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
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
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!
