Binocular Instructions
Warning: Never look at the Sun with binoculars or any other
optics. Children should use optics on sunny days with adult
supervision. To use any Orion® binoculars, simply adjust the
distance between the binocular halves to fit your eyes, and
turn the center focus wheel until the image is sharp. For
more details, read on.

Adjusting the Distance Between Your Eyes
Hold each barrel firmly and move the two barrels together to match the
distance between your eyes. You should see a single round field with
both eyes. Make this adjustment before you focus.
The small center wheel between the two barrels is for focusing
the binoculars. The center wheel focuses both barrels simultaneously. Turn the wheel until the image is clearest. The left
eyepiece does not rotate; the right one does. The rotating right
eyepiece is called the diopter adjustment.
Diopter Adjustment
Because all eyes are slightly different, Orion binoculars feature a
“Right Eye Diopter Adjustment.” The purpose of this is to compensate for slight differences between a person’s two eyes. With
both eyes open, cover the right objective lens (front) with your
hand. Turn the center-focusing wheel until the image in the left
side is sharp. Again, cover the left objective lens (front) with your
hand and focus the right side by rotating the right eyepiece until
the image is sharp. The binocular is now adjusted to your eyes.
Make a note of the diopter adjustment and turn the right eyepiece
to that diopter adjustment whenever you look through them. Once
you make this adjustment, you do not have to touch the diopter
adjustment. Simply focus both sides by turning the center wheel.
Attaching the Tripod Mount
Most Orion binoculars can be attached to a standard photo tripod by
means of an “L” bracket binocular tripod mount. Unscrew the small
(approximately 1/2") cap that is located at the front of the center shaft,
between the binocular halves. This is the objective end of the shaft
that contains the center focusing wheel. Removing this cap reveals a
small 1/4"-20 threaded hole. The male threaded portion of the tripod
“L” bracket screws into this hole. Screw the tripod male-threaded
mounting screw into one of the holes on the bottom of the “L” bracket binocular tripod mount (some of the mounts contain two holes for
adjustable positioning).
Roll-Down Eyecups
Most Orion binoculars feature roll-down eyecups. The eyecups
are usually left in the up position for use without eyeglasses. To
use the binocular with eyeglasses, simply roll down the eyeguard by folding down one side, then slide your fingers across to
the opposite side of the eyepiece.
Cleaning and Care of Binoculars
The lens surfaces of Orion binoculars are coated with anti-reflection
coatings that can be damaged with careless handling. Avoid touching surfaces with fingers or any coarse material. Most binoculars,
eyepieces, and camera lenses are cared for in a similar manner. All
optics, even if stored, must be cleaned approximately twice a year
or whenever they are dirty. The dust that builds up on coatings promotes mold growth, which etches glass and destroys coatings.
Avoid over-cleaning; it can damage the coatings. Always use lens
cleaning tissue and fluid that are specifically designed for multi-coated lenses. Do not use fluids or tissue that are for eyeglass or
household use.
To clean the binoculars, blow off the lens with a blower bulb to
remove the larger particles. Make sure your hands are clean.
Have several pieces of tissue ready. Put two drops of lens cleaning fluid on a piece of lens cleaning tissue (never on the lens).
Gently wipe the dirt off the lens. Quickly wipe the excess with a
new, dry piece of lens cleaning tissue. On larger lenses, clean
only a small area at a time, using new tissue each time. On
excessively dirty lenses, wipe across using one stroke for each
tissue, alternating wet and dry. The more fresh, clean lens tissue
you use, the less likely you are to scratch your lenses. Always
avoid excessive pressure or rubbing. It is better to leave a tiny
amount of dirt on the lens than to use too much pressure and
destroy the coatings.
Storage and Cold Weather
All optics, when exposed to excessive temperature changes or high
humidity, have the potential to fog up. Always allow the optics to
slowly adjust to cold weather by storing the instrument (in its case) in
a cold area such as an unheated garage or the trunk of a car for a
few hours before use. When bringing the instrument back inside a
warm house, store it in a cool area for one to two hours. It is very
important to then open up the case, remove the instrument, then
remove the caps, and let everything dry out overnight. The instrument should be stored in a cool dry place; storing it in a moist
environment will result in mold growth and destroy the optics. This is
not covered by warranty.
All Orion binoculars are warranted to be free of defects in materials and workmanship for at least one year (longer on many
models). See the warranty sheet enclosed with your specific pair of
binoculars. It specifically does not cover abuse, modification, mishandling, self-repair, or normal wear and tear. Binocular collimation
(alignment of the two barrels) is specifically not covered beyond the
30-day return period. Binoculars go out of collimation only if they
are dropped or bumped. Binocular collimation (and cleaning) are
considered routine maintenance and should be done every five
years, or when necessary. Charges usually start at $35.
