This Addon is for Celestia v1.5.0 prerelease3 or later. It provides a 3D model of a balloon-borne gas-Cherenkov gamma-ray teleseope.
Celestia is a free, real-time, 3D space simulation. You can use it to view our Solar System and the surrounding stars from any viewpoint you like -- from the surface of the Earth, from outside the Galaxy, or trailing along behind the Cassini Saturn probe. Half of the fun is contributing your own efforts to improve the environment it provides. Celestia runs best on a computer that includes a 3D graphics card, but it'll also work on a computer that does not have one.
More information about Celestia is available at the official Celestia Web page at http://www.shatters.net/celestia/ or Selden's unoffical page at http://www.lepp.cornell.edu/~seb/celestia/index.html.

This Addon shows a balloon-borne gas-Cherenkov telescope observing the Crab Nebula from an altitude of 100,000 feet above Palestine, Texas. The exernal skin has been made translucent in this model so you can see the internal structure of the telescope. The actual telescope was enclosed in a bag composed of fiberglas cloth and an opaque layer of neoprene rubber.
