The Lunar 100

The Lunar 100 is a collection of some of the Moon's best known objects observed by members of the Hampshire Astronomical Group, either drawn, photographed of captured by CCD. This simple moon always keeps revealing new views and new mysteries while still remaining our nearest neighbour in Space. For full details of the Lunar 100, please read the excellent information provided on Sky and Telescope Magazine's website pages.
