Alex,

You are right saying that you have to have the slice in front of you.
The basic picture I just did with my camera is:
http://sv-meteorites.iol.cz/boguslavka_1.jpg
But... I posted the scanned image because it shows much more details than
you can see while looking at the slice itself. To see the details you have
to turn it here-there, left-right. You know what I mean. But the scanner
showed me a view I couldn't get with the slice in my hands.
That was the point.

Best regards,
Sergey

Thanks a bunch Andi for showing these pics, and I?m very much looking
forward to receiving your prepared slice, which will be my very own share of
Boguslavka, soon.

Hexahedrites are no easy task for a photographer or a scanner, not even if
you discuss a specimen right in front of you, "in person" so to say. I had
the great pleasure of meeting Andi a couple of weeks ago in Hamburg and
handed him my 34.8 g slice of Guadalupe y Calvo for inspection. I must admit
he was more skilled than me to point me to those tiny lines in between an
otherwise rather bare polished suface which were not due to scratches or
something evil like that, but were in fact: Neumann lines! Quite hidden in
this case, but present nonetheless! Sometimes you have to look really
closely, and sometimes a photograph or scanner pic won?t do the specimen in
front of you justice.

P.S.: sorry Sergey, I had simply overlooked your scale figures at the bottom
and left side of your beautiful pic! Nonetheless, some "material scale", a
scale cube or a scale stripe or even a pencil or knife or something like
this will usually work better with ones "imagination" than just a figure...
:-)

Best,
Alex
