The Lunar 100 is a list of interesting lunar features compiled by Charles A.Wood, they are sorted in ascendign difficulty..
When an image is available, the name of the feature is a link to this image/page.

For a complete list, with coordinates and Rükl chart numbers, see the Lunar 100 list on the web site of Sky & Telescope. A laminated card of the Lunar 100 is also available. I came across another website with a Lunar 100 project by Doug Anderson, the person behinde shoestring astronomy: http://www.shoestringastronomy.com/lunar/lunar100.htm
