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

All G-series telescopes come standard with a 32-channel GPS module for fully automated operation. Simply turn on the GOTONOVATM Hand Controller and the GPS module will automatically synchronize your telescope location and time with the GOTONOVATM computerized control system. View celestial objects without having to manually punch in the date, time, latitude or longitude.

GOTONOVATM Computerized Control

System

The revolutionary GOTONOVATM computerized control system is by far the

4

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

Most Optical Tube Assembles (OTAs) with dovetail connection should be compatible with the SmartStar®-G GOTO AltAzi mount. The payload of a SmartStar®-G 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.

USB Port

The 8402 hand controller comes with a USB port that tremendously expands the functionalities of the already powerful system. With the USB2COM driver installed, 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.

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.

Optional AC Adapter and Car Charger accessories are available at www.ioptron.com

Step 4. Attaching Telescope

Dovetail Attach telescope to mount using the dovetail lock knob (#2).

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

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

4. Getting Started

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:

2) Up

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 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.

A clear sky outside is needed for GPS to communicate well with the satellites.

Press ◄ or ► key, move the cursor to the line below time info to set the time zone information (add or subtract 60 minutes per time zone). Enter minutes “ahead of” or “behind” UT (universal time).

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

All the time zones in North America are behind UT (universal time), as shown in the following table. So make sure it shows “behind” instead of “ahead of” UT.

For other parts of the world, you can find out your “time zone” information from internet, such as http://www.timeanddate.com/worldclock/.

DO NOT COUNT DAYLIGHT SAVING TIME.

To set daylight saving time, use the ◄ or ► key to move the cursor to the bottom of the screen, use ▲ or ▼ button to toggle the Daylight Time Saving between X, which means “No” and √, which means (Yes).

When the number is correct, press ENTER and go to “Setup Site Info” screen:
