Hi Mike and List, I was so preoccupied with finding the links in my last
post I neglected to point out the omission of Jeff Hodges.

Jeff is a skilled microscopist and has one of the largest thin section
libraries (Institutional sized) in the world. His amazing images can be
viewed at
http://www.meteoritethinsectiongallery.com/index.html

In addition to being a quiet giant in the field, he has been very
generous
with me, lending me most of the material that makes up my micrograph
gallery.

In the world of meteorite thin section examination, in my opinion, Jeff
is
as good as it gets.

Hi Bob & all,
Unfortunately, Jim Tobin quit making the MBC-10
And the universal adaptors for Xpolarized lighting. Those
Who got one are most fortunate, as I treasure mine, for
Sure.
You can always get one of those $15K polarized microscopes
Or Jerry-rig a set up yourself - however, beware that
The vast majority of polarized filters for cameras are
Now CIRCULAR and cannot be used. (You must have
Two linear polarized filters - one of which can rotate for
The maximum effect.
At one time, I had a substantial array of TS s for sale,
But trash flooded the market from other sources and I
Stopped having TS s made, though I still offer some of the
Better ones as well as some of the Rarer ones left over from
the old days.
However, since Anne Black is currently the leading seller of
Meteorite thin sections in the world (she also has all of
ET's world class collection for sale) perhaps she would
Be willing to contribute information on the best, the cheapest
Set ups for viewing and for photography.
However, No one should hope to replicate cheaply the
following:

the astonishing work of Tom Phillips:

http://www.meteorite.com/meteorite-gallery/

or of John Kashuba:

http://www.meteorite-times.com/Back_Links/2010/june/Micro_Visions.htm

(both brought to us by METEORITE TIMES)

Or the work of Bob Walker's friends he generously shares
(note - Bob changes these photos from one fall/find to another
Without notice - his current selection is low in color, but past
Postings of Mossgiel, NWA 1955 & Cole Creek were all FABULOUS):

http://www.qmig.net/thin-slides.htm

Perhaps Tom or John would be willing to write an article
For us in METEORITE TIMES on how to most economically
Produce high quality Thin Section viewing and photos for ourselves???
RSVP anyone?
Warm regards, Michael Blood
