1. SmarStar®-G Series
Overview
1.1. SmartStar®-G Series
Features
Alt-Azimuth Mount– The Cube™
The SmartStar®-G series come with our
patented Alt-Azimuth (AltAzi) mount, a.k.a.
The Cube™. This compact mount design is
probably the most functional and flexible
unit on the market. It was named “Hot
Product 2008” by Sky and Telescope. Both
axis motors are built into a small single unit
with optical encoders which provides
accurate GOTO and tracking. The mount is
universally compatible with all telescopes
using a dove-tail connection. In addition,
there are no “dead spots” – so you can point
your telescope to ANYWHERE above the
horizon, whereas, other mounts block the
telescope tube at certain points of rotation.
This mount also comes standard with AC
connection. An optional DC adaptor is
available so you can plug your telescope
mount into your car if you’re camping or at
any remote location.
32-Channel GPS Module
most technologically advanced automated
tracking system available on the market
today. With a database over 50,000
celestial objects, including all of the most
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.
The easy to understand controller on
the market
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 easy-to-use hand controller and
its large LCD screen, you can easily 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.
Compatible with many OTAs
All G-series telescopes come standard with
a 32-channel GPS module for fully
automated operation. Simply turn on the
GOTONOVA
GPS module will automatically synchronize
your telescope location and time with the
GOTONOVA
system. View celestial objects without
having to manually punch in the date, time,
latitude or longitude.

the USB port works as an RS232 serial port.
It supports firmware upgrades and computer
control. With ASCOM protocol, you can
control your telescope with most ASCOM
compatible software. This enables you to
utilize the CPU, large screen, and disk
space of your PC/laptop. With a wide
selection of software, your star gazing
experience will never be the same again.

iOptron accessories into the unit to avoid damaging the
mount or accessories.
Insert 45º diagonal: Insert the diagonal into the eyepiece side of
the telescope. Tighten the thumbscrews to a firm feel only.
Insert the eyepiece: Slide the eyepiece into the open end of the
diagonal. Tighten the thumbscrews to a firm feel only. Remove
the dust cover from the other end of optical tube assembly.
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 low power eyepiece
(such as a 25mm eyepiece) to get a nice wide field of view. Later
you can change to high power if so desired. Higher powered
eyepieces have a much narrower field of view. So it’s more
difficult to initially locate objects using higher powered eyepieces.
Attach the red dot finder scope to the telescope tube (#1):
First remove the two washers on the tube. Then place the finder
scope onto the two bolts and re-attach the washers securely. The
finder scope should face towards the open end of the tube (see
arrow in diagram).
Turn on the beam using the switch on the side. (note: you may
need to remove the plastic insulation placed next to the battery
underneath)
Install Diagonal by screwing it onto the back end of the scope.
You can adjust the position of the diagonal by loosening the free-
spinning threader on the diagonal.

4. Getting Started
sure the mount is leveled. Then turn the
mount power on.
In order to experience the full GOTO
capability of GOTONOVA technology, it is
very 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 a good GOTO and
tracking accuracy.
Level the mount by observing the bubble
(shown) on the base of the mount by
adjusting 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.
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 do one of the following:
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 may be needed.
Rotate the telescope point to the zenith
using ▲ or ▼ button. 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
A SmartStar-G
is equipped with
a GPS receiver,
which will
receive the local
time, longitude
and latitude
information from
a satellite after the link is established.
However, manual input is still needed for
time zone and Daylight Saving setting.
2) Up
1) South
1. Align the mount to south by turning the
mount so that the South mark facing

