because i am working on my spacebug project, i also needed starts.
I finaly came up with something simmilar, it uses the bozo patern.
However this was only to have a quick testrender background. I think your
method is better.this is the code:

#declare Stars=
texture{
   pigment{
      bozo
      turbulence 1
      color_map{
         [.00 rgb 3]
         [.25 rgb 2]
         [.11 rgbt 1]
         [.99 rgbt 1]
         }
      scale .007                             //.005
      }
   }

sphere{
   0, 10
   hollow
   texture { Stars }
   scale 10000
   }


you can see my spacebug with those stars (both in progress) at
