Star Trek has an embarrassment of riches; for example, the awesome spaceship designs did not stop at the U.S.S. Enterprise and the Klingon Battlecruiser. The Romulan "Bird of Prey" is another smasher of a craft.
Seen below is the miniature built by Wah Chang and Film Effects of Hollywood for the episode "Balance of Terror". This 35mm motion picture clip is from the optical house. They started the starfield in at the beginning, over the slate. (It may be a composite test; which would include exposure and density levels.) The black background is actually the bluescreen at Film Effects.
