•Once centered, an object can be focused by turning one of the knobs of the focusing mechanism (Page 8, Fig 1, 11). Notice that when observing astronomical objects, the field of view begins to slowly drift across the eyepiece field. This motion is caused by the rotation of the Earth on its axis. Objects appear to move through the field more rapidly at higher powers. See TRACKING OBJECTS, Page 23, for detailed information on how you can counteract the drift in the field of view.
Using AudioStar’s GoTo Capabilities
Before you can use AudioStar’s GoTo capabilities, you must first:
•Learn how AudioStar’s keys move through the menus
•Initialize AudioStar
•Place the telescope in either the
•Perform a quick alignment on the night sky using AudioStar’s alignment routine.
Moving Through AudioStar’s Menus
The AudioStar database is organized in levels for quick and easy navigation.
•Press ENTER to go deeper into AudioStar’s menu levels.
•Press MODE to move back toward the top menu level.
•Press the Scroll keys to move up and down through the options available for each level.
•Press the Arrow keys to enter characters, digits and to move the cursor across the display. The Arrow keys are also used to move the telescope in each direction.
•Press the Number keys to enter digits
•Press the Help (?) key (Page 33, Fig 39, 8) to access
Activate the Arrow Keys
AudioStar’s arrow keys allow you to slew (move)
the telescope up, down, right, or left. The following procedure describes how to activate AudioStar’s Arrow keys:
1.After the batteries are installed and AudioStar’s cord is plugged into the HBX port of computer control panel (Page 10, Fig 3, D), a copyright message displays on the AudioStar LCD display (Page 33, Fig 39, 1).
2.If you are using the LX80 for the first time, it will prompt you to select the desired language. Select English by pressing the enter key. You can use the hand controller to move the telescope in each direction and change the slew speeds.
Slew Speeds
AudioStar has nine slew speeds that move the optical tube at rates that are directly proportional to the sidereal rate and have been calculated to accomplish specific functions. Press a Number key (Page 33, Fig 39, 6) to change the slew speed, which is shown for about two seconds on AudioStar’s display.
The nine available speeds are:

Speeds 1, 2 or 3: Best used for fine centering of an object in the field of view of a higher power eyepiece, such as a 12mm or a 9mm eyepiece.
Speeds 4, 5 or 6: Enables centering an object in the field of a
