1. Quick guide for ready use

It is recommended that users read all sections of this document carefully to make optimum use of the StarGO system. However, we realize that many users are impatient to use their new systems as soon as possible, especially when good seeing conditions prevail. Therefore this section contains two quick guides so that owners of Avalon mounts and the StarGO control system may make them operational in the shortest possible time. Every step in this section contains a reference to the part of the manual where that operation is detailed later in the manual.

2. System Description and Technical Specifications

The Avalon Mounts are well known for their capability to drive mounted telescopes with extreme precision. This is due to three factors: the first is the precision and strength of CNC machined components; the second is the use of high-torque motors and toothed belts for motion transmission; the third is a proprietary control system, called StarGO, developed and patented by Avalon Instruments. The onboard intelligence of this system is able to provide many types of mounts with the ability to perform all the required operations for easy and accurate visual observations. However, its greatest strength lies in precise control for long exposure astrophotography.

The StarGO Goto Control System is composed of five main components:

1. The StarGO Control Box that can be embedded in the mount as for the Avalon Linear and M-Uno, or in a separate control box for the M-Zero. Thanks to the programmable

Gear Ratio and the special motor kit, the StarGo Control Box is also compatible with many mounts from other manufacturers. It has the ability to provide a smart interface between the mount’s drive motors and the external world. Using internal and user-selected computerized astronomy software applications, it performs all the necessary communications with specific components, including the autoguider, focuser, CCD rotator,

DSRL camera, and other auxiliary devices, using USB connections with Windows and Macintosh computers. Wireless capability, based on Bluetooth (right picture) or Wi-Fi (left picture), is also integrated in the control box unit to interact with intelligent devices such as smartphones, tablets, Android devices as well as Windows and Mac computers. The wireless system (BT or Wi-Fi) must be choosen at time of order.

2. The StarGO Keypad is able to physically command the mounts and perform almost all the most needed operations without the use of a computer or other control device.

3. The StarGO software, entirely written and compiled by Avalon Instruments uses a computer to perform all the setup and management operations, including the control of various external equipment that can be connected to the control box. It is also able to perform all the same operations performed by the StarGO keypad.

_____________________________________________________________________

4. The StarGO-BT application for Android devices allows them to interface with the StarGO control box via Bluetooth connection. With this application the Android devices become perfect smart-device control pads. This application, as well as StarGO, is under continuous development to add new functionalities.!

5. The AvalonStargo ASCOM driver makes possible the interaction between the StarGO Control Box and the vast majority of third party software applications such as Cart du Ciel, Stellarium, etc. In addition, thanks to the compatibility with the LX200 standard, the StarGO can work with almost all other software applications.

The StarGo Goto Control System was designed mainly for the Avalon Instruments M-zero, M-uno and Linear mounts, but thanks to the programmable Gear Ratio and the special motor kit, it also may be easily used with a variety of mounts from other companies.

StarGo’s design follows the most recent technological developments in this field. It consists of a very simple hardware interface which facilitates a wide range of applications such as the management of focusers, filter wheels, autoguiders, DSLR cameras, etc. without the need of frequent modifications to additional devices. At the same time, it retains the ability to be controlled by PCs, smartphones and tablets.

To make these characteristics possible, the StarGo Control System intelligence has been moved to the external software which can be easily updated or modified to work with different operating systems such as Windows, Mac OSX, Android and others.

The logical interactions of the StarGO Control System with all hardware and software devices is reported in the following schematic diagram.

2.2 The StarGO Goto Control System hardware interface

It is supplied with the following items:

1. Main Board and Aluminium case.

2. StarGO control keypad.

3. Keypad connection cable (RJ45 Standard).

4. USB cable.

5. 12-24 VDC power supply with 110-240 VAC and 12 VDC inputs + cigarette

lighter 12V power cable.

6. A USB flash drive containing the StarGO software and other utilities needed for

its setup and operation, as well as the complete documentation, including this

and other manuals.

7. A foam-lined high-impact carrying case for all of the above

The Main Board for the Avalon Instruments Linear and M-uno mounts comes already internally installed from the factory. On the M-zero mount it is mounted externally. The

StarGO control box which comes with the Stand Alone Kit is designed to be installed

externally on mounts of other brands.

The StarGO Control Box is an attractive Aluminium case which contains the StarGO

main control board and has external connections to power the motors and other

devices (item 1 above).

This section describes the StarGO control interface and the related keypad.

Figure 2.1 illustrates the physical interface of the StarGO control box.

The output port Aux1 and Aux 2 can be used to drive motorised device such as focusers other than Baader Steeldrive (for example the Avalon Instrument FOCS), Time Lapse Dolly, etc.

