Observing the Moon for beginners

Beginning backyard-astronomers often ask me “what do I need to start observing the Moon”. Basically you only need two things to start off with lunar observing: a small telescope (or binoculars) and a map of the Moon. You also should know a few other things: when to observe the Moon and what to observe (as a beginner). In this article I will try to answer these questions. In the near future I will write an article for those wo are past the beginning stage, the "intermediate" observer. This article however, is meant for the beginning lunar observer.

Lunar phases

Why do you see different portions of the Moon lit by the sun

The Moon has no light source of its own. It "shines" because it reflects sunlight. At any given moment, half of the surface is lit while the other half is dark. On the Moon there is night an day, just as on Earth. But what causes the changing appearance of the Moon, what causes the lunar phases?
