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 binocular 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 binocular.

ADJUSTING THE INTERPUPILLARY DISTANCE

WARNING: Never look at the Sun with the naked eye or with

your binocular. Looking at the Sun can cause permanent eye damage.ENGLISH I 7 TIP: 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. 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 unintentionally turns it out of position. To set the diopter compensation adjustment on a SkyMaster Pro ED binocular:

1. 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.

2. Use one of the binocular’s objective lens

covers to cover the right objective lens.

3. Select a distant stationary object such as a

tree or sign as your focusing target. Keeping both eyes open, raise the binocular to your eyes and center the selected focusing target in the binocular’s field of view.

4. 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

SETTING THE DIOPTER8 I ENGLISH

Diopter Adjustment Ring Focus Wheel adjust the center focus dial again until the end of this process.

5. Lower the binocular and move the objective

lens cover to cover the left objective lens.

6. 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.

7. Lower the binocular 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 binocular.) Continued page 7.ENGLISH I 9

POSITIONING THE EYECUPS

The SkyMaster Pro ED features specially designed twisting eyecups that may be set at fully retracted, mid-point, or fully extended positions. To position the eyecup, simply grasp it with your thumb and forefinger and twist it clockwise until it reaches the next stopping point detent.10 I ENGLISH ATTACHING FILTERS Celestron SkyMaster Pro ED binoculars feature a 1.25” astronomical filter-compatible eyepiece design. To attach a filter to an eyepiece: l Position the binocular’s eyecup in the fully retracted position. l Carefully align the filter’s threads with the threads surrounding the eyepiece lens. l Twist the filter gently so that the threads engage smoothly and continue turning until the filter reaches a natural stopping point. l Repeat the process with the other eyepiece. For the most comfortable use of the binocular with filters mounted into the eyepieces, position the eyecups in the fully extended positions so that the rims of the eyecups are higher than the top edge of the filters.ENGLISH I 11 Mounting the binocular on a tripod allows for added stability and comfort during prolonged viewing. SkyMaster Pro ED 7x50mm and 15x70mm The SkyMaster Pro ED 7x50mm and 15x70mm feature built-in threads that allow the binocular to be attached to a tripod using a Celestron binocular tripod adapter (sold separately). You can access these threads by unscrewing the logo plate found on the front of the binocular’s center hinge. To attach the binocular to a tripod, follow the instructions that came with your adapter.

TRIPOD ADAPTABILITY12 I ENGLISH

SkyMaster Pro 20x80 The SkyMaster Pro 20x80 features a built-in tripod adapter that allows the binocular to be attached to a tripod without the need for any additional accessories. This built-in adapter is attached to the center support rod of the binocular and slides along the rod so you can find the perfect balance point when attaching the binocular to a tripod. To attach the binocular to a tripod: l Thread the ¼-20” mounting bolt of the tripod’s mounting plate into the bottom of the tripod adapter until it is secure. l Mount the plate with the binocular attached to the head of the tripod and secure it in position. Keep a firm grip on the binocular as it has not yet been adjusted for balance. l Loosen the knob on the top of the binocular’s built-in tripod adapter until the binocular’s center column moves freely through it. Celestron StarPointer Finderscope not included.ENGLISH I 13 WATERPROOF / FOGPROOF

SkyMaster Pro ED binoculars are waterproof and filled with dry nitrogen gas to prevent the housing from fogging internally.

1. Protect the binocular from impact and do not

force any 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

4. When storing for an extended period, 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. Your Celestron binocular will provide you with years of dependable service if it is cared for and stored correctly. l Holding on to the binocular, move it back and forth until it achieves a stable point of balance. l Lighten your grip on the binocular to test whether you have achieved balance. If you haven’t, continue moving the binocular back and forth until it balances. l Turn the knob on the top of the binocular’s built-in tripod adapter until it is fixed securely in position.14 I ENGLISH

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 using a lens/optics cleaning kit available at most photo or optical shops. Follow the directions supplied with the cleaning kit for best results.
