CELESTRON ECLIPSMART BINOCULARS

Thank you for purchasing a Celestron EclipSmart binocular. We are confident it will bring you many years of enjoyable solar observation. This EclipSmart binocular is a very specialized optical instrument, so please read these instructions before using it.

IMPORTANT SAFETY NOTE: If done incorrectly, direct observation of the Sun can be harmful to your vision. Never look directly at the Sun without using equipment specially designed and tested for that purpose. Celestron's EclipSmart binoculars meet and conform to the ISO 12312-2 International Standard for safe direct visual observation of the Sun. EclipSmart binoculars should not be used for solar observation if the objective filters have been damaged, tampered with, or removed.

SET-UP AND USE OF YOUR CELESTRON ECLIPSMART BINOCULAR

Because of its built-in solar filters, you won't be able to see anything other than the Sun through an EclipSmart binocular. If you do see something other than the Sun through these binoculars, discontinue use immediately and contact Celestron's customer service department.

SET-UP

1. Adjusting the Interpupillary Distance (IPD)

Since the distance between the eyes (specifically, the distance between the centers of the pupils) varies among individuals, you'll need to adjust the distance between your binocular's two eyepieces to align with your eyes. To do this, lift the binoculars up to your eyes (using both hands) and move the two halves of the binoculars by flexing the hinge until both eyes seem to be fully covered by the eyepieces.

2. Adjusting Diopter

EclipSmart binoculars feature a diopter compensation adjustment mechanism on the right eyepiece for sharpest focus. If you do not wish to make an initial diopter correction adjustment, simply check to make sure the indicator on the right eyepiece is set to the “zero” mark prior to use. You can find a detailed explanation of how to set the diopter compensation later in this manual in the “Use” section, item 3.

3. Positioning 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.

USE

Using EclipSmart binoculars is similar to using a standard binocular—with one important difference. To ensure your eyes are always protected, position your eyes behind the eyecups BEFORE raising them into position to view the Sun.

1. Positioning the Binocular

Take up the binocular in both hands and with your view downward toward the ground in front of you, turn your body so that you are facing the direction of the Sun. Place the binocular eyecups in front of your eyes so that they are both completely covered. Then, keeping the eyecups of the binocular squarely in front of your eyes, raise your head until the solar disk appears in the binocular's field of view. If the solar disk is not immediately apparent in the field of view, slowly scan with the binocular until it becomes apparent. NEVER REMOVE THE ECLIPSMART BINOCULAR FROM IN FRONT OF YOUR EYES WHILE YOUR GAZE IS DIRECTED TOWARD THE SUN.

2. Adjusting Focus

To focus your EclipSmart binocular, simply turn the large dial located between the two barrels until you see a sharp image of the solar disk.

3. Adjusting Diopter

As solar observation with binoculars does not require the level of fine detail that other types of astronomical or terrestrial observation does, most users will not need to make any adjustments to the diopter compensation of the binocular

Focus Dia

other than setting it to the zero ("0") mark. However, if you would like to fine tune the diopter for your unique eyesight, follow these steps, making sure that you never allow yourself to look at the Sun without both eyepieces of the binocular fully in front of your eyes at all times. Begin with the EclipSmart binocular safely positioned in front of your eyes and the solar disk in view, without moving the binocular away from your eyes:

A. Keep both eyes open and use one hand to cover the right objective lens. Adjust the center focus dial until the image you see through the left eyepiece is sharp. Do not touch the center focus dial again until this process is complete.

SOLAR BINOCULARS

B. Move your hand away from the right objective lens and cover the left objective lens. If the image you see through the right eyepiece is sharp, you are finished. If it is not, adjust the diopter correction dial on the right eyepiece until it is.

C. Move your hand away from the left objective lens and assess the image as seen through both eyepieces simultaneously. The image should now be sharp and satisfying to view.

OBSERVING THE SUN

SOLAR ECLIPSES

Solar eclipses occur somewhere on Earth at least twice a year. There are two kinds of eclipses—partial and total.

A partial solar eclipse happens when the Moon passes directly between the Earth and the Sun and the Moon blocks part of the Sun's light. If the Moon happens to be near the far point of its orbit from Earth, a very special form of a partial eclipse occurs, called an

SOLAR BINOCULARS

annular eclipse. In an annular eclipse, the Moon will block out most of the Sun's disk, but leaves a small ring (or annulus) of sunlight surrounding the Moon. A total eclipse occurs when the moon is close enough to the Earth in its orbit so that it blocks the entire disk of the Sun from view. The partial phases of a total solar eclipse leading up to totality are incredible to watch. The Moon will first appear as a small dark dent in the edge of the Sun, growing to a large bite. If you are in the path of totality, the Sun will eventually become a thin crescent and then disappear completely. For a couple of minutes, daytime turns to deep twilight and bright stars and planets are visible in the daytime sky. After totality, the process reverses itself as the Sun re-emerges from behind the Moon. It is a sight that should not be missed.

Sunspots

Sunspots are dark spots that appear on the photosphere, or visible “surface” of the Sun. They usually have a dark core, called the umbra, surrounded by a lighter border, called the penumbra. They form when large disturbances in the Sun’s magnetic field cool portions of the photosphere. Sunspots are relatively cool, being only 6,000°F (3,300°C) compared to the normal 10,000°F (5,500°C) of the rest of the photosphere. Although these spots appear to be almost black, they are actually quite bright. If it were possible to remove a sunspot from the Sun and put it in the night sky, it would shine brighter than the Full Moon. They only appears to be “dark” when compared to the rest of the photosphere.

Sunspots can be big. Very big. They can range in size from 10 to 100,000 miles (16 to 160,000 km) in diameter. To put that into perspective, the Earth is only 8,000 miles (12,800 km) in diameter! Compare sunspot sizes to the relative size of the Earth in the image on the next page to better grasp the immense size of the Sun and share that WOW factor with neighbors, friends, and family.

Sunspots usually appear in pairs but can also appear in very large groups. They can last from a few days to several weeks and can change their shape, size and number as they slowly rotate across the face of the Sun. It will take about two weeks for a sunspot group to cross the Sun. Try looking at the Sun every day and draw a picture of what you see. At the end of the week, compare your drawings and you'll see how sunspots evolve.

PLANETARY TRANSIT

Planetary transits occur when the planet

Mercury or Venus passes between the Sun and Earth, allowing observers on Earth to track the planet's dark disk as it crosses the face of the Sun. This is an extremely rare event, occurring only four times over the next 50 years.

CARE AND CLEANING

Binoculars do not need routine maintenance other than making sure that the objective lenses and eyepieces are clean. If repairs become necessary, please contact Celestron's customer service department.

Collimation (optical alignment) is the biggest concern with binoculars. If your binoculars are roughly handled or dropped, there is a good chance that they could be knocked out of collimation, requiring service from Celestron's repair department. When you are not using your binocular, always store it in the case provided.

Avoid touching your binocular's 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 kit's instructions closely. If your lenses have a lot of dust or dirt accumulated, brush it off gently with a camel's hair brush or use a can of pressurized air before using the cleaning kit. You could also use the Celestron Lens Cleaning Kit or LensPen Optics Cleaning Tool made especially for cleaning binoculars.

NEVER ATTEMPT TO CLEAN YOUR BINOCULARS INTERNALLY OR TRY TO DISASSEMBLE THEM!
