The smaller modular jack on the hand controller (Figure 10) is used for RS-232 communications between the Sirius EQ-G mount and a computer equipped with astronomy software like Starry Night Pro (see “Linking with a Computer”). The 12V DC power jack on the hand controller allows independent use of the GoTo hand controller for users who wish to browse the object database without connecting to the telescope mount (Figure 10). The power jack is also used when updating the firmware in the hand controller (see “Updating the GoTo Hand Controller’s Firmware”).

The included GoTo hand controller bracket attaches to the built-in notch in the tripod center support tray. To install the hand controller bracket, simply line up the tab on the back of the bracket with the notch in the tripod center support tray and slide the bracket forward until it clicks into place (Figure 12). You now have a place to put the GoTo hand controller while you are viewing.

You can reduce the chances of getting your hand controller cable tangled during use by installing the included wire clip. The clip also prevents mechanical strain on the hand control- ler cable when it is in use. The wire clip is adhesive backed for easy attachment to any convenient location on the mount.

table rechargeable battery, like the Dynamo or Dynamo Pro available from Orion.

If you are using a portable battery like the Orion Dynamo, use the 12V DC power cable supplied with your mount (male ciga- rette lighter plug on one end, standard 12V DC power plug on other end) to connect the battery to the 12V DC power jack on the mount (Figure 11). Make sure the Dynamo’s power switch is in the “on” position after connecting. Then, to turn the mount (and GoTo hand controller) on, simply press the power switch on the mount so it is in the “on” position.

Note: The power indicator LED on the mount (near the power switch) will begin to flash when the battery power is low. When the battery power is extremely low, the LED will flash rapidly. Recharge or replace the battery as needed.

Powering the Sirius EQ-G Mount

The Sirius EQ-G should be powered by an 11V to 15V DC power supply (tip positive) capable of producing continuous current of a minimum 2 amps. We recommend using a por-

The ENTER button is used to select the functions and sub- menus in the menu tree, and to confirm certain functional operations.

The SETUP button is a “hot key” that takes you to the Setup Menu.