Once the power has been provided to the StarGO, the red LED above the On/Off button will start to blink, indicating that the StarGO is powered but the RA and DEC motors are stopped. This means that the mount is not tracking the sidereal movement. To activate tracking, briefly push either a) the red button (#1) on the StarGO Control Box, or b) one of the directional buttons (W – E – N – S) of the keypad or c) one of the directional buttons of the StarGo GUI main panel on the PC. (see figure 4.1).

To interrupt the tracking movement while still leaving the StarGO powered, hold the red button (#1) down for at least 5 seconds. The red LED will commence blinking once again.

The figure 2.2 illustrates the manual keypad which is connected to the StarGo Control Box at the plug labelled “Keypad” (#8) with the included RJ45 cable.

3. Software Installation

NOTE: In order to avoid software difficulties, especially with more recent operating systems, it may be necessary to run these applications as Administrator. To enable this option, select “Execute this program as Administrator” from the Compatibility window under the Properties tab of the executable files. This can be found within the Programs\Avalon\StarGo folder. To guarantee perfect compatibility it is necessary that all other applications (such as planetarium programs, autoguide, CCD and DSLR management software, plate solving applications, etc.) are also run as administrator.

3.1 StarGo, StarGoLoader application and FTDI driver installation.

To get maximum use of the StarGO system features and to obtain complete mount control, it is necessary to install the applications supplied on the flash drive.

However the mount is able to track objects, both in equatorial and Alt-azimuth configurations, even without a connection to a PC or other device.

The StarGO software is provided with an ASCOM driver, making it controllable with most astronomical applications. During the software installation process, as described below, the Avalon ASCOM driver, the serial-USB FTDI drivers, the StarGO application and its firmware and related update utility are installed.

_____________________________________________________________________

16!

The use of StarGO in an ASCOM environment with the more popular compatible software applications is described in detail in a specific document (StarGO – Third Party Software Use – Instruction Manual).

Note: Before launching StarGO be sure that the ASCOM platform is installed in the PC (http://download.ascom-standards.org/ASCOMPlatform62.exe). If this is not done, the program will abort and the Run-Time error message “429” will be generated. Upon special request Avalon Instrument could supply a version of StarGO not needing the ASCOM platform.

The StarGO software is provided in a USB flash drive. The software installer file, called “Install StarGo_xxx.exe”, is located in the folder "Installer-Tutorial-Software".

The step by step software installation procedure, on a Windows 8 computer, is the following:

1. Launch the “Install StarGo_xxx.exe” application (xxx is the installer version number). The installation language chooser will appear. The “InstallWizard StarGo” windows will appear. Choose the preferred language and than OK:

2. The installation splash screen will appear containing the StarGO GoTo Control System Setup Wizard welcome window. Click Next:

_____________________________________________________________________

17!

3. The welcome window inside the splash screen will be replaced by the License

Agreement window. Select “I accept the agreement” and then “Next”.

4. The next window will allow the creation of a StarGO desktop icon. It is advised to

accept and then press “Next”.

_____________________________________________________________________

18!

5. The next window inside the splash screen will present the summary of the task

selected and proposes to start the installation. Press “Install” button.

6. At the end of the installation process a window will be presented to finish the

installation process, asking to perform additional operations if needed: install The FTDI USB drivers, install the most updated StarGO ASCOM driver and launch the StarGO software at the end of the installation process.

_____________________________________________________________________

19!

NOTE: The FTDI serial-USB drivers must be installed during the first installation. Because they are much more less frequently updated than the StarGO driver, it is not necessary to install them each time.

7. Press “Finish”. In case the FTDI driver installation has been selected the “Device Driver Installation Wizard” will appear.

8. Press “Next”. The windows announcing the correct driver installation will appear. Press “End” to exit. The new drivers are ready for the USB connection.

9. After the FTDI driver installation (if selected) the Avalon ASCOM driver installation wizard will pop up. Press the “Next” button.

10. Accept the License Agreement in the following window and press “Next”. Press “Install” on the subsequent window:

_____________________________________________________________________

21!

11. A final window will inform that the installation process has been successfully completed and propose to view the contained Readme file of the installation.

3.2 Software Updating

The StarGO software and firmware are subject to continual improvement and updating, with additional functions being added all the time. We therefore advise users to frequently consult the Avalon Instruments website Support page to be assured that their StarGo software and firmware are the latest updated versions.

The updating process consists of repeating the installation operations previously described in Software Installation, Section 3.1. Items 4 and 5 related to the serial/USB driver installation need not be performed at this time.

Firmware Warning

_____________________________________________________________________

22!

