I have 2nd edition books available at
present. They are available for $25,
with free shipping, the same as the
1st editions. The second edition is
new and improved and has thicker
paper, multiple revisions and new
additions.
I am presently working on a
follow-up project on
high-magnification imaging, but that
project is only partially finished at
present and will be awhile until it
sees the light of day.
Mark.
