WELCOME

Thank you for purchasing Celestron COSMOS™Tree of Life binoculars. COSMOS™introduced us

to the abundant, natural beauty of the universe we live in. We hope that these binoculars help you

continue to discover your world.

There’s no better way to appreciate nature, wildlife, or landscapes than with a pair of binoculars.

We can view subtle details, like the petals of wildﬂowers, or massive geological features like the

jagged edges of a distant mountain. Binoculars also help us observe the behavior of wildlife from

a safe distance, without disturbing the animals. With your Tree of Life binoculars, you can study

birds, deer, insects, reptiles, and more. Try taking your binoculars out at night to reveal unseen

details in the night sky, craters on the Moon and the Orion Nebula.

Get ready to see a new world impossible to discern with the naked eye. Your explorations begin now!

The interpupillary distance, or the distance

between the pupils, varies from person to

person. The binocular must be correctly aligned

(adjusted) to the distance between your pupils

to achieve a single, clear image. To adjust this

distance, lift the binocular up to your eyes (using

both hands) and look through them at an object

in the distance. Move the two barrels (halves)

of the binocular closer together or further

apart until you see a single, clear image (Fig. 2).

Check that the interpupillary distance is set

correctly every time you use your binocular.

To ensure a crisp, sharp image the focusing

system of the binocular must be set to

compensate for any differences in your

eyesight. This is achieved by setting the diopter

(located on the right eyepiece) before use. To

set the binocular to your eyesight follow the

instructions below.

1. View an object in the distance through the

binocular.

2. Cover the right objective lens with your hand

or the objective lens cap.

3. Rotate the focus wheel until the image

viewed with your left eye is clear and sharp.

4. Cover the left objective lens with your hand

or objective lens cap.

5. Viewing the same object, adjust the diopter

ring until the image viewed with your right

eye is clear and sharp.

6. Your binocular is now adjusted to your eyes

and focusing on any object can now be

achieved by simply turning the focus wheel.

TIP: Eyeglasses worn for nearsightedness should be worn when using

binoculars as you may not be able to obtain focus at inﬁnity

without them.

EYECUP ADJUSTMENT

The COSMOS™Tree of Life feature twist-up

eyecups to accommodate both eyeglass and

non-eyeglass wearers. If you do not wear

eyeglasses, twist the eyecups counterclockwise

until they reach the up position. If you wear

eyeglasses, make sure that the eyecups are in

the down position to obtain the maximum ﬁeld

of view. The eyecups can be set at positions

between fully up and down which may suit

some users better.

TRIPOD ADAPTABILITY

The 42 mm version of the COSMOS™Tree

of Life binocular features built-in threads that

allow the binocular to be attached to a tripod

using a binocular tripod adapter. These threads

can be accessed by unscrewing the logo plate

found on the front of the hinge (Fig. 5).

To attach the binocular to a tripod, thread the

adapter into the binocular and attach the other

end of the adapter to a photographic tripod.

Mounting the binocular on a tripod allows for

added stability and comfort during prolonged

viewing.

WATERPROOF / FOGPROOF

The COSMOS™Tree of Life binoculars are

waterproof and ﬁlled with dry nitrogen gas to

prevent the housing from fogging internally.

CARE AND STORAGE

Your Celestron binocular will provide you years

of dependable service if it is cared for and

stored properly.

1. Protect the binocular from impact and do not

force any of the moving parts beyond their

limits.

2. Protect the optics of your binocular by

putting on all lens caps when not in use.

3. Store your binocular in a cool, dry place

whenever possible.

4. When storing for an extended period of time,

place the binocular in a plastic bag or airtight

container with a desiccant.

5. Do not leave the binocular in a car on a hot/

sunny day or near anything that generates

heat as this may cause damage.

6. Clean any dust, dirt or water that may get

on the binocular or inside moving parts as

soon as possible to prevent any unforeseen

damage.

8 IENGLISH

SERVICE AND REPAIR

If warranty problems arise or repairs are

necessary, contact the Celestron customer

service department if you live in the United

States or Canada. If you live outside of these

countries, please contact the dealer you

purchased your binocular from or the Celestron

distributor in your country. A list of our

distributors can be found on our website,

www.celestron.com

CLEANING

Proper cleaning of the lenses is essential

to maintaining the optical integrity of your

binocular. Dirty lenses diminish the amount of

light transmitted through the binocular and your

overall viewing experience.

1. Remove any dust on the lenses with a soft

lens brush or can of pressurized air.

2. Remove any ﬁngerprints, stains or smudges

from the lens surface with a soft, clean lens

cloth or lens tissue by rubbing in a circular

motion. Start in the middle of the lens and

work your way to the edges. Breathe lightly

on the lens to provide moisture if needed.

3. For a more thorough cleaning we recommend

the use of a lens/optics cleaning kit available

at most photo or optical shops. Follow the

directions supplied with the cleaning kit for

best results.
