You can try to place small spheres on your sky for the individual stars.
The best size strongly depends on the aa settings. To get single
pixel stars even with strong aa you can try to use very bright spheres.
When you use MegaPOV you can alternatively use glows - this way you
can also easily achieve a kind of halo around the stars.

try this:
sky_sphere {
pigment {
crackle form <1,1,0>
color_map {
[.4 rgb 10]
[.5 rgb 0]
}
scale .002
}
}
And if necessary, adjust the scale a bit...
cu!
