Alright this is what I have so far today. I wanted to get the base asteroid done today but, well it didn't happen. I did get some of the mounts mocked up. It was a tremendous pain in the rump but, its looking cool. Not nearly done yet, but its getting there.
I'll add some small asteroids here and there, I've been using 1/8" acrylic rods to support them, its thin enough not to notice it right off, but just strong enough to support weight. I still need to adjust the supports to make them look neat, they're not invisible.
