ASE Lunar 100 Project

This is our attempt to image as many of the Lunar 100 objects as we can. It is a list of one hundred of the most interesting features to observe on the Moon. The list was first described by Charles A. Wood in the article The Lunar 100 in Sky & Telescope magazine, April 2004. They are arranged in ascending order of observational difficulty. We start populating it March 2021. 97/100
