OMNI AZ 102 TELESCOPE
SOLAR WARNING
• Never look directly at the Sun with the naked eye or with a telescope unless you have the proper solar filter. Permanent and
irreversible eye damage may result.
• Never use your telescope to project an image of the Sun onto any surface. Internal heat build-up can damage the telescope
and any accessories attached to it.
• Never use an eyepiece solar filter or a Herschel wedge. Internal heat build-up inside the telescope can cause these devices to
crack or break, allowing unfiltered sunlight to pass through to the eye.
• Do not leave the telescope unsupervised, especially when children or adults unfamiliar with the correct operating procedures
of your telescope are present.
Save your telescope box and packing materials. We recommend packing your telescope into its box to keep it safe during
storage and transport.

INSTALLING THE TELESCOPE TUBE
INSTALLING THE STAR DIAGONAL
To attach the telescope tube to your tripod and mount:
A star diagonal attaches to the back of a refracting telescope. It contains a small prism that reflects light at a 90-degree angle so
you can view through your telescope more comfortably. Your Omni AZ 102 comes with an erect image star diagonal—a special
kind of diagonal that orients the view in the eyepiece exactly as you see it with your unaided eye. With this diagonal, you can use
your telescope as a spotting scope during the day to view land-based objects like birds, wildlife, and distant landmarks.
To install the star diagonal:
1. Remove the caps from both ends of
the diagonal.
5. Remove the objective lens cap.
2. If necessary, loosen the hand knob so
that the screw does not protrude into
the dovetail clamp.
2. Loosen the setscrew on the back of
the focuser and pull out the small dust
cap.
3. Hold the telescope tube next to the
mount and slide the dovetail bar into
the clamp on the mount.
1. Locate the dovetail bar mounted on the
side of the telescope tube.
3. Insert the smaller tube on the diagonal
into the back of the focuser. Tighten
the setscrew to secure the diagonal in
place.
4. Tighten the hand knob on the bottom
of the clamp to secure the telescope
in place.

INSTALLING THE EYEPIECE
INSTALLING THE STARPOINTER FINDERSCOPE
Your telescope comes with two Kellner eyepieces—a 10mm eyepiece and a 20mm eyepiece. The 20mm eyepiece offers lower
magnification, while the 10mm eyepiece boosts power. Always start with the 20mm eyepiece. If viewing conditions are favorable,
you can switch to the 10mm eyepiece.
When you’re ready to expand your collection, consider purchasing additional eyepieces for more viewing options. Any standard
1.25 in. telescope eyepiece will work with this telescope. Celestron offers kits with all the most popular eyepieces and filters
included.
To install the eyepiece:
The StarPointer finderscope is a red-dot sighting tool that mounts on top of your telescope tube. It will help you aim the
telescope precisely at targets so you can see them in the eyepiece.
To install the finderscope:
3. Slide the finderscope bracket into the
dovetail slot on the telescope tube
near the focuser. The large window on
the finderscope should be facing the
front of the telescope.
1. Remove the plastic tab on the
finderscope.
4. Secure the bracket by tightening the
setscrew on the dovetail slot.
2. If necessary, loosen the setscrew so
that the screw does not protrude into
the dovetail slot.
1. Loosen the setscrew on the open end
of the star diagonal.
2. Insert the silver barrel of the 20mm
eyepiece into the star diagonal.
3. Tighten the setscrew to secure the
eyepiece.

