CELESTRON Nature DX ED Binoculars 12×50
CELESTRON® NATURE DX BINOCULARS
Thank you for purchasing a Celestron Nature DX binocular. We trust this binocular will provide you with years of enjoyment and faithful service. Please read the instructions carefully before using your binocular to ensure proper use and care.
WARNING: Viewing the Sun may cause permanent eye damage. Do not view the Sun with your binoculars or even with the naked eye.
ADJUSTING THE INTERPUPILLARY DISTANCE (IPD)
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.
SETTING THE DIOPTER / FOCUSING
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.
- View an object in the distance through the binocular.
- Cover the right objective lens with your hand or the objective lens cap.
- Rotate the focus wheel until the image viewed with your left eye is clear and sharp.
- Cover the left objective lens with your hand or objective lens cap.
- Viewing the same object, adjust the diopter ring until the image viewed with your right eye is clear and sharp.
- 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 Nature DX binoculars 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 that may suit some users better.
TRIPOD ADAPTABILITY
Mounting the binocular on a tripod allows for added stability and comfort
during prolonged viewing. Nature DX binoculars feature 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).
WATERPROOF / FOGPROOF
The Nature DX series binoculars are waterproof and filled with dry nitrogen
gas to prevent the housing from fogging internally.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. 
CARE AND STORAGE
Your Celestron binocular will provide you years of dependable service if it is cared for and stored properly.
- Protect the binocular from impact and do not force any of the moving parts beyond their limits.
- Protect the optics of your binocular by putting on all lens caps when not in use.
- Store your binocular in a cool, dry place whenever possible.
- When storing for an extended period of time, place the binocular in a plastic bag or airtight container with a desiccant.
- Do not leave the binocular in a car on a hot/sunny day or near anything that generates heat as this may cause damage.
- 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.
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.
- Remove any dust on the lenses with a soft lens brush or can of pressurized air.
- 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.
- 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.
