yup..there was a background of the ground in that episode. I don't remember the name of it (more than 800 episodes of Star Trek out there, y'know...;), but you could see what looked like farmland, and some low-lying clouds. Roland Green has an obsessively-cataloged web site with synopses of every Star Trek episode (also Blakes' 7, and all 40 years of Dr. Who, etc...and they think I'm nuts...;)

Long story short; if you have the episode name, there's other Star Trek sites that have screen caps of every episode. Might find some reference material there.

I wish I'd said that.. The Staircase Wit
