They talk about the moon appearing larger near the horizon, but they say astronomers and psychologists don't agree on how to explain it. First of all, if a camera is capable of recording the difference, what do psychologists have to do with it? And second, isn't it just refraction through the atmosphere? Light's coming in at a steeper angle and passing through more of the atmosphere than it is when the moon is higher in the sky. I've never heard any other theory.
