1. AstroBoy® Overview

1.1. AstroBoy® Features

iOptron’s Astroboy® portable telescope is easy to use and easy to carry! Just click and it
finds stars for you. Simply select a star or planet and the built-in computer moves the telescope
for you! Plus, it stays on target as the earth rotates. Functions in both celestial and land modes
for watching stars, birds, or landscapes. Take it with you camping, school, anywhere. It sits on a
desk or can be attached to a tripod.

Alt-Azimuth Mount

The AstroBoy® refractor telescope comes with our Alt-Azimuth Mount. This compact
mount design is probably the most functional and flexible unit on the market. Both axis motors
are built into a small single unit with optical encoders which provides accurate GOTO and
tracking. The proprietary GoToNova
can point your telescope to ANYWHERE above the horizon. With an optional DC adaptor, you
can plug your telescope mount into your car if you’re camping or at any remote location.

The easy to understand controller on the market

®

technology ensures there are no “dead spots” – so you

The GoToNova® hand controller is much easier to use than other similar products. The
hand controller is more intuitive with menu categories well 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.

GoToNova® Computerized Control System

The revolutionary GoToNova® computerized control system is by far the most
technologically advanced automated tracking system available on the market today. With a
database of more than 4,000 celestial objects, including all of the most famous galaxies,

4. Getting Started

You may start observing land and astronomical objects using GoToNova’s arrow keys.

After the telescope was assembled (referring to Section 2. Telescope Assembly), flip the
I/O switch on the telescope mount to turn on the mount. Use ►,◄,▼ or ▲ buttons to point the
telescope to the desired object. Use the SPEED key to change the slewing speed.

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. Set the Telescope to PARK POSITION

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) Loosen the altitude clutch; point the
telescope tube directly up at the zenith, as shown in
Figure 3 left. Tighten the clutch.

(2) Position the mount so that the “N-S” mark
is aligned with the earth’s magnetic north and south
poles, as shown in Figure 3 right. A compass may
be needed.

(3) Level the mount using the bubble on the mount base by adjusting the height of the
mount base or tripod legs.

stored in the hand controller memory.

You may also get into this setup procedure by pressing MENU button from the main

menu, scrolling down and selecting “Set Up Controller,” then selecting “Set Up Time and Site”.

4.3. Using Your Telescope

4.3.1. Getting Familiar with Your Telescope

Always practice your telescope during the daytime to get familiar with the operation.

Eyepiece and diagonal:

1. A 20 mm eyepiece is included with your AstroBoy telescope. If you have multiple
eyepieces, always begin viewing with the lowest power eyepiece. (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.

For example, if a 60mm diameter refractor telescope has a focal length of 360mm, when

a 10 mm eyepiece is used, the magnification will be:

360mm ÷ 10mm = 36X (magnification)

2. The AstroBoy telescope comes with 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 focuser(6) clockwise.

2. While looking through selected eyepiece, slowly retract focusing tube by turning
focuser counterclockwise until object comes into focus.

Electronic Eyepiece:

If your telescope equipped with an electronic eyepiece, such as #8429 (an iOptron
iE1300 electronic eyepiece), refer to the electronic eyepiece manual for the operation. An
electronic eyepiece works just as a short focal length (few mm) eyepiece. Therefore, you need
to start the observation with the longer focal length eyepiece. In most cases, directly replace an
optical eyepiece with an electronic eyepiece will not bring an image onto the computer screen
immediately. Fine focusing is needed. You should practice in daytime to get familiar with your
setup.

4.3.2. 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 start
slew to the general direction where the Moon should be. After the mount stops slewing, it will
automatically begin to track. If the Moon is located inside the filed of view (FOV) of your
eyepiece but not centered, use the arrow keys to center the Moon in your eyepiece. Press the
SPEED button to change the adjusting speed.

If the Moon is not located in the FOV of the eyepiece once the telescope stops slewing,
you may push the telescope mount (not the base or tripod) in the azimuth direction and altitude
direction (by losing the altitude lock) to put the Moon in the FOV. Retighten the altitude lock and
using the arrow keys to center the Moon the eyepiece. In most cases, manual move is needed
only in the azimuth.

4.3.3. 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” which is equally good as one-star
alignment. 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. Now the system is aligned and ready to goto
other stars.

4.4. Turn Off the Mount

When finishing observing, always move the mount to Park Position. If the mount is not
moved afterwards, 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.

6. Maintenance and Servicing

6.1. Maintenance

The AstroBoy® 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 any 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.

22

6.3. Troubleshooting

The following suggestions may be helpful with operation of the AstroBoy 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.

(3) Press the SPEED button to change the slew speed to MAX.

(4) Check the power source, which include:

• 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)

• 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.

(5) If the telescope does not respond to commands, set the power switch to OFF and

then back to ON.

(6) 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.

The Moon (or Star) is high on the sky, why the hand controller says it will rise in certain
hours?

The site information setting, such as minutes behind UT (in US), or DST setting is
wrong. Please go to “Set Up Controller” submenu to double check.

Cannot seem to focus (No image appears in the eyepiece):

(1) Confirm that the dust cap has been removed from the telescope.
(2) Fully extending the telescope tube by tuning the focuser clockwise first. Then turn

the focuser slowly counterclockwise to bring the object to focus.

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.

The telescope does not GOTO the right object, or the alignment is always wrong:

(1) Leveling (very important).
(2) Site information (minutes ahead of or behind UT, DST).
(3) Check the power source.

23

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.

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
or email, avoiding return of the telescope to the factory.

It is strongly suggested that to send your technical questions to [e-mail].

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.

warranty lasts, so the above limitations and exclusions may not apply to you.
