Schickard and Wargentin On the evening of 22 April 2005 I shot
an image of a few interesting features on the south-western limb
of the Moon. There where however two that caught my immediate
attention, Schickard and Wargentin. Where to find Schickard and
Wargentin Schickard is a large old crater with a diameter of
227kilometres. When observing Schickard through a telescope, you
will immediately notice the absence of central peaks or peak
rings. You will also see that there are some large patches of
dark and light material on the crater floor. Schickard is very
shallow compared to other craters of this size, only about 1.5
kilometres deep (Clavius is 5 kilometres deep). The original
crater floor probably has been flooded with lava which covered
the central peaks completely. After that a thin layer of bright
highland material was thrown like a blanket over the dark crater
floor (ejecta from the Orientale Basin formation). This bright
layer is still visible in the centre of Schickard. Near the
edges of the crater
