First make a new document any size, and than go grab a planet render (Moon, earth, mars, jupiter, manmade etc etc), heres the one I'll be using. MAKE SURE YOU SAVE! IF YOU DON'T IT WON'T HAVE TRANSPARENCY! I won't be using the whole thing only part of it. make a new layer and fill it with black. go to filter>noise>add noise use the following settings. Amount>15% Distribution>Gaussian Monochromatic>Checked Put the planet layer on top of the star layer. There ya go, quick and easy stars, if you want you can add a little lens flare for that extra effect, heres my result. Thanks for taking your time to read Dudesareus!
