Congratulations on your purchase of a pair of quality Orion bin­oculars. The Resolux binoculars provide the large light grasp you

need for astronomical observation, and unlike a telescope, allow
you to use both eyes simultaneously for nighttime, or daytime,
viewing. This results in better image resolution, contrast, and
brightness than a similar sized telescope can provide. Coupled
with their wide fields of view, the Resolux binoculars will make you
feel like you’re floating in space!

Please take the time to read this instruction sheet before using
your new binoculars.

WARNING Never look directly at the Sun through
your binoculars without professionally made
solar filters, even for an instant, or permanent eye
damage could result. Young children should use
these binoculars on sunny days only with adult
supervision.

Using a Tripod

When observing with large-aperture binoculars like the Orion
Resolux, a photo tripod or some other type of binocular mount is
recommended. This is because the weight and high magnification
of the binoculars make it difficult to hold them steady by hand.

To attach the Resolux binoculars to a tripod, a binocular-to-tripod
bracket is included. The tripod bracket threads into the socket in the
binoculars’ bridge (hinge). Refer to Figure 1. Remove the threaded
cover from the socket, and thread in the tripod bracket's stud. The
bracket connects to a standard photo tripod or binocular mount via
the ¼"-20 threaded holes in its base, thus coupling the binocular
to the tripod.

Adjusting for the Distance Between Your Eyes

Hold each barrel firmly and move them together or apart so the dis­tance between the eyepieces matches the distance between your
eyes. When properly adjusted, you should see a single, round field
of view when looking through the binoculars. Make this adjustment
before you focus the binoculars.

Focusing

The Orion Resolux binoculars feature individual focus eyepieces.
This makes the binoculars mechanically more rugged than simi­lar center-focus models, and generally maintains optical alignment
better. For astronomical observation, individual focus eyepieces
are usually preferred.

Pick an object in the distance to view. At night, best focus will be
achieved by focusing on a bright star. Cover your right eye (or cover
the right objective lens of the binocular) and focus the left eyepiece
by rotating it until the image appears clearest. Then cover your left
eye (or cover the left objective lens of the binocular) and focus the
right eyepiece by rotating it until the image appears clearest. The
binoculars are now focused. If you want to view an object at a dif­ferent distance, re-focusing of both eyepieces is required.

For astronomical observation, all objects will always appear focused
at the infinity focus point. This means you only need to focus the
binoculars once per observing session. This also means you can
take note of the diopter scale setting for each eyepiece (located on
the underside of the eyepieces) when focused on an astronomical
object, and return to those settings when observing another night.
You will find this to be a great convenience.

Since everyone’s eyes focus images slightly differently, different
observers will need to refocus the binoculars for their own vision.

Fold-Down Eyeguards

Orion Resolux binoculars feature fold-down eyeguards. The eye­guards are usually left in the up position for use without eyeglass­es, as this helps prevent glare (unwanted stray light) from entering
between your eye and the eyepieces. To use the binoculars with

eyeglasses, you will need to fold the eyeguards down in order to
get your eyes close enough to the eyepieces to see the entire field
of view.

Note Regarding Waterproof Binoculars

The Resolux binoculars are nitrogen-purged and sealed to be
completely waterproof and internally fogproof. While it is imper­vious to rain, wind, splashing from a boat and humidity, do not
immerse the binocular in water under any circumstances. If the
binocular becomes wet with fresh water, merely blot it dry with
a clean cloth and clean the lens surfaces as outlined below.
Saltwater should be rinsed off completely and the binocular then
blotted dry and its lenses cleaned as outlined below. If the binocu­lar body becomes dirty, it can be cleaned with warm water and a
clean cloth. If extremely dirty, or oily, clean the body with a dilute
solution of warm water and mild soap on a cloth, then rinse with
clean water and blot dry. Do not clean lens surfaces with soap and
water!

Handling and Storage

50mm Orion Resolux binoculars come with a soft case for storage
and transport. 70mm Orion Resolux binoculars come with a foam­lined hard case for storage and transport. We recommend keeping
the binoculars in their case with the cover caps on when not in
use.

The Resolux binoculars are rubber-armored and built to withstand
minor shocks. While small impacts should not harm the binoculars,
unnecessary knocks and bumps should be avoided.

All optics, when exposed to excessive temperature changes or
high humidity, have the potential to fog up. Allow the optics to slowly
adjust to cold weather by storing the instrument (in its case) in a
cool 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, open up the case, remove the binoculars, remove the
cover caps, and let everything dry out. The binoculars should be
stored in a cool, dry place to prevent mold growth, which can dam­age the optics. This is not covered by the warranty.

Cleaning and Care of Binoculars

The lens surfaces of Orion binoculars are coated with anti-reflec­tion multi-coatings that can be damaged with careless handling.
Avoid touching lens surfaces with fingers or any coarse material.
All optics, even if stored, should be cleaned at least once 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 also damage the coatings. Always use
lens cleaning tissue and fluid that are specifically designed for
multi-coated lenses. Do not use fluids or tissues that are for eye­glasses or household use.

To clean the binocular lenses, first blow off the lens with a blower
bulb or gently wipe the lens with a lens cleaning brush to remove
the larger particles. Put a few drops of lens cleaning fluid on a fresh
piece of lens cleaning tissue (never on the lens) and gently wipe
the lens. Quickly wipe the excess fluid with a new, dry piece of lens
cleaning tissue. For larger lenses, clean only a small area at a time,
using a new tissue each time. On excessively dirty lenses, wipe
across the lens using one stroke for each tissue, alternating wet
and dry. Always avoid excessive pressure or rubbing when wiping,
as wiping too hard can scratch the lens.
