Quoting El Barto !
So, uh, like, how did you do that?
It is actually 4 renders, and a background. The background (the spacedock interior) was taken from Celestia. POVRay reacted very badly to the amount of pieces in the Enterprise and Excelsior, so I needed to render both models separately. Since the models don't interact (cast lights or shadows on each other), this is okay. The shuttlecraft are not to scale, so I had to render them with the camera further away to make them appear "right".
