bracket on the side of the tray is a holder for the GoTo
hand controller.
It is a good idea to adjust the height of the tripod before
attaching the fork arm and optical tube. Minor adjustments
can be made later. To adjust the height of the tripod legs:
3. Loosen the tripod leg clamp knob located on the side of
each leg (Figure 1).
4. Extend the inner portion of each leg to the desired
length.
5. Tighten the tripod leg clamp knobs to secure each leg in
place.
Also, be sure to tighten the large wingnuts at the top of each
leg, where it attaches to the tripod mounting platform.
Attaching the Mount Arm to the Tripod
1. Place the mount arm base inside the tripod mounting
platform. See Figure 4.
2. Thread the coupling screw into the hole at the bottom of
the mount arm base and tighten with the large coupling
knob.
Attaching the Telescope Tube to the Mount Arm
1. Unthread the tube lock bolt until the bolt tip is not
protruding into the saddle slot.
2. Slide the tube dovetail bar into the saddle on the mount
arm as shown in Figure 5, and secure it by tightening the
tube lock bolt.
WARNING: NEVER ATTEMPT TO MOVE THE TELE-
SCOPE BY HAND! Otherwise, the gears and motors may
be damaged. Move the telescope only electronically with
the hand controller.
Inserting the Star Diagonal (Mak-Cass and Refractor)
and/or Eyepiece
A star diagonal is used with the Maksutov-Cassegrain and
refractor models to divert the light at a right angle from the light
path of the telescope. This allows you to observe in positions
that are more comfortable than if you were to look straight
through. A diagonal is not used with Newtonian reflectors;
none is included with the StarSeeker reflector models.
To attach the star diagonal:
1. Remove the protective dust cap from the 1.25" accessory
adapter.
2. Loosen the two thumbscrews on the 1.25" adapter and
slide the chrome portion of the star diagonal into the
adapter (see Figure 6).
Figure 5. Insert the dovetail bar on the optical tube into the
saddle on the mount arm.

The eyepiece, or ocular, is the optical element that magnifies
the image focused by the telescope.
The eyepiece fits directly into the 1.25" accessory adapter or
star diagonal. To install one of the included eyepieces:
1. Loosen the thumbscrew on the 1.25" adapter or star
diagonal.
2. Slide the chrome barrel of the eyepiece into the adapter
or diagonal (Figure 7).
3. Tighten the thumbscrew to hold the eyepiece in place.
Installing the EZ Finder II
Before installing the EZ Finder II (Figure 8) on the telescope,
you may need to insert the included CR2032 3V lithium but-
ton cell battery. In some cases, the battery may have been
installed at the factory. If there is a small plastic tab sticking
out from the battery compartment cover, you must remove it
for the battery to make contact with the EZ Finder’s electron-
ic circuitry. The tab can then be discarded. If the battery was
not installed at the factory and is provided separately, you will
have to install it, as follows:
1. Insert a small, flat-blade screwdriver into the notch in
the battery compartment cover and gently pry it off
(Figure 8).
2. Slide the battery under the retaining clip with the positive
(+) side facing down (touching the clip).
3. Then press the battery compartment cover back on.
Should the battery die, replacement CR2032 batteries are
available at many stores where small batteries are sold or
online.
To attach the dovetail mounting bracket to the EZ Finder II,
loosen the two thumbscrews on the bottom rail of the EZ
Finder II. Slide the EZ Finder II onto the bracket and tighten
the two thumbscrews (See Figure 8). Then simply slide the
mounting bracket’s foot into the dovetail mounting shoe as
shown in Figure 9 and tighten the thumbscrew on the shoe to
secure the mounting bracket.
The EZ Finder II should be oriented so that the sight tube is
facing the front of the telescope, as shown. Tighten the thumb-
screw on the dovetail shoe to secure the EZ Finder II in place.
Learning to Use the
EZ Finder, Eyepieces,
and Focuser
The EZ Finder II
The EZ Finder II works by projecting a tiny red dot (it is not
a laser beam) onto a lens mounted in the front of the unit.
When you look through the EZ Finder II, the red dot will appear
to float in space, helping you to pinpoint your target object
(Figure 10). The red dot is produced by a light-emitting diode
(LED) near the rear of the sight. The 3V lithium battery pro-
vides the power for the diode.
For the EZ Finder II to work properly, it has to be aligned with
the telescope. When the two are aligned, a celestial object that
is centered on the EZ Finder II’s red dot should also appear
in the center of the telescope’s eyepiece. Alignment of the
EZ Finder II is easiest during daylight, before observing at
night. Aim the telescope at a distant object such as a tele-
phone pole or roof chimney and center it in the telescope’s
eyepiece. The object should be at least 1/4 mile away. Now
turn on the EZ Finder II and look though it. Without moving the
main telescope, use the EZ Finder II’s azimuth (left/right) and
altitude (up/down) adjustment knobs (see Figure 8) to position
the red dot on the object in the eyepiece. When the red dot is
centered on the distant object, check to make sure that the
object is still centered in the telescope eyepiece. If it isn’t, re-
Figure 8. The EZ Finder II’s On/Off and adjustment knobs.

