Does anyone have a digitized copy of the Micromega/Peak Model 1 grain focuser? If you could email me it, I'd be very grateful!
Thanks!

Let me check in the transporter room...
If you mean the operating instructions, there are no pictures so the entire instructions may be digitized in ascii...
MICROMEGA CRITICAL ENLARGING FOCUSER
Catalog Number 468-006
OPERATING INSTRUCTIONS
The unusual configuration of the
focuser, the pivoted eyepiece and the
length of the mirror (86mm) make the
Micromega accurate and effective even
when used off center of the projected
image. While conventional grain focus-
ers must be used directly under the lens,
the Micromega can examine and focus
any part of the image area up to 30
degrees from the optical axis of the
enlarger lens, an exclusive feature. The
white cavity with center hole is designed
to permit the user to place a coin on the spot
of the easel on which he wants to focus
and then position the Micromega
precisely by placing it over the coin.
When positioned on-easel, with a nega-
tive in place and the enlarger on, the
Micromega reflects the projected image
to the eyepiece where it is magnified 10X.
The rectangular reticle at the focal point
delineates the "target area" and the en-
larger is focused until the grain structure
of the negative is sharp.
FOCUSING
Set up the enlarger for printing; size and
compose the print; throw the enlarger
into approximate focus, and with the
mirror cover open, place the Micromega
on the easel. For highest accuracy, keep
a scrap of enlarging paper under the
Micromega to position the base of the
instrument at the exact paper plane.
Since the Micromega need not be used
directly under the enlarging lens, it can
be positioned to focus the most import-
ant part of the projected negative.
Look through the eyepiece and swing it
on the pivot until the full field can be
seen brightly. Finally focus the enlarger
until the granular structure of the
negative appearing within the double
framed rectangle is sharp. Remove the
Micromega and print.
CARE OF THE MICROMEGA
Treat the Micromega like the fine instru-
ment it is. Don't knock it about and don't
touch the mirror with anything but a fine
camel hair brush or compressed air.
Keep the cover down when not using the
focuser. Clean the eyepiece lenses with
lens tissue or compressed air if needed.

Before Using:
The Micromega is provided
with a built-in blue filter that can be swung
into the light path at the top of the eyepiece. It
is used for black and white enlarging only to
improve contrast and optimize focusing
accuracy.
The first time the Micromega is used, the eye-
piece must be adjusted to the vision of the
individual user. With the mirror cover open, in
normal light or under the enlarger, rotate the
knurled eyepiece until the double framed
reticle is sharp. Although this need only be
done once, check this setting each time you
use the focuser as a matter of good operating
procedure.
