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.

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.

ongratulations 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.
