Dust + Stars w/ Screen Mode

Combined the dust and stars together to play with exposure levels.  With the screen mode, the stars seem to start washing out in terms of saturation- hopefully this can be fixed in post.  With the addition of the dust, the stars exposure level could be picked up a bit.  Its going to be tricky balancing the 2 so as not to get a dirty looking or overly bright galaxy.
