This is a projection of the night sky into a sphere modeled with MATLAB R2016a, making a mashup of the crude sky and constellation maps from the NASA web site. The brighter the point in the surface lower is the radius in that point. I prefered this way insted of a direct bright to radius relation, because rendered like this will result in stars like spikes, that is will be difficult to print. You can notice the wide depression that it represents the Milky Way. It is inclined from the ecuator because the galactic plane is not in line with th Solar System's one, in which th map is referenced.
