This is an action made from Qzma's Sun tutorial, over at [link] - Check it out, it's very helpful, and there are some mightily fine tutorials there too.

This will produce a very sexy sun for any space-art you may be doing.

Start with a black background with a circular selection active, then run the action. Then repeat it until you have the kind of intensity you wanted from your sun. Then merge the layers down and you're laughing.

MAC: If you place this into Applications > Adobe Photoshop > Presets > Photoshop Actions It will appear in your actions palette (next to your history palette in default workspace)

Otherwise, on either windows or mac, you can locate the action and run it from whichever folder you downloaded it to (so don't forget where you put it!)

A big thanks to Qzma for letting me submit this. I hope this is helpful. If you download it, let me know how it goes and whether it's any good!

Enjoy
