The Hitchhiker's Guide to the MoonA guide to telescopic observations of the moon
by Akkana Peck, with help from many contributors
The diagram at right represents the moon as it appears on the date shown, with light grey showing the areas which are in sunlight, black showing the areas not lit. Usually, you'll see the most detail at the terminator, the dividing line between light and dark.
The numbers correspond to chart numbers in Antonin Rukl's Atlas of the Moon.
The Roman numerals around the edges represent the libration zones, areas of the moon's far side which are sometimes visible edge-on to observers on earth.
On the libration charts, purple indicates a favorable libration; blue indicates a very favorable libration. In most cases the terminator has to be nearby in order to see much detail in a libration zone.
