Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the Sun. Do
not look through the telescope as it is moving.
Important Note for
Reflecting Telescope
Owners: When you look
through your telescope’s
eyepiece, the image
might look strange at
first.
If you have a reflecting
telescope, objects will
appear upside down and
reversed left-for-right.
This will not make a
difference when
observing astronomical
objects, and in fact, all
Reflecting telescopes
present inverted images
There is no means of
correcting the image.
This is normal.
ON position.
4. AudioStar is activated and a copyright message displays briefly, followed by a short beep.
Then AudioStar takes a few moments to start up the system.
5. The Arrow keys are now activated. Press the Arrow keys (5, Fig. 3) to slew (move) the
telescope up, down, right, or left.
6. Press a NUMBER key (6, Fig. 3) to change the telescope’s slew speed. Each time you
press a number from 1 through 9, the speed will change. See SLEW SPEEDS, page 18, for
more information.
7. Use the red dot viewfinder (7, Fig. 1 or 2) to locate an object and practice using the
AudioStar’s Arrow keys to center the object in the telescope eyepiece’s field of view.
8. Use the telescope’s focus knob (1, Fig. 1 or 2) to bring the object into focus.
Slew Speeds
AudioStar has nine slew speeds that are directly proportional to the sidereal rate (see TO TRACK
AN OBJECT AUTOMATICALLY below for a definition of “sidereal rate”) and have been calculated
to accomplish specific functions. Pressing a number key changes the slew speed, which is
shown for about two seconds on AudioStar’s display.
The nine available speeds are:
• Number 1 = 1x = 1 x sidereal (0.25 arc-min/sec or 0.004°/sec)
• Number 2 = 2x = 2 x sidereal (0.5 arc-min/sec or 0.008°/sec)
• Number 3 = 8x = 8 x sidereal (2 arc-min/sec or 0.033°/sec)
• Number 4 = 16x = 16 x sidereal (4 arc-min/sec or 0.067°/sec)
• Number 5 = 64x = 64 x sidereal (16 arc-min/sec or 0.27°/sec)
• Number 6 = 0.5° = 120 x sidereal (30 arc-min/sec or 0.5°/sec)
• Number 7 = 1°/s = 240 x sidereal (60 arc-min/sec or 1°/sec)
• Number 8 = 1.5°/s = 360 x sidereal (90 arc-min/sec or 1.5°/sec)
• Number 9 = Max = (Maximum speed possible, dependent on battery power)
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 low-to-moderate power
eyepiece, such as a standard 26mm eyepiece.
Speeds 7 or 8: Best used for rough centering of an object in the eyepiece.
Speed 9: Moves the telescope quickly from one point in the sky to another.
Playing the Audio
The StarNavigator telescope is equipped with Astronomer Inside technology. This
revolutionary technology provides object descriptions of night sky objects while you are
viewing them. Object descriptions for the Moon, planets, stars, clusters, nebulae and galaxies
are presented by Astronomer Inside. Information such as temperature, size, distance and
mythology are presented in a fun and entertaining way.
To activate Astronomer Inside technology a night sky object needs to be selected. To select
an object, go to the Object menu. See page 25 on navigating the Objects menu.
Once an object is selected on the AudioStar, an audio presentation for that object will begin
to play. While the audio is playing, the volume can be adjusted by pressing the 7 (volume
down) or 9 (volume up) keys. To skip the current audio file and play the next, press the ? key.
If there are no other audio files for that object, the audio will stop playing. If multiple audio files
are available, keep pressing the “?” key to skip the audio until it stops.
