1. SmarStar®R-80 Overview
1.1. SmartStar®R-80 Features
Introducing our SmartStar®R-80
computerized GOTO telescope system.
Designed with the latest technology the 80
mm lens is crafted with a fluorite based, low
dispersion glass that is ground and polished
to exact specifications. The precision design
is excellent for viewing bright stars, planets
and their moons, as well as for bird
watching and other land objects. Two eye
pieces come standard to allow for flexibility
in viewing either a wider field or a single
focused object.
Alt-Azimuth Mount– The Cube™
The SmartStar® R-80 refractor
telescope comes with our patented Alt-
Azimuth Mount, a.k.a. The Cube™. This
compact mount design is one of the most
functional and flexible units on the market.
Sky & Telescope magazine named it “Hot
Product 2008”. Both axis motors are built
into a small single unit with optical encoders
that provide accurate GOTO and tracking.
The mount is universally compatible with all
telescopes using a dove-tail connector plate.
With an optional DC adaptor you can plug
your telescope mount into your car if you’re
camping or at any other remote location.
Easy to understand controller
The GOTONOVATM hand controller
is much easier to use than other similar
products. The hand controller is more
intuitive with menu categories better
organized. It also has a larger LCD screen
with more lines of content compared with
the competition. Using the hand controller
and its large LCD screen you can quickly
set up your telescope and select where you
want to go.
More precise speed control for
viewing objects
The control system also allows you
to slew the telescope at 5 different drive
speeds, keeping the object within the
telescope’s viewfinder for as long as you
wish.
GOTONOVATM Computerized Control
System
The revolutionary GOTONOVATM
computerized control system is by far the
most technologically advanced automated
tracking system available on the market
today. With a database of 10,000+ celestial
objects including all of the more famous
galaxies, nebulae, star clusters— not to
mention the planets—you’ll be able to enjoy
star gazing with the simple push of a button.

Use the focus knob to bring objects into focus. You may need
to turn the focus knob quite a few turns to focus your telescope
for the first time. Always start observing using a lower power
eyepiece (such as the K25mm eyepiece) to get a wider field of
view. Later on you can change to higher powers. (Eyepieces of
higher powers have narrower field of views; it’s more difficult to
locate objects using high-power eyepieces.)
Step 6. Connecting Hand Controller
Plug hand controller into any one of the HBX (handbox) ports on
the mount.
Turn on power. Now you are ready to observe. Use the 4 Arrow

4. Getting Started
In order to experience the full GOTO
capability of GOTONOVA technology it is
important to set up the mount correctly
before observation.
4.1. Level and Align the Mount
4.1.1. Level the Mount.
Leveling is critical for good GOTO and
tracking accuracy.
Level the mount by
observing the
bubble (shown) on
the base of the
mount by adjusting
the tripod legs.
The bubble should
be in the center of
the circle. It is also recommended to use
additional levelers (such as a torpedo
leveler) to assure precise leveling. Turn the
mount around by pressing ►or ◄button to
make sure it is always leveled during
movement.
4.1.2. Initial Positions
Each time the mount is turned on the default
position is Park Position, (i.e.,its altitude is
90º0.0’ and azimuth is 180º0.0’) which
means the “SOUTH” mark is pointing to
south and the telescope is pointing straight
up at the zenith. To set the Park Position
you can:
1. Align the mount to south by moving the
mount so that the South mark faces south.
An additional compass is needed. Unlock
the altitude lock (#4) and rotate the
telescope to point straight up at the Zenith.
A torpedo level may help. Make sure the
mount is leveled. Then turn the mount
power on.
or
2. Turn the mount power on. Press the
SPEED button to select a slew speed (MAX
for fast slew and 2X for fine tuning). Turn
the SOUTH mark pointing to south using ►
or ◄button. An additional compass is
needed. Rotate the telescope to point to
zenith using the ▲or ▼buttons. A torpedo
level may help. Then turn the mount power
off and turn it on. Or you can press MENU.
Scroll down to “Set Telescope Coord.”
Press ENTER. The default number is “Alt:
90º00.0’ and Azi: 180º00.0’”. Press ENTER
to complete the initialization.
4.2. Setting Up the Mount
For a SmartStar®telescope equipped with a
GPS receiver, the local time, longitude and
latitude information will be received from
satellites after a link is established. For units
without a GPS receiver this information can
be entered manually. Regardless, manual
input is still needed for the time zone and
Daylight Time Saving settings for all
models.
A clear sky outside is needed for GPS to
communicate well with the satellites.
4.2.1. Time and Site Set Up
This is critical to ensure the telescope will
point to the right direction.
Press MENU button. From the main menu
scroll down and select “Set Up Controller”

