The Star Map Crystal is a glass cube that's been laser etched with a 3D map of our nearby stars. Sol is in the center, and the map covers 5 parsecs in all directions, which is as far as Altair. The map comes with a key describing each star and symbol.
Whether you're an astronomer learning to see the sky in 3D, a science fiction reader, a citizen of a spacefaring civilization, or just like to know where you stand, the Star Map is essential equipment. Don't leave Earth without it!
This way to the galactic core.
