For science fiction books and computer games, it's handy to have a science fiction world map that showcases a planet and its moons, a solar system, or even entire galaxies. Currently it is possible to make a solar system with textured spheres, but it's quite inconvenient.
A star map would have stamps of different types of stars (and even binary stars!), planets, moons, asteroids, planetary rings, and the like. Some other features would include spacecraft, space stations and giant space creatures. Some backgrounds could be galaxy or deep space images.
For large scale maps, some galaxy stamps would be great! That way you could have a map of a galaxy cluster or organize your galaxy into multiple main fractions with notable star systems in each.
