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.

ADJUSTING FOCUS

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) 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.

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.

INSTALLING THE BATTERIES - TWO LR44 BUTTON CELL

The batteries included with your binocular are for illuminating the compass, so you can see it easily in the dark. You need to install the batteries which are located in the case pocket. Unscrew the battery cap by hand and then remove the screw with a coin or screwdriver. The batteries are to be installed with the positive (+) side facing up towards you. Replace the screw and battery cap. If you will not be using the binocular for a long period of time (a few months or more), you should take the batteries out to preserve their life.

USING THE RETICLE AS A MEASURING DEVICE

View Angle

View Angle of an object is the angle between the rays from the binocular to its edges. Usually, this angle is measured at the horizontal or vertical direction, and defined as Horizontal View Angle and Vertical View Angle. A mil's reticle (shown to the right) that has a horizontal and vertical scale can measure the viewing angle of an object. The Celestron binocular uses 10 mils for each number (1,2,3,... as shown here).

Measuring the Horizontal View Angle

When the Horizontal View Angle is smaller than the horizontal scale range (-40\~+40 mils) inside the binocular, aim one edge of the object at a horizontal scale line (the center or the outmost line is selected according to the image size of the object usually) and read its value. Then read the value of the scale at which another edge was located. Add these two values and this is the measured Horizontal View Angle. The Horizontal View Angle of the target (sailboat) is 5 decade mils (50 mils).

When the Horizontal View Angle is larger than the horizontal scale range (-40\~+40 mils), use vertical line splits (for example: mast, sail, etc.) on the object can be selected to make the necessary estimated measurements in a step by step fashion.

Measuring the Vertical View Angle

Vertical View Angle measurement is similar to measuring the Horizontal View Angle. When the Vertical View Angle measurement is small, aim the intersecting point of the vertical and horizontal lines of the reticle at the lower part of the object and read the scale value at the top of the object. The angle included between the upper and lower parts of the target (lighthouse) is 6 decade mils (60 mils).

When the Vertical View Angle is larger than the vertical scale range (70 mils), it can be measured in steps, and the angle can be obtained by summing up the value of each step.

Using the Reticle to Measure Distance

The distance measurement of a target can be calculated by using the mil reticle.

The formula of distance measurement: L(km) = H(m)/

L — the distance between the observer and the object (km)

H — the height of the object (m)

ω — the View Angle of the object measured with the reticle of the binocular (mil).

When measuring the distance, estimate the width or height of the object and next measure the View Angle of the object. Accordingly, you can calculate the distance between the observer and the object using the formula.

For example:

There is an adult whose height is 1.70 m. (H = 1.70 m)

The Vertical View Angle of the adult is 4 decade mils (40 mils)

L = H / = 1.7 / 40 = 0.0425 ~km = 42.5 ~m

Therefore: the distance between the observer and the adult is 42.5 m. (for feet conversion, multiply 42.5 by 3.28).

USING THE CALCULATOR DIAL AS A MEASURING DEVICE

The Calculator Dial can be used to determine distance quickly and easily without calculation. The Calculator Dial is located inside one of the lens caps as shown. The Calculator Dial includes a triangular Angle Index Mark marked "ANGLE", a rotational Active Ring and a Fixed Scale marked "DISTANCE". There are two scales in the Active Ring, one is for View Angle and the other is Size marked "OBJECT SIZE".

First, measure the View Angle value of an object, and rotate the Active Ring and place this value at the Angle Index Mark. Then, find the division indicating the size of the object (see formula below), it indicates a point at the Fixed Scale. Look at the Fixed Scale, the distance is shown at that point on the Fixed Scale.

USING THE CALCULATOR DIAL AS A MEASURING DEVICE

For example: You observe a lighthouse, and its measured Vertical View Angle is 6 decade mils. You need to rotate the Active Ring and place the division marked "6" in the View Scale at the Angle Index Mark. Its assuming height is 12 m, the division marked "12" in the Size Scale points to the division marked "200" in the Fixed Scale. This tells us that the lighthouse's distance is 200 m from us.

The Size Scale and Fixed scale of the Calculator Dial are in a "ratio" to each other. When your observing object is too large or too small, you can zoom it tenfold or discretionarily, and zoom the measuring result in the same way. Thus, you can get more convenience, especially when you aren't familiar with diversified units.

HOW TO MEASURE AN OBJECTS SIZE (HEIGHT AND WIDTH)

According to the formula for distance measurement, you can calculate the height using:

H = L × ω. (Height = Distance × View Angle)

When measuring the size, you first estimate the distance to the object and then measure the View Angle. With these measurements, you can calculate the height of the target using the formula.

For example:

The distance is 0.6 km between the observer and the object. You can measure that the Horizontal View Angle is 6 decade mils (60 mils) and the Vertical View Angle is 3 decade mils (30 mils). So, using the formula you can get:

The height: H = 0.6 × 30 = 18 m (for feet divide 18 by 3.28)

The width: H = 0.6 × 60 = 36 m

USING THE COMPASS

The Compass is aligned with the vertical range finding scale.

The Compass by itself will only indicate direction to or from an object but not relative position. To determine position, you need a map or chart and a protractor.

The azimuth angle can be measured through the analog Compass which is built into the binocular. It shows the azimuth of the object relative to the observer. Each graduation of the Compass equals one degree of angle. When the object lies north from you, the Compass reads 360^ . The Compass degrees will increase when you turn it clockwise. 90^ means the object lies in the east from you, 180^ means the south and 270^ means the west.

In order to insure precise angle measurements, the binocular should be kept horizontal and level when reading the compass, and the object should lie in the middle of the reticle.

Note: When using the Compass, always keep in mind the local variation between magnetic north (the Compass reading) and true north. Do not put your finger or hand over the white button (compass window), as it allows light to enter the binocular, so the Compass readings can be seen.

ATTACHING YOUR BINOCULARS TO A TRIPOD

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. If your binocular is roughly handled or dropped, there is a good chance that the collimation (alignment of the optics) will be out and they should be serviced. Dirty objective lenses and/or eyepieces mean less light transmission and loss of brightness, as well as unsharp images. Keep your optics clean! When not using your binocular, store it in the soft case provided after putting the lens caps on. 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 a lens/optics cleaning kit available at most photo or optical shops. Follow the instructions provided with the kit 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. Alternately, you could use the Celestron LensPen (# 93575) made especially for cleaning binoculars. Never attempt to clean your binocular internally or try to take it apart!

CAUTION! Viewing the Sun may cause permanent eye damage. Do not view the Sun with your binocular!

Angle de vision

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated underscores where none should exist based on the GT's visual context. Hence, the OCR result is inconsistent with the Ground Truth.
