Care and Use
UltraView Binoculars
™
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.
Warning: Never look at the Sun with binoculars or any other optical
instrument. Severe and permanent eye damage could result. On
sunny days, children should use binoculars only with adult super-
vision.
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 bin-
ocular with both eyes until you see a single, round field. Make this
adjustment before focusing.
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 focusing knob. Here's what to do:
With both eyes open, rotate the right eyepiece to the full counter-
clockwise 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 objec-

tive lens and focus the right side by rotating the right eyepiece (do not
™
adjust the center focusing knob) until the image is sharp. The binocu-
lar 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.
Lens Caps
Your UltraView™ binocular is fitted with a plastic cap for each of the
objective (large) lenses and eyepieces. 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.
Twist-Lock Eyeguards
All UltraView™ binoculars feature convenient twist-lock eyeguards.
With less than a 1/4 turn they go from fully extended to fully retract-
ed, or vice versa. When using the binocular without eyeglasses, we
recommend leaving the eyeguards in the extended (up) position.
For viewing with eyeglasses on, retract each eyeguard turning it
counter-clockwise until fully retracted. With the eyeguards retract-
ed (down), your eyes can be positioned closer to the eyepiece
lenses for an improved field of view with your glasses on.
Mounting Your Binoculars
on a Tripod
For steadier or extended viewing, you can mount your UltraView™
binocular on any standard camera tripod by means of an optional
"L"-bracket (available from Orion and most binocular dealers).
Unscrew the small cap bearing the white tripod symbol located at
the front of the center shaft, between the two binocular barrels.
Removing this cap reveals a 1/4"-20 threaded hole into which the
top end of the L-bracket is inserted. The bottom end of the
L-bracket is threaded onto the tripod itself.
Cleaning and Care
Although your UltraView™ binocular is rubber covered, it is not
waterproof! Avoid exposure to excessive moisture.
The lens surfaces of your binoculars are vacuum-covered with
antireflection coatings that can be damaged with careless han-
dling. Avoid touching lens surfaces with your fingers or any course
material. Clean the lenses about twice a year, and more frequently
if they get dirty. The dust that builds up on them promotes mold
growth, which etches the glass and destroys the coatings. Always
use lens cleaning tissue and fluid designed specifically for multi-
coated lenses. Do not use tissue or fluids made for eyeglass or
household use.
To clean the binoculars, first puff air on the lens with a blower bulb
or with compressed air to remove the larger particles. Then it's a
good idea to brush the lens with a soft lens brush. Next, put two
drops of lens cleaning fluid on a sheet of lens tissue (never directly
on the lens). Wipe the lens gently in a circular motion, taking care
