That's quite a nice photo. Can you provide any more exact information
as to when it was taken (what hour) and from where on Earth (city or
approximate lon/lat)?
As Kurt says, it gives a nice view of Faustini, but only a small part
of it. The attachment labels some of the more prominent landmarks.
The large crater Amundsen is the most obvious one close to the limb.
On its limbward side one can see a part of the sunlit interior of
Idel'son L, and on the Earthward side the long, highly foreshortened
shape of Nobile.
Extending down to the right from the right-hand arrow pointing to
Idel'son L there is a bright band of light. That is part of the inner
walls of Amundsen. To the right of that, just above the right-hand
arrow pointing to Nobile is the left-hand part of a dark elliptical
shadow. That little partial ellipse of black just above the arrowhead
is the interior of Faustini. Most of it is cut off by the edge of the
frame. If it were not for the edge of the frame, Faustini would
extend to the right to about the "N" in "Nobile".
The elevated landmass below Nobile is the one Kurt is referring to as
"Leibnitz Beta". It also extends beyond the edge of the frame.

Nice work, Rainer! Thanks for the detailed image data and the
observing location.
Do you have the time for the eariler image?
As Clif says, this image shows the remainder of Faustini. In the
attachment I have drawn arrows to the rim points that define the
limits of Faustini's shadowed bowl, and also those of Shackleton and
Shoemaker. In each case, a bit of sunlit inner wall can be seen at
the right-hand end. For Shoemaker, the Earthward rim cannot be seen
at this sun angle, causing the to crater merge into a larger shadowed
gulf. The crater bowl of Shoemaker is actually a highly flattened
ellipse just like the others.
In the attachment, I have also pointed out Malapert E, a distinctive
feature on the flanks of Leibnitz Beta. With this lighting it is
usually easy to spot, both in photos and visually. The streak of
light reaching out from it towards the Shoemaker label helps to
confirm you have the right crater. Faustini can then be found between
Malapert E and the limb, although a very strong libration in longitude
has here placed it a bit more to the right than usual. The presence
of Shackleton, nearby, with its distinctive cone-shaped outer walls is
another confirmation.

That's partially my fault, I think. Images have been posted in a
variety of orientations, but in the ones I've labeled (such as the
present attachment), I've usually rotated them so the limb is at the
top. My mind is not very flexible, and I find it hard to recognize
features when mountains go down and valleys stick up. Many other
people are apparently perfectly comfortable with either orientation.
I'm not.
And yes, despite the strong focus on Faustini here so far, if LCROSS
launches on the current schedule, it looks like the impact will most
likely be in a crater near the north pole. See Kurt's "Finders" page
for a list of possible locations:
