Adjusting the Interpupillary Distance (IPD)
To adjust this distance, lift the binocular to your eyes using both hands and look through them at a distant object. Move the two barrels (halves) of the binoculars closer together or further apart until you see a single, clear image. Check that the interpupillary distance is set correctly every time you use your binoculars.
Setting the Diopter
Whenever you begin using a new binocular or resume using a binocular after someone else has been using it, ensure the diopter compensation adjustment dial is set correctly for your eyes. Once the dial is adjusted, you will not need to adjust it again unless someone changes the setting or intentionally turns it out of position. To set the diopter compensation adjustment on SkyMaster Pro ED binoculars:
Set the dial at the zero point by placing the index mark on the diopter adjustment ring opposite the zero or middle on the scale.
Use one of the binocular’s objective lens covers to cover the right objective lens.
Select a distant stationary object such as a tree or sign as your focusing target. Keeping both eyes open, raise the binoculars to your eyes and center the selected focusing target in the binocular’s field of view.
Still keeping both eyes open while viewing the target, use the center focus dial to bring the target into sharp focus in the left eyepiece. Once the object is in focus, do not adjust the center focus dial again until the end of this process.
Lower the binoculars and move the objective lens cover to cover the left objective lens.
Still keeping both eyes open, find and view the target again. This time, use the diopter adjustment ring to bring the target into sharp focus in the right eyepiece.
Lower the binoculars and uncover the right eyepiece. You should now be able to view through both eyepieces and adjust focus using the center focus dial while maintaining the proper amount of compensation between your two eyes. If the diopter adjustment ring is ever moved, repeat this process. (You may be wondering why you kept both eyes open even though you could only see through one optical channel at a time. It’s because when you close one eye, your visual acuity in the other eye changes slightly due to the intricate and complex arrangement of muscles surrounding both eyes. By keeping both eyes open, your vision is as it would be during regular use of the binoculars.)

NOTE: Your binocular has a diopter indicator Note your preferred setting for faster focus adjustment the next time you use your binocular.

Set the Eyecups

If you wear eyeglasses for nearsightedness, you should wear them when using binoculars. You may not be able to obtain focus at infinity without them. Extend the eyecups if you will not be wearing eyeglasses while using the binocular, or retract them if you will be. When you are finished using the binocular, retract the eyecups for storage. Now you are ready to use your binoculars. Enjoy the view!
Additional Features
To learn more about how to mount your Celestron SkyMaster Pro ED binocular on a tripod for steady viewing, how to attach astronomical filters to the eyepieces, and how to set the eyecups to accommodate them, please refer to the complete instruction manual on the Celestron website at: www.celestron.com/pages/manuals.

Care and Cleaning

Binoculars do not need routine maintenance other than making sure that the objective lenses and eyepieces are kept clean. If repairs becom necessary, your binoculars should only be service by the manufacturer or a third-party repair company authorized by the manufacturer.

Collimation (optical alignment) is the biggest concern with binoculars. If your binoculars are roughly handled or dropped, they may becom out of collimation and should be serviced.
Dirty objectives and/or eyepieces mean less light transmission, loss of brightness, and unclear images.
When you are not using your binoculars, store them in the case provided. Avoid touching the glass surfaces.
If fingerprints (which contain mild acid) do get on a lens, clean it as soon as possible to avoid damaging the optical coatings.
To clean the optical surfaces, we recommendusing the Celestron Lens Cleaning Kit (#93576) or good quality camera cleaning kit. Follow the instructions provided closely.
If you have a lot of dust or dirt accumulated, remove it gently with a natural hair brush and/ or a can of pressurized air before using the cleaning kit. Alternately, you could use the Celestron LensPen Optics Cleaning Tool (#93575) made especially for cleaning fine optical instruments.
Never attempt to clean your binoculars internally or take them apart.

Caution! Viewing the Sun may cause permanent eye damage. Do not view the Sun with your SkyMaster binoculars or the naked eye.
