I don't know if this would be any help, but here is a link to a lightwave tutorial on creating a starfield. It might at least give some ideas....

I have done his entire series on this site with Lightwave and it looks awesome (even the nebulas using Photoshop).

Would there be a way to duplicate this process in Maya somehow??

Good luck,
