To explore the universe of Orion's Arm first download the free programs and addons on this page Orion's Arm Addons Page 1.
Now we have the basic package, we can add some of the Megastructures, and some high-res textures for colony worlds made by John M. Dollan and other contributors.


---------------------------------------------------------------------------

Clickable Location Links

The easiest way to explore the Orion's Arm Celestia Addons is to click on a preset Cel:URL link, which will take you to a preset destination within Celestia. Note that Celestia Cel:URLs will not work properly until you have downloaded both Celestia and the appropriate addons.

Tip: you can have several different versions of Celestia on your system if you like, each with different sets of addons. If you have more than one version of Celestia these links may open the wrong version. So to ensure the links work correctly open the correct version of Celestia first. If you have only one version of Celestia. opening it first will help speed it up in any case.
