program updates.