ACCESSING THE FINDERSCOPE BATTERY
NAVIGATING THE NIGHT SKY WITH YOUR OMNI AZ 102
The StarPointer finderscope uses a long-life 3V lithium battery (#CR2032), which is located on the StarPointer’s top surface. If
you plan on not using your telescope for an extended period, we recommend removing the battery for storage.
If you need to remove or replace the battery, follow these instructions:
Pointing your Omni AZ 102 at objects is easy thanks to its precise, slow-motion control knobs. Once your telescope is roughly
pointing on target, you can use the knobs to dial in its exact position.
1. Using a Phillips-head screwdriver,
loosen the battery cover screw and flip
the cover open.
1. Start by making large adjustments to
the telescope’s position so that it is
roughly pointing on target. To do this,
simply push the telescope tube in the
direction of the object you wish to
view.
2. If you are replacing the battery, install
the new one with the (+) terminal
facing outward.
2. When you are ready to make fine
adjustments, use the slow-motion
knobs. The upper knob controls the
telescope’s altitude (up-and-down)
position. Turn it clockwise to point
higher in the sky or counterclockwise
to point lower.
3. The lower knob controls the telescope’s
azimuth (left-to-right) position. Turn
it clockwise to move to the left or
counterclockwise to move to the right.
3. Place the cover back onto the
finderscope and retighten the screw
with the Phillips-head screwdriver.
• Examine devices and make sure the battery compartment is correctly
secured, e.g., that the screw or other mechanical fastener is tightened.
• Do not use if compartment is not secure.
• Dispose of used button batteries immediately and safely. Flat batteries can
still be dangerous.
• Tell others about the risk associated with button batteries and how to keep
their children safe.
WARNING: KEEP BATTERIES OUT OF REACH OF CHILDREN.

ALIGNING THE STARPOINTER FINDERSCOPE
The finderscope is one of the most important parts of your telescope. It helps you locate objects and center them in the eyepiece.
The first time you assemble your telescope, you’ll need to align the finderscope with the telescope’s main optics. It’s best to do
this during the day* using land-based targets.
* SOLAR WARNING! Never attempt to view the Sun through any telescope without a solar filter.
CHOOSE A TARGET
1. Take the telescope outside during
the day and turn on the finderscope
using the power knob. Find an easily
recognizable object, such as a
streetlight, car license plate, or sign.
The object should be as far away as
possible but at least a quarter mile
away.
ADJUST THE FINDERSCOPE
4. Without moving the telescope, use
the finderscope’s two adjustment
knobs to move it around until the red
dot appears over the object you are
observing in the eyepiece.
YOUR FINDERSCOPE IS NOW ALIGNED!
5. It should not require realignment
unless it is bumped or dropped. If you
want to test the alignment, point the
red dot at another land-based target.
Then verify the object is in the center
of the eyepiece’s field of view.
LOOK THROUGH THE FINDERSCOPE
3. With the object precisely centered
in the eyepiece, look through the
finderscope’s optical window and
locate the red dot.

CENTER THE TARGET IN THE EYEPIECE
2. Look through the telescope using your
20mm eyepiece. Move the telescope
until your chosen object lies in the
center of the view. If the image is blurry,
turn the focus knob until it comes into
sharp focus.

YOUR FIRST NIGHT OUT - THE MOON
The best and easiest celestial target for you to view first is the Moon. Try observing the Moon at different points in its phase cycle.
The best time to view the Moon is from two days after a New Moon to a few days before a Full Moon. During this period, you will
see the most detail in the craters and lunar mountain ranges.

Focus knobs
2. Look through the finderscope and
locate the red dot. Continue moving
the telescope until the dot is centered
over the Moon.
4. To get a closer look at the Moon, loosen
the setscrew on the star diagonal and
remove the 20mm eyepiece. Replace
it with the 10mm eyepiece and tighten
the setscrew to secure the new
eyepiece in place. The 10mm eyepiece
will significantly boost magnification,
making the Moon appear much larger.
You may need to adjust focus when
you change eyepieces to ensure the
sharpest image possible.
5. Using this same technique, you can
view many other celestial objects, like
planets, star clusters, and nebulae.
Celestron SkyPortal Powered by
SkySafariTM (available for iOS and
Android), is a planetarium app that can
help you locate and identify celestial
objects currently visible from your exact
location. Give it a try!
6. Scan the QR code to visit the
Celestron Tools for Astronomers
resource center. There, you’ll find
observing guides, tips and tricks, and
free downloads to guide you on your
astronomy journey.
3. Look through the 20mm eyepiece.
Gently turn the focus knobs until the
image comes in sharp.
Congratulations! You have observed
your first celestial object!

20mm
1. With the Moon visible in the sky, set
up your telescope with the 20mm
eyepiece installed and the finderscope
aligned. Move the telescope so that it
is roughly pointing toward the Moon.
Turn on the finderscope.
