NATURE SERIES 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: 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 Twist Up Rubber Eyecups

Twist 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.

Now you are ready to use your binoculars --- enjoy the view!

4. Tripod Adaptability

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 binocular tripod adapter attaches to a photographic tripod.

Mounting binoculars this way allows for added stability and comfort.

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 even with the naked eye.

7. Problems or Repair

If warranty problems arise or repairs are necessary, contact the Celestron customer service 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).

8. Warranty

Your binocular has the Celestron Limited Lifetime Warranty for U.S.A. and Canadian customers. For complete details of eligibility and for warranty information on customers
