This Atlas is based on high-resolution electronic images of the terminator area of the Moon under 47 different illuminations. Each image is displayed across two or three pages. Features as small as 1-2 kilometers can be seen. For each illumination, accompanying text describes the major features shown in each view, along with larger-scale images of selected areas, which are indexed with their positions and dimensions.
Two text chapters describe and illustrate the techniques of lunar observing and the types of landforms. Observing data are presented through 2010. Experienced observers will find the Atlas an invaluable planning tool, while beginners will gain an understanding of lunar geography and geology. There is an index of 1000 named lunar formations, cross-referenced to the images.
No other atlas shows the Moon under such a variety of observing conditions.
