Inconstant Moon is divided into three main sections: Lunar Tours - a nightly illustrated guide to what is visible on the Moon, Cyclopedia Selenica - our reference library with articles, bookstore, webguide and interactivities, and Selenographia - a zooming, panning, cross-referenced atlas of the Moon.
