This is a Tutorial to make some Nebulae using my Star Field Tutorial
Set your Foreground Colour to a Sky Blue style one.
Now after you have made the Star Fields make a New Layer and call it Nebula.
Now with your Sky Blue go Filter>Render>Clouds.
Then go Filter>Render>Difference Clouds.
Keep Rendering your Difference Clouds until you make a decent enough Nebula looking effect
Now change you Blending Mode to Screen.
