I'm limited by the magnifications
available. There is no zooming facility
in a compound microscope. A lower power
objective doesn't show enough detail.
The one used for this picture was a
10/0.25 Leica Fluotar. The image is
salicylic acid (salicylate) crystallized
from 70% ethanol directly on the slide
under a cover slip. The picture was
taken using polarized light, a Lomo
aplanatic condenser and a Zeiss (Rot)
full wave retardation plate. The
crystals formed very slowly and that why
they are so good looking. Final
magnification is about 100X but I
haven't checked this yet. The CCD
doesn't fit the graticule in the
binocular eyepiece (made for 35mm and 4
x 5) so I have to do some arithmetic.
These pictures (a selection) will be
printed -- big -- framed and offered for
sale in the US very shortly. Some will
only be printed once -- making them
originals.

Don,
Cyber paleontology? Can even imagine fossil impressions.
IOW, very interesting. I was, however waiting to see all of the
rectangular "slab".
How (why) did you do this? =)

been taking a few fun shots. All start
as big TIFF files but I've converted one
to a small jpg and here it is:
