Lunar 100 Project

The Lunar 100 catalog was first described by Charles A. Wood on November 27, 2012 and was published in the April 2004 issue of S&T. Objects in the Lunar 100 are arranged from the easiest to view to the most difficult.

When I first heard about this project, I immediately scanned all my previous lunar images for the objects in the Lunar 100 catalog. In the meantime I try to photograph sporadically still missing objects, in order to have sometime all 100 objects together.

Below you can see the current status of my project.
