I found myself drawn to Stiborius tonight, as it was just coming into
its own in the light, and had a very interesting interior structure,
with mountains that seemed to almost form a chevron or "sergeant's
strips." About half the interior is smooth and half structured, creating
an interesting aesthetic.
At sunset, Stiborius has an interesting ring of shadow around it,
and a lovely sunset ray streams into the crater from a smaller crater
just outside the outer ring of shadow.
