ORION TELESCOPES & BINOCULARS 40910 User manual

Congratulations on your purchase of the Orion 80mm ED Binocular Spotting Scope.
This innovative, premium-quality instrument provides comfortable binocular-style
viewing for high-power visual pursuits during both daytime and nighttime. This
spotting scope incorporates the Premium Linear BinoViewer—which is also sold
as an accessory for use with other telescopes—on a 360-degree swivel collar.
Just pop it on a sturdy tripod or equatorial mount and you’ll be ready to start exploring your
surroundings near and far in 3D-like magnicence! Please review these instructions before
using the product for the rst time. If you run into any problems, contact Orion Customer
Support at 800-676-1343 or by email at www.OrionTelescopes.com/contactus.
WARNING: Never look directly at the Sun through your
telescope—even for an instant—without a professionally
made solar lter that completely covers the front of
the instrument, or permanent eye damage could result.
Young children should use this telescope only with adult
supervision.

•12.5mm Edge-On Eyepieces (x2)
•Dovetail bar
•Heavy Duty Waterproof Case
Refer to Figure 1 below to familiarize yourself with the parts of the
spotting scope.
Mounting the Binocular Spotting
Scope
Field Tripod
A sturdy tripod with pan head that can support at least 7 lbs. is
required to ensure stable support of the 80mm ED Binocular Spotting
Scope.
To mount the telescope, rst remove the quick-release (QR) plate
from the pan head. Attach the QR plate to the bottom of the spotting
scope’s mounting bracket by threading the ¼"-20 post into one
of the threaded holes of the bracket (Figure 2A). Make sure this
connection is tight. Then reattach the QR plate with scope attached
to the pan head and secure in place (2B). Adjust the tripod height so
that the spotting scope’s eyepieces are positioned at a comfortable
viewing height.
Equatorial Mount
For astronomical viewing with the 80mm ED Binocular Spotting
Scope, an equatorial (EQ) mount is useful as it allows easy manual
tracking or motorized tracking of the sky. To attach the scope to an
EQ mount, you may nd it helpful to use the included V-style dovetail
bar (Figure 3A). This bar is compatible with EQ mounts equipped
with a Vixen-style dovetail saddle.
Attach the dovetail bar to the bottom of the telescope’s bracket with
the two screws as shown in Figure 3B. You will need a 5/32" or M4
Allen wrench for the screws. Then insert the dovetail bar with scope
attached into the saddle of the EQ mount and tighten it down (3C).
One great feature of the 80mm ED Binocular Spotting Scope is
that the BinoViewer can be rotated 360 degrees. So even when
the telescope is angled in an awkward position toward a celestial
target, you can rotate the BinoViewer so that the eyepieces are
in a comfortable viewing position (Figure 4)—no neck craning
necessary!
Installing the Eyepieces
Insert the two 12.5mm eyepieces into the left and right eyepiece
collars of the BinoViewer (Figure 5). If the barrel won’t go in, rotate
the red twist-tight collar counterclockwise a turn or so and try again.
Once the eyepiece is inserted, rotate the twist-tight collar clockwise
to secure the eyepiece in place.
The included 12.5mm eyepieces have 20mm eye relief, 55-degree
apparent eld of view, and produce 40x magnication.
You can use other pairs of 1.25" telescope eyepieces in the 80mm
ED Binocular Spotting Scope to give you additional magnication
options.
Adjusting the Interpupillary
Distance
The two halves of the Premium Linear BinoViewer can be moved
inward or outward (i.e., linearly) to accommodate the distance
between your two eyes, or the “interpupillary distance” (IPD). While
looking into the eyepieces with both eyes, grasp both sides of the
BinoViewer housing and to push inward or pull outward until the
two single images merge into one. Once you’ve done that, note
the number on the IPD scale, which ranges from 58mm to 74mm
(Figure 6). Then you can quickly set it to the same IPD next time you
use the scope.

Focusing
With the two eyepieces installed, cover or close you right eye and
look into the left eyepiece with your left eye. Adjust the focus using
the telescope’s rubber focusing ring (refer to Figure 1) until you get
a sharp image.
Now close or cover your left eye and look into the right eyepiece with
your right eye. Check if the image you see is clear and sharp. If it is,
you’re done. If the image is blurry, rotate the BinoViewer’s diopter
focusing ring (Figure 6)—not the telescope’s focus ring—until the
right image is sharp.
Now the image in both eyepieces should appear sharp and clear.
From here on, to adjust the focus while observing you should use
only the telescope’s focusing ring.
Using Filters
The Edge-On 12.5mm eyepieces included with the spotting scope
have barrels that are threaded to accept optional Orion 1.25" lters.
You simply thread the lter into the end of the barrel. Filters can be
used to cut glare when viewing the Moon (e.g., our #5662 Moon Filter)
or to combat the contrast-reducing effects of light pollution (e.g., the
#5660 SkyGlow Broadband Filter), to name just a couple of uses.
Storage
Keep the 80mm ED Binocular Spotting Scope and accessories in the
waterproof, padded hard case when not in use (Figure 7). It is also
recommended to leave the scope in a dry place with caps off and
case open overnight to let it completely dry out after use. Store the
telescope indoors or in a dry garage; storage in a humid environment
may result in mold growth on the optical surfaces that can destroy
optical coatings. This is not covered by the warranty.
Cleaning of the Optics
The lens surfaces of the 80mm ED Binocular Spotting Scope are
coated with anti-reection multi-coatings that can be damaged with
careless handling. Avoid touching lens surfaces with ngers 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 multicoated lenses. Do not use uids or tissues that are
for eyeglasses or household use. Never attempt to disassemble the

the two eyepieces at a comfortable viewing angle.

which secure the eyepieces with just a clockwise twist.

your scope clean and protected when it’s not in use.
Figure 6. The right diopter adjustment is used to achieve proper
focus, and the interpupillary distance (IPD) scale aids in setting, and
later resetting, the correct distance between the eyepieces for your eyes.

spotting scope or eyepieces in order to clean them; this can also void
the warranty.
To clean the telescope’s objective lens and the eyepiece lenses, rst
blow off the lens with a photographer’s blower bulb or gently wipe the
lens with a soft 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 directly on the lens) and gently wipe the lens.
Quickly wipe the excess uid 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.
