BINOCULAR

Thank you for purchasing this Celestron Royal Observatory

Greenwich binocular. We hope you will have many years of

enjoyment with it. To maximize your enjoyment of this binocular,

please read these instructions before using it.

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 the Diopter 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.

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. 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. 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. 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. 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

necessary, contact the Celestron technical support department

if you live in the U.S.A. or Canada. If you live elsewhere, please

contact the Celestron dealer you purchased the binoculars

from or the Celestron distributor in your country (listings on the

Celestron website).
