These images were taken of the lunar eclipse early on the morning of
Tuesday August 28, 2007 through a Konica Minolta DImage Z2 camera at
maximum focal length of 68 mm (380 mm 35mm film equivalent). It was
mounted on a camera tripod, metered, focused and aimed manually.
Because no telescope was used, their resolution is substantially worse
the images on my moon site. The images were taken over about one hour
period. The times quoted in the images are based on camera time which
is fast by about 13 minutes.
There are two kinds of images in this set. Those that show the directly
solar illuminated portion of the moon and those that show the scattered
illumination.
The direct solar illuminated images are those that are metered to show
details of the bright
portion of the moon at a given time. This region is directly
illuminated by sunlight that traveled through space and struck the
moon. Note that throughout the imaging time, the Moon was technically
in the penumbra of the Earth. This means that the Earth was attenuating
some of the light the direct sunlight that would otherwise have struck
the moon, making it darker than a full moon otherwise would be.
However, a substantial amount of sunlight did indeed avoid the Earth
and strike the moon creating the bright portion.
The indirectly illuminated images over-expose the directly illuminated
portion in order to show the darker portions of the moon. These
portions are illuminated by sunlight that has first been scattered by
the Earth's atmosphere so they tend to have a orangish red tint (the
atmosphere bends red light less so it tends to pass through and strike
the moon).
The images shown are full resolution. In some cases, other images that
were taken at the same time may be viewed by clicking the "Alt" link.
