Just curious, and I remeber reading about this here a while ago, but
there was a good technical explanation for why, in some lunar surface
pictures, the cross-hatch patterns did not come out in the pictures.
JimO hasn't written that book yet and the sci.space.history threads that
address these things are long and make it difficult to find the
information. So, if it is not too much trouble, can someone post a link
or a brief explanation on why they are not visible?

Thanks in advance,
