Congratulations on your purchase of a precision Orion
UltraView™ binocular.With proper care and use it will provide many years of superb, enjoyable viewing. To get the
most out of your binocular, please read the following
instructions.
W arning: Never look at the Sun with binoculars or an y other
optical instrument. Severe and permanent eye damage
could result. On sunny days, children should use binoculars only with adult supervision.
Adjusting for the Distance
Between Your Eyes
The distance between the eyepiece lenses of the binocular
should be adjusted to match the distance between your
eyes, called the “interpupillary distance.” To adjust the
binocular, hold each barrel firmly; move them together or
apart while looking through the binocular with both eyes
until you see a single, round field. Make this adjustment
before focusing.
Lens Caps
Your UltraView™ binocular is fitted with a plastic cap for each
of the objective (large) lenses , and with a single cap, also called
a “rain shield,” that covers both eyepieces.The rain shield may
be threaded onto the neck strap for convenience.Keeping the
lens caps on the binocular when it is not in use will greatly
reduce dust buildup and prolong the life of the optics.
Focusing
UltraView™ binoculars feature a convenient center focusing
knob. However, because your eyes may differ slightly in their
focus, the UltraView™ also includes a right eye diopter
adjustment. Once the right eyepiece has been adjusted, you
can focus the binocular entirely with the center f ocusing knob .
Here’s what to do:
With both ey es open, rotate the right eyepiece to the full counterclockwise position, then sight on a distant subject. Cover
the right objective (front) lens with your hand.Turn the center
focusing knob until the image in the left eyepiece is sharp.
Now cover the left objective lens and focus the right side by
rotating the right eyepiece (do not adjust the center focusing
knob) until the image is sharp.The binocular is now focused
for your eyes. Make a note of the diopter setting so you can
return to it quickly in the future. With the right eyepiece now
set, focusing is achieved by rotating the center knob.
