Congratulations on your purchase of a pair of quality Orion bin-
oculars. The GiantView 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 day-
time, 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 GiantViews 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 the Tripod Mounting Post

When observing with large-aperture binoculars like the Orion 
GiantViews, a photo tripod or some other type of binocular mount 
is recommended. This is because the weight and high magnifica-
tion of the binoculars make it difficult to hold them steady by hand. 
To attach the 70mm GiantView binoculars to a tripod, an optional 
binocular-to-tripod L-adapter bracket is required; this is available 
from the Orion catalog or telescope.com. The L-adapter threads 
into the socket on the binoculars’ bridge (hinge). Refer to 

Figure 

1. Remove the threaded cover from the socket, and thread in the 
L-adapter’s stud. The L-adapter 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.
The 80mm and 100mm GiantView binoculars can be attached to 
a standard photo tripod by means of its integral tripod mounting 
post (

Figure 1). Simply thread the ¼"-20 stud of your tripod into the 

threaded socket on the underside of the mounting post. The tripod 
mounting post can be positioned anywhere along the brace rod to 
optimize balance. To do this, first loosen the large knurled knob on 
top of the post (Figure 1). Then, grip the binoculars and move them 
forward or backwards relative to the post until the balance seems 
about right. Re-tighten the knurled knob on the post when done.
The brace rod allows positioning of the binoculars relative to the 
tripod mounting post, but also provides additional stability for the 
binocular barrels. This helps maintain structural rigidity and optical 
alignment.

Adjusting the Distance Between Your Eyes 

(Interpupillary Distance)

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 GiantView 15x70 and 25x100 feature individual focus 
eyepieces.  The 16x80 and 20x80 ED GiantView binoculars feature 
a center focus with right diopter adjustment.
For the individual eyepiece focus models (15x70 and 25x100), 
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 differ-
ent distance, re-focusing of both eyepieces is required.
To focus the center focus ED models (16x80 ED and 20x80 ED), 
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 objective lens and focus the right side by rotating the right 
eyepiece diopter ring (do not adjust the center focusing knob) until 
the same object you focused on previously is sharp. The binocular 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 only rotating the center knob.
Since everyone’s eyes focus images slightly differently, different 
observers will need to refocus the binoculars for their own vision.

Fold-Down Eyeguards 

Orion GiantView 15x70 and 25x100 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

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.
