Orion®GrandView™65mm and 80mm ED Spotting Scopes
#51852 65mm, #51853 80mm
Congratulations on your purchase of the GrandView ED Spotting
Scope with interchangeable 1.25" eyepieces. The ED glass in the
objective lens means you’ll enjoy images with far less color distortion
than those seen in a standard scope. Your spotting scope is a high-
quality optical instrument for viewing birds, wildlife, sports events, or
anything else you want to see more closely. It will provide many years
of enjoyable viewing. Before using your spotting scope, we recom-
mend that you read through the following instructions.
Attaching the eyepieces
Your spotting scope is capable of accepting most all 1.25" standard
astronomical eyepieces. The GrandView ED includes a 1.25" zoom
eyepiece that should t most needs, but optional non zoom eyepieces
are available through Orion should you desire them. To attach your
eyepieces, loosen the large knurled collar on the eyepiece end of the
spotting scope by rotating it counter-clockwise. Insert the eyepiece
until it is fully seated, and then tighten down the collar by rotating
clockwise until snug. The GrandView utilizes a compression style
locking mechanism to clamp the eyepiece by way of this collar, in
order to hold it securely and also not scratch the side of the eyepiece
barrel. To remove the eyepiece, simply loosen the collar enough to
allow the eyepiece to slide out by hand.
Calculating the magnification
If you decide to use your own 1.25" eyepiece in the GrandView ED,
you can determine the power using the following formula by plugging
in the focal length of the GrandView along with the focal length of the
eyepiece you want to use:
Spotting Scope F.L. ÷ Eyepiece F.L. = Magnification
The GrandView 65mm has a focal length of 345.8mm, and the 80mm
is 432mm. So for example, the GrandView 80mm, used in combina-
tion with a 25mm eyepiece, yields a power of:
432mm ÷ 25mm = 17x
We don’t recommend going over a magnication of 60x during the
day, as atmospheric disturbances due to the sun heating the atmo-
sphere above hot surfaces such as roads, sidewalks and buildings,
can severely distort the image, and higher magnication will just
magnify this distortion.
Focusing
The GrandView ED spotting scopes are equipped with a dual speed
focusing knob, capable of 1:1 gross focus, and 9:1 ne focus. Point
the spotting scope so that it is aiming in the general direction of an
object at least 12' away (65mm) or 18' away (80mm). Turn the larger
focus knob (1:1 gross focus) with your ngers until the object comes
into focus. Go a little bit beyond sharp focus until the image just starts
to blur again, then reverse the rotation of the knob, just to make sure
you’ve hit the exact focus point. You can switch to the smaller focus
knob (9:1 ne focus) in order to more nely control the focus shift
and hit the exact focus of your subject. When you zoom in and out
using the included zoom eyepiece, you may have to slightly adjust
the focus position.
Using the included zoom eyepiece
The magnication is adjusted to the desired level by rotating the
middle section of the zoom eyepiece body. The arrow indicator and
magnication scale shows the magnication setting based on the
objective size of your GrandView (65mm or 80mm). Changing the
magnication may also require a slight refocusing of the spotting
scope to achieve the sharpest image. For general use, it’s a good
idea to start viewing at the lowest magnication until you’ve acquired
your viewing target. Then you can zoom in to a higher magnication
to see more detail. Note that as magnication increases, the images
will not be as bright as they are at lower powers.

Zoom eyepiece eyecups
Your spotting scope features a rotating adjustment of the eyecup on
the eyepiece. This eyecup is usually left in the up position for use
without eyeglasses. To use the spotting scope with eyeglasses, sim-
ply rotate the eyeguard downwards towards the lens. If when viewing
through the eyepiece, you see dark shadows oating around the
edges of the image when your eye is centered, you’re probably a little
too close to the lens, so try rotating the eyecup up slightly to a posi-
tion somewhere in the middle of the range.
Using the GrandView inside its case
The case for the GrandView ED spotters is designed so it can be
used on the spotter while in use. There are “doors” sewn into the
case so the tripod can be attached, the focus knob can be accessed,
and the eyepiece can be viewed through. This aids in using the spot-
ting scopes in more inclement weather, and helps protect the surface
of the spotter from scuffs and scratches.
Waterproof
The GrandView ED Spotting scopes are waterproof, and can be used in
inclement weather. However, this does not mean they can be left outside
when not in use, and they are not rated for submersion in water. If it is
raining, it’s best to use the spotters inside their case for added protection,
but the body itself will protect against rain. Also note that the spotters are
waterproof only when using the included zoom eyepiece, and may not be
waterproof if a different eyepiece is used that is not rated for wet condi-
tions. Please bring the spotting scopes back inside when not in use, and
always store indoors.
Cleaning the lenses
The lens surfaces are coated with anti-reection coatings, which can
be damaged with careless handling. Avoid touching lens surfaces
with your ngers or any coarse material. Always use lens cleaning
tissue and uid designed specically for telescope optical coatings.
Do not use regular tissue or uids made for eyeglasses or household
use. Do not disassemble the spotting scope to clean it. To clean the
lenses, rst blow air on the lens with a blower bulb or compressed air
to remove any large particles. Then brush the lens with a soft lens
brush and blow air again to remove any dislodged particles. Put two
drops of lens cleaning uid on a sheet of lens tissue (never directly
on the lens). Wipe the lens gently in a circular motion, taking care to
avoid undue pressure or rubbing. Quickly remove the excess uid by
wiping with a clean, dry lens tissue. Microber cloth works well, too.
On the objective lens, clean only a small area at a time, using a fresh
lens tissue on each area.
