on this page were taken with a QHY5 (ALCCD5) camera using my 150mm
A 2x barlow lens and a right angle prism were used to increase
the effective focal length. The resulting focal length was about

The floor of the crater Clavius is still in shadow, whil it's
rim and some of the interior craters are already getting a first
glint of sunlight.
The linear feature in the center of the image above is called
the Straight Wall, Rupes Recta in latin. In reality it is a
slope, but the low angle
of sunlight creates a dramatic shadow. To the right of the Straight
Wall is the crater Birt, from which the Rima Birt is slightly
visible pointing to the lower right.
The middle crater of the trio pictured above is called Alphonsus,
if you look at this crater's rim, you will find three dark spots
on the lava filled
interior of the crater. The dark spots are volcanic ash deposits,
which are very prominent when the sun is at a higher angle,
i.e. on full moon.
This image shows the mountain range called the Apennines. The
big lava filled crater to the right of the mountains is Archimedes.
single mountain on the lava plains below Archimedes is Mons
Piton. Running through Mare Serenitatis at left is a bright
ray, that runs right over the crater Bessel.
Also take note of the dark edges of Mare Serenitatis.Near the
top of the image you can see the Hyginus Rille.
The dark, flat floored crater at right is Plato, it lies next
to the lunar Montes Alpes, which are divided by the Alpine Valley.
