I've also been asked the "how far can you see?", and also "how much power does it have?" So I say right around 8000x, and always get a "hmmm" accompanied with a knowing 'nod' or "that's about what I would have guessed".

One thing that happens no matter what the age of the viewer is after looking through the eyepiece, they ALWAYS step back and look to the sky in that same direction, as if they were going to see the object naked eye, too.

Re the astrology confusion...more than once, when my astronomy hobby is mentioned, I've been told that "I don't really believe in that stuff, but it's fun to read my horoscope anyway."
