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, lift the
binoculars up to your eyes (using both hands) 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.

aDjusTing focus

Since most people have a variance of vision from their left eye to their
right eye, you must adjust the focusing system. use the following steps
to achieve focus: (1) close your right eye and look through the left side
of the binoculars with your left eye at the subject matter. Rotate the
center focusing wheel until the image appears in sharp focus; (2) close
your left eye and look through the right eyepiece (called the diopter).
Rotate the right eyepiece until the image appears in sharp focus; (3)
now look through both eyepieces with both eyes open. since you've
already adjusted the right eyepiece, use only the center focusing wheel
to refocus on a new object at a different distance.
Note: If your binocular has a diopter indicator, please note the
setting for later use for faster focus adjustment.
Hint: Eyeglasses worn for nearsightedness should be worn when
using binoculars as you may not be able to reach a sharp focus at
infinity without them.

leave the Rubber Eyecups up if you do not wear eyeglasses but fold
them down if you do wear eyeglasses to obtain the maximum field of
view. When done observing, fold the eyecups up for storage.

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
but if fingerprints (which contain mild acid) get on them, they should
be cleaned as soon as possible to avoid damaging the coatings. To
clean the optical surfaces, we recommend a lens/optics cleaning kit
available at most photo or optical shops and follow the instructions
provided closely. 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 with the naked eye.
