**Firstly i'd just like to appologise not only to adien but everyone else for not being active. I hardly have time for my own account and work/school/being social is a bitch to keep up with art.....**

This tutorial explains how to make a sun for space scenes, I think you figured that out I worked on this in three days about some 5 hours work (I took my time). I used this technique (with some other effect on it) on my latest scene called: "Transmission failed". So you can use this for whatever you want, but I think that it's best for a sun though. The picture I made in this tutorial has to bright colours though to be a sun, but they only are needed to give you an idea not to show the best you can make of it

Have fun!

Edit: I forgot to tell you guys that with the brush making you should change the texture mode to multiple so I edited the picture to it and it should work now
