Rate Button

Pressing the RATE key (11) 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 (3º 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 (.5x sidereal) and can be used for accurate centering of objects in the

eyepiece and photographic guiding. To change the speed rate of the motors:

 Press the RATE 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 number will appear in

the upper-right corner of the LCD display to indicate that the rate has been changed.

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 the

maximum slew rate.

The direction that a star moves in the eyepiece when a direction is pressed will change depending on which side of the

Meridian the telescope tube is positioned. In order to change the direction of the arrow buttons, see

Scope Setup Features later

in this section.

1 = .5x 6 = 64x

2 = 1x (sidereal) 7 = 1º / sec

3 = 4x 8 = 2º / sec

4 = 8x 9 = 5.5º / sec

5 = 16x

The Hand Control 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 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:

Nine available slew speeds

1 2 ... 19 20 21 22 23 24 25 26 27 28 29 ... 71 72
