BINOCULARS

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.

1. 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.

2. 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.

For Zoom Binocular models – to increase or decrease power, move

the zoom lever. To adjust focus you ﬁrst zoom the binoculars to

the highest power and then adjust the focusing system as above.

Then, when zooming in and out your binoculars will be in focus.

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.

3. Set the Rubber Eyecups 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.

4. Tripod Adaptability Porro Prism binoculars feature a

built-in tripod adapter ﬁtting. On these models, a threaded screw

hole is 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 binocular tripod adapter attaches to a photographic tripod.

Mounting binoculars this way allows for added stability and

comfort especially when viewing at high powers.

5. 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!

6. Caution! Viewing the sun may cause permanent eye damage.

Do not view the sun with your binoculars or with the naked eye.

7. Problems or Repair If warranty problems arise or repairs are
