STELLARVUEF80 13X80 FINDER
All Stellarvue F80 series finderscopes are made to
provide the highest level of performance. We start
with an astronomical quality objective (most finders
use binocular objectives), which provides a sharp,
high contrast image. The finder features fully multi-
coated optics, a 2” helical focuser with rubber grip
and 1.25” adapter, and a high quality, 50 degree, fully
multi-coated eyepiece with a large eye lens and a
glass crosshair reticle. This finder may be used with either our standard or
our illuminated reticle eyepiece.
FOCUSADJUSTMENT
Unlike many finders that use inexpensive slide tube focusers or require
screwing and unscrewing the objective to reach focus, the Stellarvue can be
focused to accommodate different people thanks to its helical focuser.
erely turn the rubber grip to attain focus. The finder will accommodate var-
ious standard 2” or 1 1/4” eyepieces(with adapter). Use wide field premium
eyepieces for the sharpest possible field.
The supplied eyepiece is designed to provide a wide
field of view. Eyeglass wearers may fold back the rub-
ber eyecup to get in closer and enjoy the entire field.
First, focus the reticle by turning the knurled top of
the eyepiece.
You may then focus the finder using the image
focuser below it.
2” Eyepie es with Reti le (Sold Separately)
The F60 may be used with our 2” reticle eye-
pieces. We offer our E7026R 26mm with 8.65x
magnification or our E7032R 32mm with 7x mag-
nification. Both will give you a “porthole view” and
will also be able to work with an EI2 illuminator.
RETICLE ILLUMINATOR (Sold Separately)
Battery replacement: As
shown, the illuminator is a
tubular electronic device that
attaches to a special base on
the illuminated eyepiece. It is
powered by two standard
GPA76 batteries. To replace
the batteries, unscrew the end
of the illuminator as shown to
the right. When installing
new batteries, be careful of
battery polarity. Inserting a
battery with the polarity reversed will damage the circuit and void the
warranty.
ON/OFF BRIGHTNESS: Rotate the on/off brightness knob clockwise to turn
on the illuminator. Turning the knob clockwise increases brightness. Turning
it counter clockwise decreases the brightness until it clicks off.
F80 RINGSYSTEMS (Sold Separately)
The F80 uses the R80 ring systems. These come with various bases that
permit attachment to a number of different telescopes.
R80AT: Low profile universal base. ounts to Stellarvue and Televue
clamshells. ay also be screwed to any flat surface or tube.
R80DA: ounts to many dovetail shoes on the market including Stellarvue,
