Note: If the recalled User Object is currently below the horizon, the controller will display “Below Horizon!! Try another obj.” and will automatically return to “Recall Object”.

Identifying an Unknown Object

The GoTo hand controller has the ability to identify celestial objects that are unknown to you. To identify an object the telescope is pointing at, simply press the ID button. You can also scroll to “Identify” in the Main Menu and press ENTER to identify the object. The hand controller will then show a list containing the close objects in the M, IC, NGC, and Named Star catalogs and their angular distance from the location where the telescope is pointed. Use the scroll buttons to view this list of objects. Press ESC when finished.

Linking with a Computer

The GoTo hand controller can be connected to a computer via the supplied computer interface cable. Many commercially available planetarium software programs can utilize this func- tion and be used to control the Sirus EQ-G mount. Look for software that is compatible with the Celestron NexStar 5i/8i or NexStar GPS, like Starry Night Pro. The description below will lead you through the procedure on how to connect and discon- nect the Sirius EQ-G to a computer.

1.Align the mount as described previously (see “Alignment”).

2.Connect the supplied computer interface cable to the smaller modular jack (RJ-11) on the hand controller (Figure 10). Connect the other end of the cable to the COM port of your computer.

3.In the planetarium software of your choice, choose “Celestron NexStar 5i” or “Celestron 8/9/11 GPS” for the driver setup and follow the instructions provided by the pro- gram to connect the mount and computer through the hand controller. The mount will be under the full control of your computer once the connection is successfully established.

4.When finished observing, follow the software’s instructions to close the computer connection to the hand controller.

See Appendix C for more information on computer interfacing.

Auto Guiding

For astronomical imaging, the Sirius EQ-G mount has a des- ignated autoguider jack (Figure 11). The pin-outs on the 6 pin modular jack are SBIG compatible and can be used with most autoguiders available. Refer to Figure 15.1 when connecting the autoguider cable to the mount and calibrating the autogu- ider. Autoguiding speed can be adjusted using the “Auto Guide Speed” function in the Setup Menu.

Updating the GoTo Hand Controller’s Firmware

From version 3.0 and up, the GoTo hand controller’s firmware can be updated over the internet. Users can download firm- ware updates from Orion’s website www.OrionTelescopes. com.

System Requirements

-GoTo hand controller version 3.0 or greater

-Windows95 or later

-An available RS-232 COM port on the PC

-Computer interface cable (supplied)

-DC power supply (7.5V to 15V @ 100mA or greater output with 2.1mm tip positive plug)

Preparing the Computer for the Update

1.Create a folder where you will store the files necessary for the update.

2.Go to the website www.OrionTelescopes.com, and access the support page for the Sirius EQ-G mount.

3.Download and save the Firmware Loader program to the folder you have created on your computer. You will need to download this program only once; after it is saved on your computer, only the firmware data file is needed for future updates.

4.Download and save the firmware update date file to the folder you created. The file will be named OrionVxxxxEQ. ssf, where xxxx indicates the version number of the firm- ware.

Updating the GoTo Hand Controller

1.Plug the modular plug end of the computer interface cable into the middle jack in the hand controller (Figure 10). Plug the serial connector end of the cable to the COM port on your PC.

2.Press and hold down the 0 and 8 numerical buttons simul- taneously, then plug the power supply into the hand con- troller’s DC power jack. The hand controller will beep and display “SynScan Update Ver. x.x” on the LCD screen.

3.Run the Firmware Loader program on your computer.

4.Click on the “Browse” box and select the OrionVxxxx.ssf file location where it was saved previously on your com- puter.

5.Click on the “Update” button, and the new firmware will begin loading into the hand controller.The Firmware Loader will show the progress of the update on your computer screen. It will usually take approximately 5 minutes for the new firmware to load into the hand controller. It may take significantly longer if a serial-to-USB adapter is employed on your computer.

6.When the download is complete, the Firmware Loader will display “Update Complete”.

The firmware in the GoTo hand controller has now been updat- ed. You can click on the “HC. Version” button to confirm the new version number of the firmware (and possibly the data-
