The earliest drawings of the Moon were of the entire body. By 1665 Robert Hooke, the English rival of Isaac Newton, published (in his Micrographia) the first drawing of a single feature, and it was remarkably accurate.
Lake of Death

Do you consider Lacus Mortis - The Lake of Death - a crater? Because of the mare-like term "lacus" some observers just see it as a patch of mare material linking Mare Frigoris and Lacus Somniorum.
Nodding Moon

We glance up and notice the Moon, seeing that its phase and place in the sky are different from yesterday, and we congratulate ourself for our visual astuteness and for being in tune with the cosmos. But is that the only way the Moon changes?
Outrageous Lunar Colors

All observers know the Moon is almost entirely a monochrome world with only subtle hints of color. And we have all seen the colorful lunar images composited from spacecraft data acquired through red, blue and green filters.

Is there any volcanism on the Moon? For the first half of the 20th century this had been a burning question. Finally, the 1949 publication of Baldwin's book convinced most scientists that lunar craters had formed by high speed impacts.

Impact basins are characterized by a family of features such as multiple rims, concentric fractures and ridges, a central depression, radial markings, and extensive ejecta deposits. This list results not from a single perfect basin, but from recognizing consistent patterns in all the Moon's basins.

Anyone who read Sky & Telescope during the late 1950s and early 1960s was treated to wonderful drawings of the Moon by artist and observer Alika Herring. Of Hawaiian origin, Alika was also a famous Hawaiian steel guitar player and a master mirror maker at Cave Optical Company.
Platonic Nirvana
24.01.2004 | Лунное фото дня
The Holy Grail of competition for visual observers and imagers is the floor of the crater Plato. With a good 5" telescope, three and sometimes four craterlets can be seen. The very best amateur images, until now, show a dozen or so crater pits.
Infant Moon

Look west tonight, when the twilight glow is lingering, for the slender crescent of the 2-day old Moon. This is always a wonderful and frustrating time to observe. Against a pinkish-blue sky, the Moon...
Ring Around the Moon

Some people think they are rare, but a ring around the Moon - a Moon halo - is not especially. However, they are beautiful and uncommon enough that its fun to get other folks to come out of the house to see them.
