I was looking at Orion last night for the fisrt time through binoculars and notice dual stars. At first I thought it was the Binoc's doubling the image, then I realized it was his sword belt. I haven't seen it with the naked eye yet, to the nature of the 2 sets of "dual" stars got me to wondering how far apart they were, distance wise. I looked it up in Cartes du Ciel, and it gave me distance for those stars from earth. So I started looking for a 3D map of the stars. Google returned nothing really useful.
Does anyone know if one is available? Has it been done?
I would like to find a 3d model of the universe, If possible, one where you could view the known stars from different perspectives, say in increments of 1 light year jumps.
