Most people can't even fathom the distance from the Earth to the Moon, which is understandable, it's "close" in our terms, but still far away by mortal standards!

I tend to steer it into a resolution question. Ideally, you have a really sweet termination line on the moon, and then I start to talk about how when you drop a pebble into water, how you see the little "blip" in the middle from the water rebounding. I tell them that rock behaves the same during impact, and you can see the frozen remnants in the moon.

The first response is always "no way!", then I let them have a peek works every time! On very nice nights, Saturn works great too!

Sorry, just noticed the last comment was nearly a month ago, sorry to bring up an old topic!

When asked something like "how far can you see with that thing?" I usually respond with something like, "Since the telescope is a light gathering tool, then if the light can reach the telescope, NO MATTER HOW FAR AWAY IT STARTED FROM, then THAT's how far we can see with it."

Oversimplified, yes. But it works.