If for any reason your GPS can’t pick up a
signal you can manually enter the GPS
coordinates. Press ◄ or ► key to move the
cursor and using ▲ or ▼ key to toggle
between “W” and “E”, “N” and “S”, or to
change the numbers. It is always a good
idea to do your home work to get the GPS
coordinates before traveling to a new
observation site.
The site coordinates information can be
found from internet, such as GPSVisualizer
(http://www.gpsvisualizer.com/geocode
entering the city name or address. In case
you only find the site information in decimal
format you can convert them into d:m:s
format by multiplying the decimal numbers
by 60. For example, N47.53 can be
changed to N47º31'48”: 47.53º = 47º
+0.53º, 0.53º=0.53x60'=31.8',
0.8'=0.8x60"=48". Therefore,
47.53º=47º31'48" or 47d31m48s. Same as
N47º31.8’: 31.8’=31’+0.8’, 0.8’=0.8x60”=48”.
), by
4.2.2. Using your telescope
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.
Aligning Finderscope:
1. Look through main telescope tube and
establish a well-defined target (see focusing
telescope section). Tighten all lock knobs
(Declination, Latitude, Right Ascension,
Horizontal Axis) so that telescope’s aim is
not disturbed.
2. Turn on the red dot finder and look
through the finder window. Adjust the red
dot alignment screws to center the red dot
on the object.
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). The
rule of thumb is that the magnification
should not be too much larger than the OTA
aperture, otherwise view and color distortion
may occur.
2. A 45° Erecting Diagonal Prism is included
in the R80 or MC90 telescope. 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 perfect for viewing
celestial bodies. However, it will feel strange
when observing a land object or a bird.
3. Now, objects located with the finderscope
first will be centered in field of view of the
main telescope.
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 the 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. 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 BACK key to stop
GOTO during the slew. 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
14
tracking accuracy. To do so, press MENU
button, scroll down to “Align”, select “Easy
One Star Align” and press ENTER. A list of
three bright objects, such as Moon, Venus,
and other stars, will be displayed for you to
select from. Select an object using ▲ or ▼
key. Then press ENTER. 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 ◄
► ▲ and ▼ keys to move the Moon in the
center of your eyepiece and press ENTER.

6. Maintenance and
Servicing
6.1. Maintenance
The SmartStar® G mount or telescope is a
precision 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
22
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
Cannot seem to focus (No image
appears in the eyepiece):
1. Confirm that the dust cap has been
removed from the telescope.
2. Keep turning the focus knob. Your
telescope has a fine focusing
mechanism which allows you to focus
an image very precisely. However, this
means that you may have to rotate the
focus knob 20 to 40 complete turns to
achieve focus, particularly the first time
you use your telescope. After that, fewer
turns will be needed.
The following suggestions may be helpful
with operation of the SmartStar
telescope.
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 the
mount, or switch the cord to the other
HBX port.
3. Check the power source, which include:
o Using the battery? Are the batteries
installed correctly? Are the
batteries fresh? How long have
they been used? (frequent slew
and GOTO will deplete battery
power very quickly)
o Using AC or DC adapter? Check the
plugs to the mount and to the
power outlet.
o Using extension cord? Make sure
the cord is in good condition.
Power drop along the extension
cord was known to cause the
problem. Also check all the plugs
and connections.
1. If the telescope does not respond to
commands, set the power switch to OFF
and then back to ON.
2. If the telescope does not slew after
power is applied or if the motor quits or
stalls, verify that there are no physical
obstructions that would impede
telescope movement.
®
E mount or
Images through the eyepiece appear
unfocused or distorted:
1. The magnification used may be too high
for the seeing conditions. Back off to a
lower power eyepiece.
2. If inside a warm house or building, move
outside. Interior air conditions may
distort terrestrial (land) or celestial
images, making it difficult, if not
impossible, to obtain a sharp focus. For
optimal viewing, use the telescope
outside in the open air instead of
observing through an open or closed
window or screen.
3. If viewing a land object on a warm day,
heat waves distort the image.
4. The optics within the telescope need
time to adjust to the outside ambient
temperature to provide the sharpest
image. To "cool down" the optics, set
the telescope outside for 10 to 15
minutes before observing begins.
Error Message “Warning! Motor driver
overloaded.”
1. Check the hand controller cord. Unplug
it and re-plug into, or plug it into another
HBX port.
2. Check the power source.
The telescope does not GOTO the right
object, or the alignment is always wrong:
23
1. Leveling (very important).
2. Site information (minutes ahead or
behind UT, DST).
3. Check the power source.
6.4. iOptron Customer Service
If you have a question concerning your
telescope, contact the iOptron Customer
Service Department. Customer Service
hours are 9:00 AM to 5:00 PM, Easter Time,
Monday through Friday. In the unlikely
event that the telescope requires factory
servicing or repairs, write or call the iOptron
Customer Service Department first, before
returning the telescope to the factory, giving
full particulars as to the nature of the
problem, as well as your name, address,
and daytime telephone number. The great
majority of servicing issues can be resolved
by telephone, avoiding return of the
telescope to the factory.
It is also strongly suggested to send your
technical questions to support@ioptron.com