center it and adjust the EZ Finder II’s alignment again. When
the object is centered in the eyepiece and on the EZ Finder’s
red dot, the EZ Finder II is properly aligned with the telescope.
Once aligned, EZ Finder II will usually hold its alignment even
after being removed and remounted. Otherwise, only minimal
realignment will be needed.
Turn the ON/OFF knob (see Figure 8) clockwise until you
hear the “click” indicating that power has been turned on. Look
through the back of the reflex sight with both eyes open to
see the red dot. Position your eye at a comfortable distance
from the back of the sight. In daylight you may need to cover
the front of the sight with your hand to be able to see the dot,
which is purposefully quite dim. The intensity of the dot is
adjusted by turning the ON/OFF knob. For best results when
stargazing, use the dimmest possible setting that allows you
to see the dot without difficulty. Typically a dimmer setting is
used under dark skies and a brighter setting is needed under
light-polluted skies or in daylight.
At the end of your observing session, be sure to turn off the
ON/OFF knob on the EZ Finder II.
Eyepieces and Magnification
Eyepieces are commonly referred to by their focal length and
barrel diameter. The focal length of each eyepiece is typi-
cally printed on the eyepiece body. For example, StarSeeker
telescopes include two 1.25" diameter eyepieces; one with
25mm and the other with 10mm focal length. The longer the
focal length (i.e., the larger the number), the lower the eye-
piece power or magnification; and the shorter the focal length
(i.e., the smaller the number), the higher the magnification.
Generally, low or moderate power will produce the sharpest
images when viewing.
You can change the magnifying power of your telescope just
by changing the eyepiece (ocular). To determine the magnifi-
cation of your telescope, simply divide the focal length of the
telescope by the focal length of the eyepiece used.
Telescope Focal Length (mm) = Magnification
Eyepiece Focal Length (mm)
For example, the StarSeeker III 114mm reflector has a focal
length of 500mm, which when used with the supplied 25mm
eyepiece yields 20x magnification:
500mm = 20x
25mm
The magnification provided by the 10mm eyepiece is:
500mm = 50x
10mm
Although the power can be varied, each instrument under
average skies has a limit to the highest useful magnification.
The general rule is 2x per millimeter of aperture is as high as
you can reasonably go (with optional eyepiece and possibly a
Barlow lens). For example, the StarSeeker III 114mm reflec-
tor has a primary mirror that’s 114mm in diameter. So 114mm
times 2x per millimeter = 114 x 2 = 228. Thus, 228x is the
highest useful magnification one can normally achieve under
ideal seeing conditions with this telescope. (Trying to go higher
would likely just result in dim, blurry images.) Although this is
the maximum useful magnification, most observing will yield
best results at lower powers.
Focusing
To focus, if you have a StarSeeker III Newtonian reflector or
refractor telescope, simply turn either of the two focus wheels
on the focuser (see Figure 6, for example) until the image looks
sharp. For the Maksutov-Cassegrain models, the focus knob
resides to the right of the visual back, or accessory adapter.
Make sure you’re aimed at something far off in the distance. If
you don’t see an image at first, keep turning the focus knob in
one direction while looking through the eyepiece; if you reach
the end of the focuser travel start turning the focus knob in the
other direction. Eventually, you should see the object you’re
aimed at come into view. After going just past the focus point in
one direction, and then in the other direction, you will then be
able to home in on the exact focus point, at which the image
looks sharpest.
Powering the StarSeeker III
Your StarSeeker III mount can be powered by the supplied bat-
tery pack, or by an optional AC-to-DC adapter or Dynamo Pro
12V DC field battery. The battery pack requires 8 user-sup-
Figure 9. Insert the EZ Finder II into its dovetail shoe in the

plied AA alkaline batteries. To power the StarSeeker III mount,
insert the plug of your desired power supply into the 12V jack
located on the mount arm (Figure 11). Once the power sup-
ply is plugged in, the LCD on the StarSeeker’s hand control-
ler will light up and display the opening message. To turn the
StarSeeker III mount off, simply disconnect the power supply
cable from the jack on the mount. (There is no On/Off switch.)
