1. AstroBoy®-70e 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® technology ensures there are no “dead spots” – so you 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

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, nebulae, star clusters, not to mention the planets, you’ll be able to enjoy star gazing with the simple push of a button.

Megapixel electronic eyepiece for video and image capture

With a 1.3 megapixel camera, you can experience astro-video and astrophotography for yourself! The iOptron electronic eyepiece allows you to view real-time images from your telescope on a computer screen. It transmits live video images of the Moon, Sun, planets and terrestrial objects through a USB cable to your computer. Images can be recorded for later playback or frame imaging.

2. Telescope Assembly

Step 1. Preparing the Tripod

Unlock the tripod leg locks.

Extend tripod legs.

Lock the leg locks afterwards.

Step 1a.

Pull tripod legs apart to a fully opened position.

Tighten the center tripod lock knob to a firm feel to secure the tripod legs.

Caution: Make sure you loosen this lock knob before collapsing the tripod to store away.

Step 2. Attach the mount

Attach mount to tripod by aligning base of mount onto screw on top of tripod and then hand tightening until secure.

Step 3. Install Batteries

Lift the battery cover. Carefully pull out the battery holder from the compartment. Be sure not to accidentally disconnect the wires.

 

Step 3a.

 

Insert 6 AA batteries (not included) in the holder. Refer to the

 

diagram on the holder to orient the batteries properly. Replace

 

the holder back into the battery compartment and replace the lid.

 

Use only fresh batteries. Using old or low batteries may cause

 

error messages.

 

An optional AC adapter and 12V car plug cable are also

 

available for purchase at www.iOptron.com.

Tapered dovetail

Step 4. Attach the telescope

 

Slide the telescope into the dovetail slot on mount along the

 

arrow direction on the slot and secure the telescope using

 

dovetail lock knob (#2). Note that the dovetail is tapered and

 

slides in one direction only (see arrow in photo). Don’t force the

 

telescope into the dovetail slot!

6

Step 5. Attaching Optics

 

Insert 45º diagonal: Insert diagonal (#7) into the eyepiece side

 

of the telescope. Tighten the thumbscrews to a firm feel only.

 

Insert the eyepiece: Remove the supplied 25mm eyepiece (#8)

 

from its container and slide it into the open end of the diagonal.

45º diagonal (#7)

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

Eyepiece (#8)

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 25mm eyepiece) to get a wider field of

 

view. Later on you can change to higher powers. (Eyepieces of

Focus knob (#6)

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 the HBX port on the mount. The hand controller can attach magnetically to the mount arm.

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 is needed.

setting if everything remains unchanged. The daylight saving, time zone and site info will be 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.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. 500mm ÷ 25mm = 20X (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 focuser.

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

Electronic Eyepiece:

AstroBoy-70e comes with a plug and play electronic eyepiece, iE1300 1.3 megapixel CMOS camera. 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.

12

If the Moon is not located inside the filed of view (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. In most cases, manual move is needed only in the azimuth.

Then 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. You may press the SPEED button to change the adjusting speed.

If the Moon is located inside the FOV of your eyepiece but not centered, follow the instruction above to sync it to the center of the FOV.

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 readies to go to other stars.

4.4. Turn Off the Mount

Press the ON/OFF button to turn off the mount.
