Thank you for purchasing Celestron binoculars. We hope you
will have many years of pleasure with them. To maximize your
enjoyment of the binoculars, please read these instructions
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 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.
For Zoom Binocular models – To increase or decrease power, move
the zoom lever. To adjust focus, 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. 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
