Direction Buttons
The hand control has four direction buttons in the center
of the hand control which control the telescope motion in
altitude (up and down) and azimuth (left and right) The
telescope can be controlled at nine different speed rates
1 = 2x
2 = 4x
3 = 8x
4 = 16x
5 = 32x
Motor Speed Button
Pressing the MOTOR SPEED button (12) allows you
to instantly change the speed rate of the motors from
high speed slew rate to precise guiding rate or anywhere
in between Each rate corresponds to a number on the
hand controller key pad The number 9 is the fastest rate
(approximately 4° per second, depending on power source)
and is used for slewing between objects and locating
alignment stars The number 1 on the hand control is the
slowest rate (2x sidereal) and can be used for accurate
centering of objects in the eyepiece To change the speed
rate of the motors:
• Press the MOTOR SPEED key on the hand control
The LCD will display the current speed rate
• Press the number on the hand control that corresponds
to the desired speed
The hand control has a "double button" feature that allows
you to instantly speed up the motors without having to
choose a speed rate To use this feature, simply press the
arrow button that corresponds to the direction that you want
to move the telescope While holding that button down,
press the opposite directional button This will increase the
speed to the maximum slew rate
When using the UP and DOWN buttons on the hand control,
the slower slew rates (6 and lower) move the motors in the
opposite direction than the faster slew rates (7- 9) This is
done so that an object will move in the appropriate direction
when looking into the eyepiece (i e , pressing the up arrow
button will move the star upwards in the field of view of the
eyepiece) However, if any of the slower slew rates (rate 6
and below) are used to center an object in the starpointer,
you may need to press the opposite directional button to
make the telescope move in the correct direction
Help Button
In future firmware updates, this button will offer troubleshooting
tips For your convenience, it currently functions as a shortcut
to the Messier Catalog
6 = 3° / sec
7 = 1° / sec
8 = 2° / sec
9 = 4° / sec
Menu Button
The CGX mount contains many user-defined setup
functions designed to give the user control over the
telescopes many features All of the setup and utility features
can be accessed by pressing the MENU key and scrolling
through the options below
Tracking Menu
Tracking Mode – This allows you to change the way the
telescope tracks depending on the type of mount being used
to support the telescope The telescope has three different
tracking modes:
• EQ North – Used to track the sky when the telescope is
polar aligned in the Northern Hemisphere
• EQ South – Used to track the sky when the telescope
is polar aligned in the Southern Hemisphere
• Off – When using the telescope for terrestrial (land)
observation, the tracking can be turned off so that the
telescope never moves
Tracking Rate – In addition to being able to move the
telescope with the hand control buttons, your telescope
will continually track a celestial object as it moves across
the night sky The tracking rate can be changed depending
on what type of object is being observed:
• Sidereal – This rate compensates for the rotation of the
Earth by moving the telescope at the same rate as the
rotation of the Earth, but in the opposite direction When
the telescope is polar aligned, this can be accomplished
by moving the telescope in right ascension only
• Lunar – Used for tracking the Moon when observing the
lunar landscape
• Solar – Used for tracking the Sun when solar observing
with the proper filter
View Time-Site Menu
This menu displays the current time and longitude/latitude
downloaded from the optional SkySync GPS receiver
It will also display other relevant time-site information like
time zone, daylight saving and local sidereal time Local
sidereal time (LST) is useful for knowing the right ascension
of celestial objects that are located on the Meridian at that
time View Time-Site will always display the last saved time
and location entered while it is linking with the GPS Once
current information has been received, it will update the
displayed information If GPS is switched off or not present, the
hand control will only display the last saved time and location
The Hand Control Menu
The "Hand Control" menu allows you to customize certain
features of the NexStar+ hand control To access this menu,
press the MENU button (#7 on the keypad) and use the
scroll buttons to select "Hand Control" and press ENTER
