First, I made the backdrop. I took a single plane and put my favorite starfield (available in the freebie section at Renderosity) into the glow channel and rotated it into the orientation for the poster. I could have put it into the backdrop and rotated it there but I chose the plane method instead. Then I added a sphere and textured it with functions from EnhanceC Space 3D. The rings are also made using Enhance C Space 3D functions. I added my standard planetary atmoshperic haze thingamathinga (available in the freebie section at Renderosity) and rendered the backdrop. There is one distant light and no HDRI lighting (or ambient light).
