 Isn't full moon the best time to see the moon through the telescope? Well, let's do an experiment and you tell me. The moon's surface has a lot of what? Craters. Right. You want to see craters when you look through the telescope? Yeah. This represents a small area of the surface of the moon. Here's a ball representing the whole moon. This pan represents the area inside the square drawn on the little moon. Would you like to hold the moon? Sure. Let's use this as the sun. Will you hold the sun where it will be when the moon is full straight over the moon? Noon on the moon, if you like. What kind of detail can we see? Not that much. It's a little flat. Okay. Well, let's make it so that we have a quarter moon. Would you like to hold the sun here? Okay. Now, how much more detail can we see? Quite a bit more. So, is full moon the best time to see detail? No. It's better than when we can see the shadows. Ready to look at the moon through the telescope? Yeah.
