Binoculars
Congratulations on your purchase of a pair of quality Orion bin-
oculars.
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.
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 dis-
tance 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 simi-
lar 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 dif-
ferent 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 eye-
guards are usually left in the up position for use without eyeglass-
es, as this helps prevent glare (unwanted stray light) from entering
between your eye and the eyepieces. To use the binoculars with
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.
