The Association of Lunar and Planetary Observers Lunar Section focuses on the topography of our nearest neighbor in space. It maintains a gallery that contains thousands of images and drawings of the Moon based on the Rükl Atlas of the Moon as well as offering multiple programs that the amateur astronomer can contribute to. The section has a monthly newsletter entitled The Lunar Observer that features lunar articles, drawings, and images from similar-minded lunar amateur astronomers across the globe. Contributors use telescopes of all sizes, from 60 mm to over 1 meter - but most observations are done with small, modest telescopes. We welcome you joining our ranks and contributing to the ALPO Lunar Section to enhance your observing skills and learn from other more experienced observers.
