You could try Chris Colefax's Galaxy generator, though I don't remember
if it can be animated.
In general, the stars will tend to flicker if they are too small, as
rays hit a star by accident almost, and you see a sample of the much
larger number of stars truly present in the texture. Moving the camera
causes the rays to fall onto a different set of stars.
The way to do this properly (I think) is to make sure the stars are
about 1 pixel in size, which of course means scaling them differently
for different image sizes. Either that or use extreme AA settings.
BTW, you probably do have enough memory for a decent image map.
