Try using my starmap include file... I hav attached it to this post... If 
the attachement hasn't survived, you can download it from 
http://www.rarius.co.uk/starmap.inc

There is an example made with it on the illustration page of my website 
http://www.rarius.co.uk/

All you need to do is define a macro and then include the file...

#macro Star(vPosition, fMag)
    sphere
    {
        vPosition
        6-fMag
     }
#end

#include "starmap.inc"

The vPosition parameter is the star's position at a unit distance from the 
origin.
The fMag is the star's magnitude. It ranges from -1.1 to about 6

You can of course make the macro more complex... there is an example at the 
top of the incude file itself...

The include file calls the Star() macro 9000+ times. Once for each star.

I compiled the include file using a simple VB program from the Bright Star 
Catalogue, so it has every naked eye star on it.
