Mare Imbrium
The Mountains and the Sea
The area changes dramically as the sun continues to rise, as seen in this Plato image taken during a prior session.

An image of the
southern portion of the 8-day terminator was taken at the same time.

This image is from a single one-second ISO 100, 48-bit image that was taken on 09-Feb-2003 with an 8" Mak-Newt and Canon D60 digital SLR through a stacked pair of TeleVue Powermates (2x and 4x).

Processing done in
Images Plus and  final polish with Adobe PhotoShop.
Sunrise sweeps over the largest of the moon's lava flows, "The Sea of Showers" (Mare Imbrium) in this image of an 8-day moon.

A hint of the eastern rim of crater Plato is seen in the upper left as it is caught in a glint of sunlight. The Alpes range to the east and wrinkle ridges running along the terminator are stunningly highlighted by long shadows and high contrast as they too are awakened by the morning sun.
Vallis Alpes cuts through the range, its western wall bathed in light and just the barest of hints can be seen of the fault that runs along its floor. As the angle of sunlight increases slightly, good "seeing" conditions will reveal the fault more fully.

Aristoteles lies in the northeast (upper right), it's western wall already washed out, but much detail present in the terraces on the opposite side.
The Apeninus range completes the arc around Mare Imbrium, with Rimae Bradley and Archimedes carving paths through the dark basaltic floor, stretching to meet crater Archimedes.

Many features are seen in greatest detail as the terminator sweeps past, accentuating the contours with the long shadows that are cast, and are a favorite haunt of mine!