The SynScan GoTo Hand
Controller – Overview
The “command center” of the StarSeeker telescope is the
SynScan GoTo hand controller. In conjunction with the pre-
cision servo motors built into the mount, the user-friendly
SynScan controller allows automated, pinpoint slewing of the
telescope to any celestial object in its 42,900-object database,
saving you the trouble of manually searching for them.You can
even tour a pre-selected list of the finest showpiece objects
visible in tonight’s sky with just a few button pushes. Once your
target object has been acquired, the mount tracks its motion
across the sky to keep it in the field of view.
Keypad Layout and Connection Ports
The hand controller’s two-line liquid crystal display (LCD) is
backlit for comfortable viewing. The contrast of the text and the
brightness of the red backlight are both adjustable.
There are four categories of control keys on the hand control-
ler (Figure 12A):
1) Mode keys
2) Directional keys
3) Scroll keys
4) Dual Purpose keys
Mode Keys
The three mode keys are ESC, ENTER, and SETUP.
• ESC is used to escape from a certain command or go back
a level in the menu tree.
• SETUP is a quick hot key that takes you to the Setup
submenu.
• ENTER is used to select the functions and submenus in the
menu tree, and to confirm certain functional operations.
Direction Keys
The direction keys (Up, Down, Left, Right) allow the user to
have complete control of the mount at almost any step in
operation. These controls are locked out when the telescope is
slewing to an object. The direction keys are very helpful when
initially aligning the mount, centering objects in the eyepiece
field of view, slewing, and manually guiding. The left and right
direction keys can also be used to move the text cursor when
entering data on the hand controller.
Scroll Keys
The Up and Down scroll keys allow you to scroll up and down
within the menu tree or selections displayed on the hand con-
troller screen.
Dual Purpose (Shortcut) Keys
The Dual Purpose keys serve two distinct purposes. They are
used for data entry and as quick-reference (shortcut) keys.
• TOUR: Takes you on a preset tour of the best night sky
objects visible
• RATE: Changes the speed of the motors when the
directional buttons are pressed. There are 10 slew speeds
to choose from, with 0 being the slowest and 9 being
the fastest.
• UTILITY: Displays functions such as “Show Position”,
“Display Time”… etc.
• USER: Gives access to up to 25 user-defined coordinates
• INFO: Identifies the object(s) the mount is currently
pointing to
• NGC, IC, M, PLANET, and OBJECT: Allows direct access
to database of thousands of objects
Connecting the SynScan Hand Controller
1. Plug the larger of the two connectors on the coil cable
into the RJ-45 jack on the bottom of the SynScan hand
controller (Figure 12B).
2. Then plug the smaller connector into the RJ-12 port at
the base of the mount arm (Figure 11).
NOTE: The other, RJ-12 jack on the bottom of the hand
controller is a serial port used for controlling the tele-
scope via a computer running a compatible astronomy
software program, or for updating the SynScan’s firm-
ware, both of which are covered later.
Initial Setup
1. Make sure the mount is level to the ground.
2. After installing eight AA batteries into the battery case,
plug the power cable from the battery pack into the
power jack on the mount arm (Figure 11). The hand
controller will issue a long beep and display the firmware
version. Press ENTER.
Figure 11. Jacks for the power cable and hand controller
cable are located at the bottom of the mount arm.

3. The hand controller will scroll a warning message about
the danger of viewing the Sun with a telescope without
a properly fitted solar filter. Press ENTER to confirm you
have read the warning message and proceed to the next
step. Press ESC to return to the previous step.
4. The LCD screen will display “Enter Location” on the first
line, and longitude and latitude values on the second line.
Enter the latitude and longitude of your current location using
the numeric keypad and scroll buttons. If you do not know the
latitude and longitude coordinates of your viewing location,
consult an atlas or look them up on the internet (i.e., search
“[your location] coordinates”).
• Use the scroll keys to choose between E or W (for
longitude) and N or S (for latitude).
• Press ENTER to confirm the entered coordinates and
proceed to the next step.
NOTE: Latitude and longitude coordinates must be
entered in degrees and arcminutes. If your atlas or other
reference source provides coordinates in decimal val-
ues (i.e., latitude = 36.95 N), you must convert that into
degrees and arcminutes (i.e., latitude 36.95 N = latitude
36°57’ N). There are 60 arcminutes in 1 degree.
5. Enter the current time zone in which you are observing
in hours (see Appendix B), using the scroll keys and
numeric keypad (+ for East, – for West) The “+” sign is
used for time zones in the Eastern Hemisphere (Europe,
Africa, Asia, Oceania), while the “-” sign is used for time
zones in the Western Hemisphere (North and South
America). So for Pacific Standard Time (PST) you would
enter -08:00. Press ENTER to confirm.
6. Enter the date in the format mm/dd/yyyy using the
numeric keypad. Press ENTER to confirm your choice.