When a new StarGO software application is first launched and connected, it is possible that a warning message will appear indicating that the existing StarGO firmware within the hardware is obsolete and incompatible with the newly installed software.

Figure 3.1

If this message appears, it will be necessary to update the firmware following the instructions given in Section 7. The file containing the newest firmware to be chosen will be the most recent one among those available in the StarGO folder. When the firmware updating has been completed it is necessary to restart the StarGO application and verify that the “Obsolete StarGO Firmware” warning does not re-appear.

_____________________________________________________________________

23!

4. StarGO program description

4.1 Graphical User Interface (GUI)

When using StarGo with a computer or other device, activate the StarGO GUI by clicking

the icon created on the desktop during the program installation. The user interface appearance is shown in Figure 4.1a.

Figure 4.1a – StarGO Main Panel before connection

To animate the GUI it is necessary to perform the StarGO connection with the hardware. To

do this press the button with the USB icon and the COM port selection window will appear.

Figure 4.1b – COM Port setting

The connection will be established by selecting the correct COM port (normally the port suggested in the Select Com Port menu) and pressing OK. The USB icon will be highlighted

and with the sudden appearance of a blinking red LED, it will signal the correct

connection. The red LED on the GUI has the same functions as the button installed on

_____________________________________________________________________

24!

the StarGO hardware (item #1 of Fig. 2.1). If at the end of the previous session the mount has been correctly parked, the main GUI panel will appear as follows:

Figure 4.1c – Main Panel with the mount parked

If the mount has not been not parked or after the UNPARK button is pressed, the GUI will look like this:

Figure 4.1d - Main Panel with the mount unparked

A quick click on the LED or on one of the directional arrow buttons will activate the sidereal tracking and the LED will remain on (same as the physical LED on the StarGO) obtaining the same result of a brief pressure of the mentioned physical button #11 in the StarGO hardware.

Just as holding the red power button on the StarGo Control Box for longer than 5 seconds will cause tracking to stop, a double click on the LED symbol will have the same effect. The red LED on both StarGO Control Box and the LED software symbol will flash as tracking stops. This action will initiate a warning message and a confirmation to stop the tracking motors.

_____________________________________________________________________

25!

4.2 Parameter setting

Pressing the setup button on the upper right, the GUI extends to show the mount parameter setting panel. As seen in Figure 4.2, this panel contains five tabs for setting different parameter types.

4.2.1 System Panel

The SYSTEM tab allows the selection of the StarGO connection COM port number, as seen in Figure 4.1b and the upload of a newer firmware version. The “Save Screen Position”checkbox selects if the StarGO GUI position on the screen should be saved.

Figure 4.2 – “SYSTEM” Panel

This panel reports also the StarGO software, firmware and ASCOM driver versions as well as the type of mount and the axis mode (equatorial or alt-azimuth).

The timeliness of the given versions of firmware and software is evaluated by the software itself and, in case they are not current, the user is warned and advised to update.

Saving the “Mount Configuration File” containing the mount configuration parameters (this file has the .mcf extension) is done by pressing the Save and Load buttons. The names of the parameter files to be loaded are shown below these buttons. The Configuration Files have the following format:

_____________________________________________________________________

26!

The above figure shows only a few of the mount parameters. The total number of the parameters is normally of several tens. Their values depend on the software version, the mount type and the custom settings. With the StarGO installation several default .mcf files are copied in the StarGO folder, related to the Avalon Instrument mounts and to the StarGO standalone kits available for supported mounts of other brands. Other configuration files may be added by the user, containing different customized setups for the owner’s mount(s), using the described Save button. The most suitable configuration file is uploaded to the StarGO using the Load button.

4.2.2 RA DEC Panel

Pressing the RA-DEC tab opens the panel shown in Figure 4.3 which enables access to the guide settings of the mount.

Figure 4.3 –“RA-DEC” Panel

The “AUTOGUIDE SETTING” frame allows the regulation of the auto-guiding speed, with increments of 0.05x times the sidereal speed. This regulation can be performed independently for the two axes. It has effect for the signal coming from the ST4 port and forthe pulse guiding signals coming from the USB ports. The check box “ST4 Enable” allows to enable/disable the ST4 port.

NOTE: If a ST4 cable is still connected and it is impossible to move the mount, it is strictly necessary to unplug the cable or disable the ST4 using this check box. This malfunction event happens because some CCDs leave the port locked after use, preventing to use other moving speeds then guide.

The “SYSTEM SPEED” frame enables changing the values of moving speed when using the directional buttons of the main panel of the StarGO GUI or the Fn&E / W keys in the keypad.

The available slew speeds are: “Low”, “Medium”, ”Fast” and “Ultra”. The latter requires at least 15 VDC to be supplied to the system.
