S ol ar B i noc ul ars CELESTRON ECLIPSMART BINOCULARS Thank you for your purchase of the Celestron EclipSmart binocular. We are confident it will bring you many years of enjoyable solar observation. As this EclipSmart binocular is a very specialized optical instrument, please read these instructions on its use and care before using it. IMPORTANT SAFETY NOTE: If done incorrectly, direct observation of the Sun can be harmful to your vision.
So l a r Bi n oculars SET-UP AND USE OF YOUR CELESTRON ECLIPSMART BINOCULAR Because of its built-in solar filters, nothing less bright than the sun as seen from Earth should be able to be seen through an EclipSmart binocular. If you can see anything other than the Sun through these binoculars, do not attempt solar viewing with them and contact Celestron’s customer service department. SET-UP 1.
S ol ar B i noc ul ars 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. 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.
So l a r Bi n oculars USE Unlike standard binoculars, in order to keep your eyes protected, proper use of the EclipSmart binocular requires that you 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.
S ol ar B i noc ul ars 2. Adjusting Focus To focus your EclipSmart binocular, simply turn the large dial located between the two barrels until a sharp image of the solar disk is seen through the binocular. 3. Adjusting Diopter With the EclipSmart binocular safely positioned in front Focus of your eyes and the solar disk in view, without moving the Dial binocular away from your eyes: A .
So l a r Bi n oculars ACTIVITIES WITH YOUR CELESTRON ECLIPSMART BINOCULAR The Celestron EclipSmart binocular opens up the possibility of some amazing skyviewing adventures to you. After all, by using it in accordance with these instructions, you can actually view the Sun! THE GREAT AMERICAN SOLAR ECLIPSE OF 2017 On August 21, 2017, one of the greatest spectacles of our time will take place over most of North America – a total solar eclipse.
S ol ar B i noc ul ars A total solar eclipse occurs when the Moon is close enough to 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 will disappear completely.
So l a r Bi n oculars Now that you have a Celestron EclipSmart binocular to provide you a full view with both eyes at 10x magnification – the optimal way to view such an event - you are ready to be part of history.
S ol ar B i noc ul ars 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 6000°F (3300°C) compared to the normal 10,000°F (5500°C) of the rest of the photosphere.
So l a r Bi n oculars 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. If you are observing an eclipse and there are large sunspot groups on the face of the Sun, it is fun to watch the Moon slowly cover and uncover them as the eclipse progresses.
S ol ar B i noc ul ars 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, 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 the collimation will be out and they should be serviced.
So l a r Bi n oculars Avoid touching the glass surfaces but 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 and follow the instructions provided 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.
S ol ar B i noc ul ars PROBLEMS OR REPAIR If warranty problems arise or repairs are necessary, contact the Celestron technical support department if you live in the U.S.A. or Canada. If you live elsewhere, please contact the Celestron dealer you purchased the binoculars from or the Celestron distributor in your country (listings on the Celestron website). IMPORTANT: Celestron EclipSmart binoculars are specially designed with built-in Solar Safe filters.
