ENCOUNTER - BREATHTAKING VIEWS
OF THE NIGHT SKY AND THE WORLD
AROUND YOU.
The large optical system of the BARSKA
Encounter Binocular Telescope provides the
amount of light gathering that is necesssary
for astronomical observation and , unlike a
conventional telescope, allows you to use
both eyes simultaneously for viewing. As a
result, you have better image resolution,
contrast and brightness than a similar size
telescope. The included eyepieces provide
20x magnification. Optional interchangeable
eyepieces (available from a camera or
telescope dealer) let you vary the
magnification for different types of
observing. The 90-degree eyepiece viewing
angle makes observing at night more
comfortable and convenient. With proper
care, the rugged body construction and
waterproof design of this instrument will
ensure years of enjoyable viewing.
Important: Please read the following
instructions carefully.
2. INSERTING THE EYEPIECES
One of the most important features of the
Encounter Binocular Telescope is its ability to
change eyepieces.
To install the included eyepieces:
1. Remove the cover caps from the
binoculars and eyepieces.
2. Insert the eyepieces into the binocular's
eyepiece holders.
3. Gently push the eyepieces
down into the holders until
they are fully seated (Fig.2).
4. To remove the eyepieces,
carefully pull the eyepieces
from the holders.
3. EXTENDING THE LENS SHADES
The extendable lens shades help to increase
contrast by preventing unwanted glare from
entering the objective lenses. They also slow
the formation of dew or moisture on the
objective lens exterior surface.
To extend the lens shades:
1. Grasp lens shade with
your fingers.
2. Carefully pull lens shade
outwards (Fig.3).
4. ADJUSTING THE EYEPIECE
DISTANCE BETWEEN YOUR
EYES (INTERPUPILLARY DISTANCE)
To adjust the interpupillary (IP) distance:
1. Turn the chrome IP knob located between
the eyepieces.
2. Rotate the knob until the distance between
the eyepieces matches the distance
between your eyes.
3. When properly
adjusted, you should
see a single round
field of view when
looking through
the eyepieces.
4. Important: Make this adjustment
BEFORE you attempt to focus the
binoculars.
1. USING A TRIPOD
When observing with a large aperture
binocular like the Encounter, a sturdy photo
tripod such as the
BARSKA AF10738 or
an altazimuth mount
is required. To attach
the Encounter to a
photo tripod, simply
thread the tripod's
1/4"-20 mounting
stud into the threaded
hole in the Encounter's
mounting plate.
To attach the binocular
to an altazimuth mount,
that utilizes a dovetail holder, an optional
dovetail L-Bracket (available from a camera
or telescope dealer) is required. The
L-Bracket connects to the Encounter's
mounting plate and has a dovetail bar that
goes directly into the mount's dovetail
holder.