7. Enter your current local time using the 24 hour time
mode (e.g., 2:00 p.m. = 14:00). Press ENTER to view the
time you entered. If the time is incorrect, press ESC to go
back to the previous screen. If the time is correct, press
ENTER to confirm.
8. When “Daylight Saving?” is displayed, use the scroll keys
to select “Yes” or “No”. “YES” indicates the time entered
in the previous step is Daylight Saving time, while “NO”
indicates the time entered is Standard time. Press the
ENTER key to confirm and proceed to the next step.
9. Now the screen will display “Begin Alignment?” and ask
you to select 1) YES or 2) NO. Press “1” or ENTER to
start the alignment process. Press “2” or ESC to skip the
alignment process.
NOTE: The hand controller LCD’s red illumination will dim
and the keypad backlighting will turn off if idle for 30 sec-
onds. Pressing any key turns the lighting back on.
GoTo Star Alignment
In order for your StarSeeker III GoTo telescope to accurately
locate and point to objects in the sky, it must first be aligned
on known positions (stars) in the sky. With that information, the
mount can create a model of the sky and of the movements of
astronomical objects.
There are two methods for aligning your StarSeeker III tele-
scope, and they are very similar: Brightest Star Alignment and
2-Star Alignment. Both involve identifying and pointing the
telescope to two different bright stars in the night sky. Both

alignment methods provide the same level of precision. The
only difference is that for the Brightest Star alignment, the
hand controller will prompt you to select the first alignment star
from a directional region of the sky and will provide a short list
of the brightest stars in that region. With the 2-Star alignment
procedure the list of eligible stars is not grouped by region of
sky.
For the novice stargazer unfamiliar with the night sky or the
names of brighter stars, some might find the Brightest Star
Alignment to be the easier of the two methods. The 2-Star
method is for users who know the names of at least some
stars in the night sky. To assist you in performing the align-
ment by either method, we have included in Appendix C a set
of star charts with the names of some bright alignment stars
indicated for easy reference.
Note: Before performing any of the alignment methods,
be sure that your finder scope is precisely aligned with
the telescope tube.
To get the most accurate star alignment:
• The two alignment stars you choose should be at least 60
degrees apart. (For reference, your fist held at arm’s length
spans about 10 degrees.)
• The two stars should be roughly at the same altitude.
• Use a high-power eyepiece, such as the 10mm focal length
eyepiece included with the StarSeeker III.
• When centering an alignment star in the eyepiece, always
end the procedure by using the UP and RIGHT direction
keys.
• If there is overshoot when centering an alignment star in
the eyepiece with the UP and RIGHT keys, use the LEFT
or DOWN keys to pull the star back to the edge of the field
of view and then use the RIGHT and UP keys to center the
star again.
Brightest Star Alignment
Aligning the 1st Star
1. Select “Brightest Star” as your Alignment Method. Press
ENTER.
2. The hand controller will prompt you to “Select Region.”
Referring to Figure 13, choose the region that
corresponds with where you see the brightest star in the
sky. There are eight overlapping regions to choose from,
each covers a 90-degree span in azimuth. The direction
you choose will only affect your alignment star selection;
you will still be able to choose objects to view across the
entire sky once the alignment is complete. Referring to
the included compass may be helpful during this process.
The red portion of the pointer points North, so orient the
compass so that the “N” (0 degrees) is directly under the
red tip.
3. After you have selected a region of the sky, the hand
controller will generate a list of the brightest stars in that
region. Only stars or planets brighter than magnitude
1.5 will appear in the list, and only if they are between
10 and 75 degrees in elevation. If none is found meeting
those criteria, the hand controller will display “No object
found in this region.” Press ENTER or ESC and select
another region of sky.
4. Now, use the Scroll keys to scroll through the list of bright
stars. There will only be a few stars, at most, on the list,
and sometimes only one star. The hand controller will
display the name and magnitude of the bright star on the
first line, and its position on the second line (Figure 14).
On the second line, the first number is the star’s azimuth
angle, or E-W coordinate, in degrees, and the second
number is its altitude above the horizon in degrees.
These coordinates provide a simple way to identify the
bright star you have chosen. When you are confident the
hand controller is displaying the name of the bright star
you wish to align on, press ENTER.
5. The mount will NOT slew to the first selected bright star
automatically. Instead, you will use the direction keys to
slew the telescope to the 1st alignment star selected in
the previous step. Center the 1st alignment star in the
field of view of the EZ Finder II first, then center it in the
telescope eyepiece. Press ENTER to proceed to the next
step.
NOTE: You can change the slew speed by pressing the
RATE key, and then select a number between 0 (slowest)
and 9 (fastest). Generally, a slewing rate of 5 or 6 is best
for centering the star in the EZ Finder II, and a rate of 2
