M51 Dust Noise

In order to capture a little bit of the variety seen in the dust edge on, I've added a noise based cull and shift to the dust particles.  A larger sized noise cuts into the particle set based on the distance from the center creating a more varied edge.  The second noise will shift the positions of the particles in the Y axis to create even more variety.  Below is a close up of the dust- I'm not sure we'll be able to get that detailed, but we can get closer using noise methods.

Clip of the noise with the large scale noise applied. (Stars are black and used to create a mask so we can see the noise correctly.)
