I had a lovely, understated and unexpected experience at Astrofest at the start of this month with the sky tour I conducted.
After rabbiting on first about the naked eye stuff, the first telescopic object was Omega Centauri and the usual blab about it. The next object, it occurred to me NOT to tell the attendees what it was they were to see next. Instead I told them they would have to "discover" what it was for themselves!

Not only was everyone thrilled to pieces with their discovery, but they also didn't spill the beans about what it was that they just saw. Instead, all the waiting crowd had to go by was "WOW!", "OH MY GOD!", "NO WAY!", "THAT'S AMAZING! ", "I CAN'T BELIEVE IT!" It was just a lovely thing that everyone just joined in on allowing the next person to have the same thrill of discovery for themselves
What was it that they "discovered"? Well, you are just going to have to wait your turn at the eyepiece...
