Half Moon in Tucson
8.03.2004 | Lunnoe foto dnya
Lunar globes are rare and wonderful. At one time I had the small metal Replogle globe and I still possess a tiny NASA one plus my joy - a 12" Soviet-era globe that has unfortunately suffered plate tectonic ruptures from too many moves.
Sunset over Clavius

In 1858 Julius Schmidt became the director of the Athens Observatory, and he is best known for the large (2 meter diameter) moon map that he published in 1878. However, one of his finest lunar images appeared in his small book, Der Mond, published 22 years earlier (Leipzig, 1856).
Color Moon Map

The Jan 28 LPOD astonished many observers with its detailed color rendition of the Full Moon. Now that imager, Filipe Alves, has used advanced computer manipulation to create a Mercator-like projection color image of the Moon - the first I know of. This is a level of sophistication that is new to amateur Moon mapping.
Goodacre's Imbrium

Goodacre's red volume The Moon is my favorite observer's guide to the Moon. The main reason is the 25 maps and assorted charts which are clear and uncluttered. Elger's 1895 The Moon also had wonderfully clear maps, but his Moon was shown in just four quadrant maps so little detail was depicted.
What's All The Excitement About Mars?

During the last year, bright Mars has performed numerous pirouettes with our Moon - approaching and even passing behind it at times. And well Mars should seek to hide, for the massive hype last summer...
Ptolemaeus Peak Heights
3.03.2004 | Lunnoe foto dnya
Lunar observers, long impressed by lengthy shadows of peaks, have often speculated on the their heights. Galileo used shadow lengths to estimate peaks heights, and Schroter, Madler and especially Schmidt determined a few thousand peak heights and crater depths this way. Shadow measurements at the telescope require great care, and are susceptible to systematic error.
Ptolemaic Sunset

Ptolemy, the Greek astronomer, dominated medieval science, and his crater dominates the central region of the Earth-facing hemisphere of the Moon. Ptolemaeus, the Latinized version of the Greek name, is 153 km wide and 2.6 km deep. The rim is battered and a piece is missing on the west side.
The Arrowhead

Lunar scientists don't always focus on the same objects as amateur observers. The latter group usually observes and images the same few dozen prominent features. The former group looks for anomalies that hint at unusual rock compositions or formation mechanisms.
New Moon's Arms

We say that the old Moon is in the new Moon's arms when its only a few days old and light bounced off the Earth faintly illuminates the portion of the Moon not directly lit by the Sun.
