Thank you for purchasing Celestron binoculars and we hope you will

have many years of pleasure with them. To maximize your enjoyment of

the binoculars, please read these instructions on use and care before

using them.

aDjusTing ThE inTERPuPillaRy DisTancE (iPD)

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.

caRE anD clEaning

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.
