Texture And Stars [GIF]

So I'm pretty happy with a technique I've been using for a while to generate noise, textures and (recent discovery) stars. Neat huh?

1. Create a new layer
2. Fill it with black
3. Filter -> Add noise -> Gaussian, 25%
4. Hue/Saturation -> bring saturation right down
5. Set the blend mode of the layer to "screen"
6. Set the brightness down, and the contrast right up
7. Keep bumping the contrast and play with the brightness till you get the result you like!

That's it. The spacey one actually has the blend mode set to 'color dodge'. Enjoy!
