Never attempted to make a raw galaxy picture in bryce myself. Have attempted to make nebula's but they were never up to snuff either. Id recommend you check out this 2 programs and make the galaxy-starfeild outside. Then just import them into bryce as a distant picture, or as a space scene with no atmosphere etc. http://www.astroscape.com/ The above is shareware, therefore no nags etc. Also take a little longer to learn. http://www.diardsoftware.com/ This one is a time limited demo, but you can have a galaxy out in no time.
