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 slew rate to
approximately 1º per second (equal to rate 7 on the hand control). This feature will not function if the telescope is currently
set at a speed rate of 8 or 9.
The slower slew rates (6 and lower) move the motors in the opposite direction than the faster slew rates (8 and 9). This is
done so that an object will move in the appropriate direction when looking into the eyepiece (i.e. pressing the right arrow
button will move the star towards the right 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 Star Pointer, you may need to press the opposite directional button to
make the telescope move in the correct direction.
1 = 2x 6 = .5º / sec
2 = 4x 7 = 1º / sec
3 = 8x 8 = 2º / sec
4 = 16x 9 = 4º / sec
5 = 32x

The NexStar contains many user defined setup functions designed to give the user control over the telescope's many
advanced features. All of the setup and utility features can be accessed by pressing the MENU key and scrolling through the
options:
Tracking Mode
Once the NexStar is aligned the tracking motors will automatically turn on and begin
tracking the sky. However, the tracking can be turned off for terrestrial use:
Alt-Az
This is the default tracking rate and is used when the telescope is placed on
a flat surface or tripod without the use of an equatorial wedge. The
telescope must be aligned with two stars before it can track in Alt-Az.
EQ North
Used
to track the sky when the telescope is polar aligned using an
equatorial wedge in the Northern Hemisphere.
EQ South
Used to track the sky when the telescope is polar aligned using an
equatorial wedge 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, the NexStar
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:
Nine available slew speeds