DO NOT COUNT DAYLIGHT SAVING
TIME.
If your mount is equipped with a GPS
receiver only Daylight Time Saving and
Time Zone settings are needed. However,
the local time and site info can still be
manually entered (in case the GPS signal is
too weak from clouds or buildings). It is
always recommended to get the GPS
coordinates before traveling to a new
observation site.
4.2.2. Using your telescope
Selecting an Eyepiece:
1. Always begin viewing with the lowest
power eyepiece. (Note: a 25 mm focal
length eyepiece has a lower power than a
10 mm one.) A formula can be used to
determine the power of each eyepiece:
Telescope focal length divided by eyepiece
focal length equals magnification. Ex.
400mm ÷ 25mm = 16X (magnification)
2. Included with this telescope is a 45°
Erecting Diagonal Prism. The Erecting
Diagonal Prism is used to erect the image
you will see. Astronomical telescopes are
designed in such a way that the image you
see may be UPSIDE DOWN and
REVERSED. This is acceptable for viewing
celestial bodies. However, it will feel strange
when observing a land object or a bird.
Focusing Telescope:
1. After selecting the desired eyepiece aim
the telescope tube at a land-based target at
least 200 yards away (e.g. A telephone pole
or building). Fully extend focusing tube by
turning the focus knob.
2. While looking through selected eyepiece,
slowly retract focusing tube by turning
focusing knob until object comes into focus.
4.2.3. Go to the Moon
After performing these setups, the mount is
ready to GOTO and track objects. The most
common object will be Moon.
Press MENU button, select “Select and
Slew” by press ENTER button. Select
“Planets, Sun, Moon”, and using ▲or ▼
button to select Moon. Press ENTER. The
telescope will automatically slew to the
Moon and lock on. Press BACK key to stop
GOTO. It will automatically begin to track
once it locks on to it. Use the arrow keys to
center the Moon in your eyepiece, if it is not
centered. Press ENTER key to stop the
tracking.
4.2.4. Initial Star Alignment
A simple alignment/synchronization can be
performed to improve the GOTO and
tracking accuracy. To do so, press MENU
button, scroll down to “Align”, select
“Solarsys Align” and press ENTER. The
screen will list Moon, Sun and other planets
for you to select from. Select an object
using ▲or ▼key. Then press ENTER. The
mount will slew to the object. Use ◄►▲
or ▼key to center the object in your
eyepiece. Press SPEED button to change
the slew speed if needed. Then press
ENTER to complete the alignment. Or press
the BACK key to cancel the process.
An alternate way is performing “Sync to
Target”. To do so, press MENU button,
select “Select and Slew” and press ENTER.
Then select a known sky object, such as
Moon from “Planets, Sun, Moon” menu and
press ENTER. The mount will slew to the
Moon. When the mount stopped slewing,
the Moon could be just inside your eyepiece
or way off. Press MENU button and scroll
down the menu to “Sync to Target” and
press ENTER. Follow the instruction, use ◄

13
►▲and ▼keys to move the Moon in the
center of your eyepiece and press ENTER.
4.3. Turn Off the Mount
When finishing observing, always move the
mount to Park Position. If the mount is not
moved, no initial set up is needed when
powered on the next time. To do so, press

