1. Introduction
Important Points About Your New Telescope
1. Never look at the Sun without a proper, professionally made solar
filter. Permanent eye damage or blindness may result. Never use
the type of solar filter that screws into an eyepiece; they are sus-
ceptible to cracking under the intense heat that builds up near the
focus point and could cause severe retinal damage.
2. Like all telescopes, performance is best after the telescope has
been allowed to adjust to the outside temperature for at least 30
minutes (longer in colder climates). If possible, store the telescope
in a cool place, such as a garage. Use only low powers until your
scope has equilibrated.
2. Terminology
Altazimuth Mount A simple type of telescope mount that allows
the telescope to be moved in two perpendicular directions: up and
down (altitude) and side to side (azimuth).
Dew Cap/Glare Shield Reduces buildup of moisture on objective
lens at night; shades the objective lens from glare in daylight.
Eyepiece The part into which you look. It contains a number of
lenses that together magnify the image formed by the telescope and
allow your eye to focus on it.
Objective Lens The main lens system on the front end (opposite the
eyepiece end) of a refractor, which gathers light and brings it to a focus.
Optical Tube The main body of the telescope, which houses the optics.
3. Parts List
Qty. Desription
1 Optical tube assembly
1 Altazimuth yoke mount
1 Rubber eyeguard
1 Objective lens cap
3 Tripod legs
3 Leg bolts with large wing nuts and washers
3 Leg lock bolts with plastic finger knob
1 Tripod accessory tray
3 Accessory tray bolts with small wing nuts and washers
4. Unpacking the Telescope
Carefully unpack the telescope from the shipping container and make
sure all the parts listed above are present. Save the boxes and pack-
aging material. In the unlikely event you need to return the telescope,
you must use the original packaging.
5. Assembly
Assembling the telescope should take only about 10 minutes or so.
1. Attach each of the three wood tripod legs to the base of the metal
yoke mount using the three long leg bolts, placing a washer on
each side of the leg. The hinged accessory tray brackets should
face inward, not outward. Thread on the wing nuts but do not
tighten them yet.
2. Thread a leg lock bolt (with plastic finger knob) onto each leg.
These allow the length of the legs to be adjusted.
3. Stand the tripod and mount upright, and attach the accessory tray
to the tray brackets with the three small bolts and wing nuts pro-
vided. Do not tighten the wing nuts all the way.
4. Then, spread the legs apart as far as they will go and tighten the
accessory tray wing nuts. Also tighten the large wing nuts on the
long leg bolts.
5. Remove the two large altitude lock bolts from the optical tube.
6. Place the tube into the yoke mount and line up the holes. Thread
the altitude bolts back on to secure the telescope to the mount.
The telescope should now be ready to use.
Congratulations on your purchase of a quality Orion telescope! Your new Observer 60mm TRZ Terrestrial Zoom
Refractor will provide crisp, bright images of scenic vistas and wildlife at a continuous range of magnifications
between 30x and 90x.
The TRZ is designed primarily for terrestrial observation, incorporating an erecting prism so that images will appear
right-side up, unlike typical astronomical refractors in which the image is upside-down, or reversed left to right when
used with a 90° diagonal. We hope you enjoy the view!

WARNING: Never look directly at the Sun through
your telescope or its finder scope—even for an instant—
without a professionally made solar filter that completely
covers the front of the instrument, or permanent eye
damage could result. Young children should use this
telescope only with adult supervision.

6. Using Your Telescope
Moving and Aiming the Telescope
The Observer 60mm TRZ is easy to maneuver. To move the tele-
scope up or down, loosen the altitude lock bolts on either side of the
telescope tube until the tube moves with slight pressure. To move the
telescope sideways, turn the azimuth lock knob counterclockwise
until the tube moves freely. Then point the telescope to the desired
position and tighten the altitude and azimuth lock bolts finger-tight.
To aim the telescope, simply sight along the length of the telescope
tube. Do not point the telescope near the Sun, as serious eye dam-
age could result.
To focus the image, turn the knurled focusing ring near the eyepiece
until the image is clear and sharp. Some refocusing of the image may
be necessary after zooming in or out.
Magnification
It’s best to start observing at low power, which provides a wider field
of view, until your target object is visible in the eyepiece. Then you
can zoom to higher magnifications, if desired, by rotating the zoom
ring. Keep in mind that with higher powers, an object will always
appear fainter and less sharp (this is a fundamental law of optics).
If You Wear Eyeglasses
Fold back the rubber eyeguard to allow your eyeglasses to get closer to
the eyepiece lens. Do not remove the eyeguard completely as it pre-
vents your eyeglass lens from contacting the telescope’s eyepiece lens,
which could scratch either one or both. If the field of view in the eyepiece
is narrowed with your glasses on (producing a “keyhole” effect), you
may prefer to observe without your glasses, in which case you’ll just
need to refocus the telescope until the image you see is sharp.
Allowing Your Telescope to Equilibrate
All optical instruments need time to reach “thermal equilibrium” with the
outdoor air. The bigger the instrument and the larger the temperature
change, the more time is needed. Allow at least a half-hour for your tele-
scope to adjust to the temperature outdoors. In very cold climates (below
freezing), it is essential to store the telescope as cold as possible. If the
scope has to adjust to more than a 40° temperature change, allow at least
one hour.
You’ll get better views if you are not looking over buildings or pave-
ment, as these radiate heat, causing “heat wave” air turbulence that
will distort the image you see through the telescope.
7. Care and Maintenance
Give your telescope reasonable care and it will last a lifetime. Store it
in a clean, dry, dust-free place, safe from rapid changes in tempera-
ture and humidity. Do not store the telescope outdoors, although
storage in a garage or shed is OK. Keep the objective lens cap on the
front of the telescope when it is not in use.
General Maintenance
Your Observer 60mm refractor requires very little mechanical mainte-
nance. The optical tube is aluminum and has a smooth painted finish
that is fairly scratch-resistant. If a scratch does appear on the tube, it
will not harm the telescope. If you wish, you may apply some auto
touch-up paint to the scratch. Smudges can be wiped off with a soft
cloth and household cleaners such as Windex or Formula 409.
Cleaning the Optics
A small amount of dust or a few specks on the glass objective lens
will not affect the performance of the telescope. If dust builds up,
however, simply blow it off with a blower bulb or compressed air, or
lightly brush it off with a soft camel-hair brush. Avoid touching optical
surfaces with your fingers, as skin oil may etch optical coatings.
To remove fingerprints or smudges from a lens, use photographic-
type lens cleaning fluid and lint-free optical lens cleaning tissue. Don’t
use household cleaners or eyeglass-type cleaning cloth or wipes,
which often contain undesirable additives like silicone, which don’t
work well on precision optics. Place a few drops of fluid on the tissue
(not directly on the lens), wipe gently, then remove the fluid with
another dry tissue or two. Do not “polish” or rub hard when cleaning
the lens, as this will scratch it.The tissue may leave fibers on the lens;
these can be blown off with a blower bulb.
Never disassemble the optical tube to clean inner optical surfaces.
This should only be done by a trained optical technician.
