1. SmarStar®-E Series
Overview
1.1. SmartStar®-E Series
Features
Alt-Azimuth Mount– The Cube™
The SmartStar®-E 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.
Compatible with many OTAs
Most Optical Tube Assembles
(OTAs) with dovetail connection should be
compatible with the SmartStar
AltAzi mount. The payload of a SmartStar
E mount is between 7 to 11 lbs, depending
on OTAs and observing condition. (If you do
not have a dovetail connection -- attach
your OTA using mounting rings and dovetail
available at your local telescope store or the
OTA manufacturer). Contact iOptron for
expert’s advice on compatibility issues.

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.
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 over 5,000 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.

Step 1. Preparing the Tripod
Extend tripod legs to full extension.
Step 2. Attaching the Mount
Attach mount to tripod using the long bolt (#7). Slide tray on
bottom of shaft. Then screw on round black knob (#9).
Step 3a. Installing Batteries (not included)
Note: you may use 8 AA batteries (Step 3) or the AC adaptor
(Step 5) to operate the mount.
Pull the batteries compartment cover (shown) open.
Gently pull the batteries holder (shown next) out of the
compartment to avoid breaking the attached wires.
Step 3b.
Insert 8 AA batteries (not included) according to the diagrams on
the holder. Refer to the diagram on the holder to orient the
batteries properly. Replace the holder back into the batteries
compartment and replace the cover.
For reference: the battery pack fits in with wires on the bottom
right (See arrow in photo). Use only fresh batteries. Using/mixing
old or low batteries may cause error messages.

Step 5. Plug in hand controller and AC adaptor.
Plug hand controller into either one of the two HBX ports on the
mount. Next plug in AC adaptor. (Or use batteries—see step 3).
Turn on power (the red light should go on).
At this point you can begin observing manually. Use the 4 Arrow
keys (▲▼◄►) to rotate the scope Up, Down, Left, and Right.
Use the SPEED key to change the slew rate from the slowest
(2X) to the fastest (MAX).
The other HBX is reserved for accessories, such as external GPS
module, electronic focuser or laser pointer. DO NOT plug non-
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)
Insert the eyepiece: Slide the eyepiece into the open end of the
eyepiece holder. Tighten the thumbscrews to a firm feel only.
Remove the round dust cover lid from the end of telescope.
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 a 25mm eyepiece) to get a wider field of view.
Later on you can change to higher powers.

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

In case you only find the site information in
decimal format, you can convert them into
d:m:s format by times the decimal 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”.
Set time zone
Press ◄ or ► key, move the cursor to the
bottom of the screen to set the time zone
information (add or subtract 60 minutes per

time zone). Enter minutes “ahead of” or
“behind” UT (universal time). The minimum
time difference is 60 minutes.
• New York City is 300 minutes “behind”
UT
• Los Angeles is 480 minutes “behind” UT
• Rome is 60 minutes “ahead of” UT
• Beijing is 480 minutes “ahead of” UT
• Sydney is 600 minutes “ahead of” UT
after the link is established. Only Daylight
Time Saving and Time Zone settings are
needed. However, the local time and site
info also can be manually entered in case of
GPS malfunction or testing the mount
inside. It is always a good idea to do your
home work to get the GPS coordinates
before traveling to a new observation site.
A clear sky outside is needed for GPS to
communicate well with the satellites.
All the time zones in North America are
behind UT, as shown in the following table.
So make sure it shows “behind” instead of
“ahead of” UT.
Time Zone Hours
behind UT
Hawaii -10 600
Alaska -9 540
Pacific -8 480
Mountain -7 420
Central -6 360
Eastern -5 300
To adjust minutes, use the ◄ or ► key to
move the cursor, and the ▲ or ▼ button to
change the numbers. To change the
“behind” or “ahead of” UT, move the cursor
to “ahead of” and using ▲ or ▼ key to
toggle between “behind” and “ahead of”.
When the number is correct, press ENTER
and go back to the previous screen.

