Marco,
I really like the main image with no embossing.  Very nice.

brighter areas are "higher" than darker areas.  This is true with uniform
surfaces (i.e., one color), but definitely not true with the Moon.  There
are many impact craters in the maria that are brighter than the surrounding
lava (because brighter, underlying material is exposed), but the embossing
effect makes them appear like little bumps instead of depressions.
