Star Field Techniques -

I have a technique that I use to lay down the base of a star field a la Greg Martin, but it doesn't work at high resolutions. Because it uses noise, which can't be natively scaled, it only works at fairly small resolutions, which I've historically just scaled up and hoped for the best.
That works to an extent, if the scale is less than one order of magnitude, and the star field isn't the focus of the painting, but I'm trying to produce a piece that's 9000x7200 pixels, the subject being predominantly outer space-- the scaling looks awful!
What are some good resolution independent techniques to produce nice star fields?
