Question...

I've looked through the memories, but have not found what I'm looking for... although it is possible that I simply missed it...

is there a tutorial that will show me how to make this picture of the Northern Lights shimmer.

or can someone tell me how to do it?

I am attempting to make it into an icon... but would like it to shimmer as if one was actually looking up at the Nothern Lights.

I use PS7 & IR.

Any help is greatly appreciated.
