Lunar 100

The "Lunar 100" was described by Sky & Telescope in their April 2004 article by Charles Wood. The objects are arranged in order from the easiest to the most difficult to view. The table below the map describes each object and has image links to the ones which I have observed.

Click on the image thumbnails for the full size image. Full image details will be added to the table at a later date. Many of the pictures of the higer numbered items don't show the actual item just the general area! For other "Lunar 100" sites try this list
