Hows about are you trying to accomplish this?  If it involves and array,
I can already tell you that you're probably not going to get the results
you are looking for (not to mention taking up alot of memory that isn't
needed.)

You may want to try this.  Draw the stars in a color that isn't used for 
anything else within the starfield.  Then, move around the screen, from the
inside out, looking for screen pixels with this color.  Then, simply put
the color back (to black) and draw the star at the same angle away from the
center at a slightly longer distance....

I hope this helps.  Although it may require a half-way decent graphics
package to get good results.

Tim.
