Having recently taken up Battlefleet Gothic again, I started knocking out celestial phenomena because I can't seem to play a game without having nice terrain. First up, some asteroids.
I bought a pack of railroad talus rock that was a dull sulpheric yellow, which I thought might be a neat change from the grey-white-beige one might typically see. I then cut up some insulation foam into asteroid shapes. I mixed up a yellow to match and painted the asteroids with the idea that I can scatter the talus around to fit the shape of the field on the table, or use a template so that we can move the asteroids around but still have a defined area.
The bases are thin circular wood disks I bought at a hobby store, and the stems are Plastruct 1/16th clear rods. I drilled a hole in the bases, painted them, and glued the rods in place with superglue. The asteroids are attached with Elmers white PVA. I glued a few pieces of the talus directly to some of the bases.
I also wanted a wrecked escort in the field. I found a simple one on Thingiverse, modified it using Meshmixer, then printed and painted it.
Quite happy with these asteroids, much better than the ones I had back in the olden days.
