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.

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-

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.

Functions of the GoTo Hand Controller

There are four main categories of control buttons on the GoTo

hand controller (Figure 13):

1. Mode buttons

2. Directional buttons

3. Scroll buttons

4. Dual Purpose buttons

Mode Buttons

The three mode buttons are located at the top of the con-

troller, directly below the LCD screen. They include the ESC,

ENTER, and SETUP buttons.

The ESC button is used to escape from a certain command or

go back a level in the menu tree.

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.

Directional Buttons

The directional buttons allow the user to have complete motion