5.5.3. Set Azi Work Mode
This function will set the mount azimuth
mode while performing GOTO. There are
two modes for selection:
The “AZI +/- 200 degree” will rotate the
mount between -200º and +200º in azimuth
direction to avoid AC/DC power line
wrapping. However, the mount may take a
longer path to slew to an object. The “AZI
free running mode” will take a shortest path
while rotating along the azimuth direction,
which is best for battery operation. The
default setting is “AZI +/- 200 degree” mode.
5.5.4. Reset All
Reset all settings to factory default data.
5.6. Align
This function is used for align the telescope.
Before star alignment, please make sure the
mount is well leveled. In addition to
“Solarsys Align,” the system also provides
“One Star Align” and “Two Star Align”.
Either one can be selected for telescope
alignment.
5.6.1. Solarsys Align
Press “MENU”, scroll down the menu and
select “Align”. Press ENTER and select
“Solarsys Align”. Select any one of the listed
solar system object as your alignment
target, such as Moon. Press ENTER. If the
Moon is above the horizon, the telescope
will auto slew to it. If the Moon is not in the
center of you eyepiece, use ◄►▲or ▼
key to center the object in your eyepiece.
Press SPEED button to change the slew
speed if needed. Then press ENTER to
complete the alignment.
5.6.2. One Star Align
From the main menu, select “Align”. Select
“One Star Align” and press ENTER. A list of
bright align stars that are above the horizon
is computed based on your local time and
location. These stars are listed
alphabetically. Use ▲or ▼button to select
a star and press ENTER. The mount will
slew to it automatically. Use ◄►▲or ▼
key to center the object in your eyepiece.
Press SPEED button to change the slew
speed if needed. Then press ENTER to
complete the alignment. Or press the BACK
key to cancel the process.
If you have a very good initial setup,
one star alignment should be sufficient for
good GOTO accuracy. To increase the
accuracy you may choose to do two star
alignment.
5.6.3. Two Star Alignment
Two star alignment will increase the GOTO
accuracy of the mount. It is suggested to do
two star alignment after one star alignment.

6. Maintenance and
Servicing
6.1. Maintenance
The SmartStar®R-80 telescope is a
precision optical instrument designed to
yield a lifetime of rewarding applications.
Given the care and respect due any
precision instrument, your telescope will
rarely require factory servicing or
maintenance. Maintenance guidelines
include:
1. Using wet cloth to clean the mount
and hand controller. Do not use the solvent.
2. Leave the dust cap on while not
operating the telescope. Avoid cleaning the
telescope’s optics. A little dust on the front
surface of the telescope’s correcting lens
causes virtually no degradation of image
quality and should not be considered a
reason to clean the lens.
3. When absolutely necessary, dust on
the front lens should be removed with gentle
strokes of a camel hair brush, a soft glass
clean cloth or blown off with an ear syringe
(available at any pharmacy). Do not use a
commercial photographic lens cleaner.
4. Organic materials (e.g., fingerprints)
on the front lens may be removed with a
solution of 3 parts distilled water to 1 part
isopropyl alcohol. Use soft, white facial
tissues or cotton balls and make short,
gentle strokes. Change tissues often. Do
not use scented, colored, or lotioned tissues
as damage could result to the optics.
5. If your telescope is used outdoors on
a humid night, telescope surfaces may
accumulate water condensation. While such
condensation does not normally cause any
damage to the telescope, it is
recommended that wait the entire telescope
be dried before being packed away. Do not
wipe any of the optical surfaces. In addition,
the dust cap should not be placed back on
to the optical tube until the telescope is
thoroughly dry.
6. If your telescope is not to be used
for an extended period, perhaps for one
month or more, it is advisable to remove the
batteries from battery holder, if they are
installed. Batteries left installed for
prolonged periods may leak, causing
damage to the telescope’s electronic
circuitry.
7. Do not leave your telescope
outdoors on a warm day or inside a sealed
car for an extended period of time.
Excessive ambient temperatures can
damage the telescope’s internal lubrication
and electronic circuitry.
6.2. Storage and Transport
When not in use, store the telescope in a
cool, dry place. Do not expose the
instrument to excessive heat or moisture. It
is best to store the telescope in its original
box with the altitude lock knob unlocked. If
shipping the telescope, use the original box
and packing material to protect the
telescope during shipment.
When transporting the telescope, take care
not to bump or drop the instrument; this type
of abuse can damage the optics or affect
the GOTO tracking accuracy.
6.3. Troubleshooting
The following suggestions may be helpful
with operation of the SmartStar R-80.
The power indicator light on the mount
does not come on or there is no
response when pressing hand
controller’s arrow keys:
(1) Verify that the power switch on the
mount is in the ON position.
(2) Verify that the hand controller cord is
firmly connected to the HBX port on
