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, using both hands, lift the binoculars up to your eyes 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.

Setting the Diopter Compensation for a Center Focus Binocular with a Right Optical Channel Diopter Compensation Dial

As most people have a difference in visual acuity between their right and left eyes, modern binoculars incorporate a mechanism that allows compensation to be adjusted between the left and right optical channels so that each eye is presented with an image that is accurately focused for it. This compensation mechanism should always be set using the following procedure whenever a new user takes up a new binocular, and should be repeated if a different user changes this compensation setting or if the compensation setting is noticed by the user to no longer be appropriate for his or her own visual requirements.

NOTE: If you normally wear eyeglasses for normal daily activities (not just reading glasses but “full time" eyeglasses) it is recommended that you also wear them while using binoculars. Simply twist the binoculars' eyecups down to their lowest position to allow the proper eye relief to be achieved while wearing the eyeglasses.

1. Pick a subject to observe approximately 50 yards or meters in the distance.
2. Cover the right objective lens with the binocular's own objective cover or with your hand.
3. View the selected subject through the binocular as you normally would but do not attempt to focus upon it yet.
4. Keeping both eyes open, use the binoculars' center focus dial to bring the image seen through the binocular into focus.
5. Without touching the center focus dial, uncover the right objective lens of the binocular and cover the left objective lens.
6. View the selected subject through the binocular as you normally would once again but do not touch binoculars' center focus dial.
7. Keeping both eyes open, determine if the subject is still in clear focus. If it is not, use the binoculars' diopter compensation dial to bring the image seen through the binocular into focus.
8. Uncover the left objective lens and view the selected subject through the binocular as you normally would. It should be clearly in focus to both eyes. If it is not, repeat this process.
9. Once the diopter compensation has been satisfactorily set for the user, the center focus dial will change the focus appropriately for the user.

If you ever notice that while using the binocular you feel a "pulling" sensation in either eye, the diopter compensation dial may have been moved. The above procedure should be used to return it to the correct balance for your eyes.

Set the Twist Up Rubber Eyecups

Twist the rubber eyecups up if you do not wear eyeglasses or twist 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! ▶️

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.

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, however, if fingerprints (which contain mild acid) do get on the glass, they should be cleaned as soon as possible to avoid damaging the coatings.

To clean the optical surfaces, we recommend the Celestron Lens Cleaning Kit (#93576), available at most photo or optical shops. Follow the instructions provided with the kit closely for best results. 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!

CAUTION! Viewing the Sun may cause permanent eye damage. ❌ Do not view the Sun with your binoculars or even with the naked eye.

Using the Smartphone Adapter

With the eyecup of the binocular twisted down to its lowest position:

1. Before attaching the adapter, look through your optic binocular, and make sure that the view is in sharp focus.
2. Open the eyepiece clamp (B) by loosening the eyepiece clamp knob (A) at the top of the eyepiece clamp.
3. Place the eyepiece clamp over the eyepiece of your optic. Tighten the eyepiece clamp knob to secure the eyepiece clamp tightly against the eyepiece.
   NOTE: Make sure to mount the clamp on a section of the eyepiece barrel that does not rotate freely, such as an eye relief adjuster.
4. Loosen the holder clamp knob (D) until the holder clamp (C) is open wide enough to accommodate the width of your phone. Once the phone is in place, tighten the holder clamp knob until the phone is secured.
   NOTE: This adapter can be used with most phone cases, but the case surface MUST be flat so it will fit in the holder correctly. Any grips, stands, rings, or raised surfaces on the case will impede the placement of the phone. All folio-style phone cases must be removed.
5. Launch the camera app on your phone. Loosen the holder alignment knob (E) and adjust the positioning of your phone camera so that it lines up with the eyepiece of your optic.
6. Once the camera is over the eyepiece and your camera is capturing the view through the eyepiece, carefully tighten the holder alignment knob to secure your phone in position.
7. If needed, adjust the focus on your optic again for the sharpest possible view.
8. You are now ready to take images and videos using your smartphone camera! ?

IMPORTANT: Always be certain the eyepiece clamp knob is sufficiently loosened before attempting to remove the adapter from the binocular's eyepiece.

CAUTION: Do not carry the binocular with the smartphone adapter in place as it may be accidentally bumped and fall off, potentially damaging the smartphone as a result. ⚠️

Using the Bluetooth Remote

Step 1: Battery Installation/Replacement

To insert or replace the battery, place your thumb in the center of the back cover, pressing inward and sliding downward to remove the battery door. The CR2032 battery should be inserted with the positive (+) side facing upward. Replace the cover.
