Tour Mode
The Advanced Series telescopes include a tour feature which automatically allows the user to choose from a list of
interesting objects based on the date and time in which you are observing. The automatic tour will display only those
objects that are within your set filter limits (see Filter Limits in the Setup Procedures section of the manual). To
activate the Tour mode, press the TOUR key (6) on the hand control. The hand control will display the best objects
to observe that are currently in the sky.
• To see information and data about the displayed object, press the INFO key.
• To slew to the object displayed, press ENTER.
• To see the next tour object, press the Up key.
Constellation Tour
In addition to the Tour Mode, your telescope has a Constellation Tour that allows the user to take a tour of all the
best objects in each of the 88 constellations. Selecting Constellation from the LIST menu will display all the
constellation names that are above the user defined horizon (filter limits). Once a constellation is selected, you can
choose from any of the database object catalogs to produce a list of all the available objects in that constellation.
• To see information and data about the displayed object, press the INFO key.
• To slew to the object displayed, press ENTER.
• To see the next tour object, press the Up key.
Direction Buttons
The hand control has four direction buttons (3) in the center of the hand control which control the telescope's motion
in altitude (up and down) and azimuth (left and right). The telescope can be controlled at nine different speed rates.
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.
