The Lunar 100
KEY
Lunar 100 objects that have not yet been photographed.
Lunar 100 objects that have been photographed.
Other objects that have been photographed.

The Lunar 100 list is from "Introducing the Lunar 100" by Charles A. Wood (Sky & Telescope, Sky Publishing Corp., April 2004, Vol. 107, No. 4, pp. 113-120).

I have transcribed this list for my personal use and any errors are mine. All rights remain with Sky Publishing Corp.

Unless otherwise noted, all photographs will be oriented such that lunar north is up and west to the left, i.e. the way the would appear if one were looking at the lunar surface.