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. 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.
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
13
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.
3. Now, objects located with the finderscope
first will be centered in field of view of the
main telescope.
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.
4.3. Turn Off the Mount
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
tracking accuracy. To do so, press MENU
button, scroll down to “Align”, select “One
Star Align” and press ENTER. A list of three
bright object, 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,
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
the MENU button, scroll down to “Park
Telescope” and press ENTER. Turn the
power off.
5. Use SmartStar®-E

6. Maintenance and
Servicing
6.1. Maintenance
The SmartStar® E 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:
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.
6. 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.
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. As with any quality
instrument, lens or mirror surfaces should
be cleaned as infrequently as possible.
Front surface aluminized mirrors, in
particular, should be cleaned only when
absolutely necessary. In all cases avoid
touching any mirror surface. A little dust on
the surface of a mirror or lens causes
negligible loss of performance and should
not be considered reason to clean the
surface. When lens or mirror cleaning does
become necessary, use a camel’s hair
brush or compressed air gently to remove
dust.
3. Organic materials (e.g., fingerprints)
on the 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.
4. 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.
5. If your telescope is not to be used
for an extended period, perhaps for one
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
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:
• Using the battery? Are the batteries
installed correctly? Are the batteries
®
E mount or
21
fresh? How long have they been used?
(frequent slew and GOTO will deplete
battery power very quickly)
• Using AC or DC adapter? Check the
plugs to the mount and to the power
outlet.
• 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.
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.
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.
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.
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
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:
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 upport@ioptron.com.

A. iOptron warrants your telescope, mount, or controller to be free from defects in materials and workmanship for one year. iOptron
will repair or replace such product or part which, upon inspection by iOptron, is found to be defective in materials or workmanship.
As a condition to the obligation of iOptron to repair or replace such product, the product must be returned to iOptron together with
proof-of-purchase satisfactory to iOptron.
B. The Proper Return Authorization Number must be obtained from iOptron in advance of return. Call iOptron at 1.866.399.4587 to
receive the number to be displayed on the outside of your shipping container.
All returns must be accompanied by a written statement stating the name, address, and daytime telephone number of the owner,
together with a brief description of any claimed defects. Parts or product for which replacement is made shall become the property
of iOptron.
The customer shall be responsible for all costs of transportation and insurance, both to and from the factory of iOptron, and shall be
required to prepay such costs.
iOptron shall use reasonable efforts to repair or replace any telescope, mount, or controller covered by this warranty within thirty
days of receipt. In the event repair or replacement shall require more than thirty days, iOptron shall notify the customer accordingly.
iOptron reserves the right to replace any product which has been discontinued from its product line with a new product of
comparable value and function.
This warranty shall be void and of no force of effect in the event a covered product has been modified in design or function, or
subjected to abuse, misuse, mishandling or unauthorized repair. Further, product malfunction or deterioration due to normal wear is
not covered by this warranty.
IOPTRON DISCLAIMS ANY WARRANTIES, EXPRESS OR IMPLIED, WHETHER OF MERCHANTABILITY OF FITNESS FOR A
PARTICULAR USE, EXCEPT AS EXPRESSLY SET FORTH HERE. THE SOLE OBLIGATION OF IOPTRON UNDER THIS
LIMITED WARRANTY SHALL BE TO REPAIR OR REPLACE THE COVERED PRODUCT, IN ACCORDANCE WITH THE TERMS
SET FORTH HERE. IOPTRON EXPRESSLY DISCLAIMS ANY LOST PROFITS, GENERAL, SPECIAL, INDIRECT OR

OR INABILITY TO USE ANY IOPTRON PRODUCT. ANY WARRANTIES WHICH ARE IMPLIED AND WHICH CANNOT BE
DISCLAIMED SHALL BE LIMITED IN DURATION TO A TERM OF TWO YEARS FROM THE DATE OF ORIGINAL RETAIL
PURCHASE.
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitation on how long an implied
warranty lasts, so the above limitations and exclusions may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
iOptron reserves the right to modify or discontinue, without prior notice to you, any model or style telescope.
