By Uwe Schultheiß (Clavius Crater)
Clavius is a very nice crater on the moon surface. The smaller impacts on the crater bottom looks like the wave-circles from a stone, if you throw it flat over a lake:
Object Name: Clavius Crater
Object Type: Lunar Crater
Location: near Tauberbischofsheim Germany
Media graphite: pencil and white Paper
The telescope was a 115/805 TMB Apo refractor on Vixen SXD by 200x.