Appendix D. Set Up USB-PC Connection
Before a computer being used to control the mount or update the firmware, a connection
between PC and 8402G Hand Controller has to be established. There are two versions of 8402
HCs, namely 8402G and 8402A. The USB2COM chipsets used in these two HCs are different.
To identify your HC’s version, please read the initial LCD screen when the mount is turned on.
If it is an 8402G Hand Controller, the LCD screen shows following when it is turned on:
TM
GOTONOVA
8402G V071022W
www.iOptron.com
1. Install PL-2303 (usb2com) driver
Download USB to COM driver for 8402G hand controller from iOptron website and double click
on the compressed file:
Double click on it, and you will see:
34
Click “Next”.
When finished installation, click “Finish”
2. Plug the USB cable into a USB port on your PC, plug the other end of the USB
cable to hand controller. Turn the mount power on.
35
3. Install the Hardware
The computer will find a new hardware and install the driver automatically.
Now you computer should be ready for Firmware Upgrading, computer communication with the
mount via ASCOM platform and planetarium software applications. However, you need to find
assigned COM port number for the USB connection. To do so, right click “My Computer”, and
click “Properties”
Click “Hardware”, click “Device Manager”
36
Double click on “Ports (COM & LPT)”, find out the COM number and write it down (in the
following figure, it is COM4)
37
Appendix E. Firmware Upgrade
1. Download and install Firmware Downloader from iOptron Website
2. Double click and open “iOptron Downloader”
On the interface, select appropriate port using pull-down menu (in this case, COM4):
38
Click “Open Data File”, and select appropriate “.bin” file that matches your hand controller.
and click “Open”. Select “Main Program” ONLY in Update Type.
Click “Start Download”
It shows “Please reset GOTONOVA[GOTOSTAR], waiting for connection…”
On the hand controller, press “MENU”, and using ▼▲ scroll to select “Set up controller”, press
“ENTER”, then select “Upgrade firmware”, press “ENTER” and the upgrade starts.
39
Now the upgrade is finished.
Typical Errors:
1. Invalid Port Number: in Device Manager, make sure you have the correct COM port
number for “Prolific USB-to-Serial Comm Port.”
2. Wrong “.bin” file: make sure you have the correct “.bin” file for firmware upgrade.
3. Wrong downloader, you should use iOptron Downloader instead of the Flash
Downloader.
4. Use PL-2303 driver provided by iOptron. The newest version from Prolific may not work
properly for iOptron’s hand controller.

Appendix F. Use a PC to Control an iOptron Mount
In general you need the followings to use a PC to control a SmartStar-G mount,
1. Download USB2COM driver (PL-2303, zip file for 8402G)
http://www.ioptron.com/support.aspx?catalog=28;
2. Install USB2COM and establish the connection between the mount and the PC (see
instruction);
3. ASCOM platform (download from http://ascom-standards.org/);
4. iOptron ASCOM drive (download it from iOptron website,
http://www.ioptron.com/support.aspx?catalog=28) iOptronAscomSetupV1.02.exe; and
5. Planetarium software.
Some company has integrated iOptron’s products into their planetarium software, such
as Voyage and The Sky X Pro. Therefore, an ASCOM plug-in will not be needed. Most
planetarium software can be used to control iOptron’s product via ASCOM.
Some other ASCOM drivers, such as LX200 Generic ASCOM driver and AstroPhysics
GTO driver, are also compatible to SmartStar
®
mount.
