care before using them.
ADJUSTING THE INTERPUPILLARY DISTANCE (IPD)
SETTING THE DIOPTER COMPENSATION FOR A CENTER FOCUS BINOCULAR
WITH A RIGHT OPTICAL CHANNEL DIOPTER COMPENSATION DIAL
Since the distance between the eyes (specifically,
the distance between the centers of the pupils) varies
among individuals, the two eyepieces of the binoculars
must be correctly aligned (adjusted).
This is called adjusting the interpupillary distance. To
adjust this distance, using both hands, lift the binoculars
up to your eyes and look through them at an object in
the distance. Move the two halves of the binoculars
about the hinge until you see one clear circle of image
through both eyes.
Roof Binocular
As most people have a difference in visual acuity
between their right and left eyes, modern binoculars
incorporate a mechanism that allows compensation
to be adjusted between the left and right optical
channels so that each eye is presented with an image
that is accurately focused for it. This compensation
mechanism should always be set using the following
procedure whenever a new user takes up a new
binocular, and should be repeated if a different
user changes this compensation setting or if the
compensation setting is noticed by the user to
no longer be appropriate for his or her own visual
requirements.
NOTE: If you normally wear eyeglasses for normal
daily activities (not just reading glasses but “full
time” eyeglasses) it is recommended that you also
wear them while using binoculars. Simply twist the
binoculars’ eyecups down to their lowest position
to allow the proper eye relief to be achieved while
wearing the eyeglasses.
1. Pick a subject to observe approximately 50 yards or
meters in the distance.
2. Cover the right objective lens with the binocular’s
own objective cover or with your hand.
3. View the selected subject through the binocular
as you normally would but do not attempt to focus
upon it yet.
4. Keeping both eyes open, use the binoculars’ center
focus dial to bring the image seen through the
binocular into focus.
5. Without touching the center focus dial, uncover the
right objective lens of the binocular and cover the
left objective lens.
6. View the selected subject through the binocular as
you normally would once again but do not touch
binoculars’ center focus dial.
7. Keeping both eyes open, determine if the subject
is still in clear focus. If it is not, use the binoculars’
diopter compensation dial to bring the image seen
through the binocular into focus.
8. Uncover the left objective lens and view the selected
subject through the binocular as you normally would.
It should be clearly in focus to both eyes. If it is not,
repeat this process.
9. Once the diopter compensation has been
satisfactorily set for the user, the center focus dial
will change the focus appropriately for the user.

TRIPOD ADAPTABILITY
CARE AND CLEANING
PROBLEMS OR REPAIR
WARRANTY
Twist the rubber eyecups up if you do not wear
eyeglasses or twist them down if you do wear
eyeglasses to obtain the maximum field of view.
Now you are ready to use your binoculars — enjoy the
view!
If you ever notice that while using the binocular you
feel a “pulling” sensation in either eye, the diopter
compensation dial may have been moved. The above
procedure should be used to return it to the correct
balance for your eyes.
These binoculars feature a built-in tripod adapter fitting
which is a threaded screw hole underneath a cap. To
attach a binocular tripod adapter, remove the cap and
then thread the screw from the binocular tripod adapter
into the threaded screw hole. The other end of the
binoculars’ tripod adapter attaches to a photographic
tripod. Mounting binoculars this way allows for added
stability and comfort.allows for added stability and
comfort.
Binoculars do not need routine maintenance other
than making sure that the objective lenses and
eyepieces are kept clean. If repairs become necessary,
they should be serviced by the manufacturer or a
qualified binocular repair company. Collimation (optical
alignment) is the biggest concern with binoculars.
If your binoculars are roughly handled or dropped,
there is a good chance that the collimation will be out,
and they should be serviced. Dirty objectives and/
or eyepieces mean less light transmission and loss
of brightness as well as unsharp images. Keep your
optics clean! When not using your binoculars, store
them in the case provided. Avoid touching the glass
surfaces, however, if fingerprints (which contain mild
acid) do get on the glass, they should be cleaned as
soon as possible to avoid damaging the coatings.
To clean the optical surfaces, we recommend the
Celestron Lens Cleaning Kit (#93576), available at
most photo or optical shops. Follow the instructions
provided with the kit closely for best results. If you
have a lot of dust or dirt accumulated, brush it off
gently with a camel’s hair brush and/or utilize a
can of pressurized air before using the cleaning kit.
Alternately, you could use the Celestron LensPen
(#93575) made especially for cleaning binoculars.
Never attempt to clean your binoculars internally or try
to take them apart!
CAUTION!
Viewing the Sun may cause permanent eye damage. Do not view the Sun with your binoculars or even with the
naked eye.

Loosen the eyecup cuff tension knob
«IMPORTANT: always be certain the eyecup
cuff tension knob is sufficently loosened before
attempting to remove the adapter from the
binocular’s eyepiece.
Fit the eyecup cuff over the eyecup of the
binocular and tighten the eyecup cuff tension
knob until the adapter is held firmly in place
Loosen the smartphone clamp position knob (if
not already loose) and position the eyecup of
the adapter so that its aperture aligns with the
camera lens of the smartphone
Tighten the smartphone clamp position knob
and check that the position of the adapter’s
eyecup aperture stays centered over the
smartphone camera lens
Activate the smartphone camera and check
that the image seen through the binocular is
centered in the smartphone’s viewing screen. If
it is not, use the adapter’s clamp position knob
to make adjustments until it is.
NOTE: the image will be vignetted (shows as a circle
inside a black border area - this is normal. Simply use
the smartphone camera’s zoom to expand the image
until the vignetting disappears.
Pull outward on the spring clamp arms and place
the smartphone into the space between the
clamp arms so that it is securely grasped by the
tension of the arms.
