Orion 9995 instruction manual Sirius EQ-G GoTo Hand Controller

In order to set the guiding speed of your Sirius EQ-G, use the following button combinations:

• 2x sidereal rate:	Hold the Fast button, then press
	the Up directional button.
• 1.75x sidereal rate:	Hold the Fast button, then press
	the Left directional button.
• 1.5x sidereal rate:	Hold the Fast button, then press
	the Right directional button.
• 1.25x sidereal rate:	Hold the Fast button, then press
	the Down directional button.

Reversing the Directional Buttons

Celestial objects appear to move through the sky differently when viewed through telescopes and/or accessories of dif- ferent designs. For example, if an object viewed through a refractor appears to migrate towards the left-hand side of an eyepiece’s field of view, it will appear to migrate towards the right-hand side of an eyepiece’s field of view in a reflector telescope.

In order to make viewing and tracking objects convenient, regardless of telescope design, the dual-axis controller fea- tures a “reverse” function which reverses the direction of the hand controller’s directional buttons. This way you can match the directional button to the way the object actually moves in the telescope eyepiece.

To reverse the direction of the Left and Right directional but- tons, press and hold the Slow speed button then press the Left directional button. To reverse the direction of the Up and Down directional buttons, press and hold the Slow button then press the Up directional button.

Once you have reversed the directional buttons, the dual-axis controller will save the reversed settings until it they are man- ually changed again. Turning the power off will not affect the directional button setting last entered.

Northern or Southern Hemisphere operation

The dual-axis hand controller is capable of operating in either Northern or Southern Hemisphere viewing locations. The sys- tem is set up for Northern Hemisphere locations by default, so if you are viewing from a Northern Hemisphere location, it is not necessary to make any setting changes.

For the dual-axis controller to properly track celestial objects in the Southern Hemisphere, press and hold the Down direc- tional button and then press the Set button while powering on the mount. Release the Set button after the mount has successfully powered on and the Guide button begins flash- ing. The controller will now operate properly in the Southern Hemisphere. You can switch back to Northern Hemisphere mode by using the same button combination. As long as the controller is operating in Southern Hemisphere mode, the Set button will illuminate.

Power Conservation

In the interest of conserving the amount of power drawn by the

Sirius EQ-G mount, the Dec. motor will enter a “sleep” mode if left idle for a period of 15 seconds. In “sleep” mode, the Dec. motor stops completely and the amount of used power drops by about 40%. To reactivate the Dec. motor, press the Up or Down directional button.

Upgrading your Sirius EQ-G

While the dual-axis hand controller provides many useful functions such as celestial object tracking and motorized motion control, there is a GoTo hand controller for the Sirius EQ-G available from Orion. The features and functions of the GoTo hand controller are explained in the following section. If you are interested in upgrading your Sirius EQ-G to a GoTo system, call our Customer Service department at 800-676- 1343 or visit our website at www.OrionTelescopes.com for more information.

8.The Sirius EQ-G GoTo Hand Controller

The Sirius EQ-G mount equipped with the GoTo hand control- ler provide easy, computerized location of thousands of night sky objects such as planets, nebulae, star clusters, galaxies, and more for viewing through your telescope. The GoTo hand controller and internal dual-axis motors allow you to automati- cally point your telescope at a specific object, or tour the skies with pushbutton simplicity. The user-friendly menu allows automatic slewing to over 13,400 objects. Even inexperienced astronomers will find themselves quickly mastering the vari- ety of features the GoTo hand controller offers in just a few observing sessions.

Attaching the GoTo Hand Controller

The Sirius EQ-G GoTo hand controller comes with two cables; one for usage with the Sirius EQ-G mount, while the other is for use with the Atlas EQ-G mount. After installation, you will have one of these cables left over. Feel free to discard this cable, as it will not be needed.

The hand controller cable for the Sirius EQ-G has modular connectors (RJ-45) on both ends. Plug the modular connector on one end of the cable into the hand controller jack (Figure 10), and plug the modular connector on the other end of the cable into the mount’s controller jack (Figure 11). Push the connectors into the jacks until they click into place.
