Cheers Cazza, Leon, RickS & IanP,
Leon, here's a slightly desaturated version fyi.
I'd like to try this one again with either a shorter FL 'scope or a reducer. in it's entirety it reminds me of the set from that old '60's TV show, the "Time Tunnel" or "The Guardian of Forever" from Star Trek TOS.
Gotta love deep space objects, they really fuel the imagination!
