->Hellstryker: Innocent until proven guilty I say...

Though that is kinda suspicious, I'm gonna ignore it for now and concentrate on sharing the knowledge.
Basic starfields aren't difficult to make... nebulas and details like milky way (denser but weaker stars basically) take some time to get looking real...
Grayscale noise level 0.20 -> Brightness/Contrast ~ 60/110 creates a pretty good, very basic starfield. However it's important to have your monitor correctly calibrated because otherwise there's going to be contrast/brightness issues and people are going to say that there's too many or too little stars and yadda yadda. The contrast and brightness can be adjusted to change the density of the starfield and the strength of it.
Then you can do things to it with layer modes and gaussian blur [values 1.5 - 2 gaussian blur tend to look good IMO] and colouration to put in some weakly red, blue, yellow and orange hue to the brightest stars.
This is a good sample of this technique, however it is optimized for use as FS2 skybox background, not an art background especially. Click to enlarge to epic proportions (2048^2).
