Computerised Handset with LED display
NOTE!
Note that the coordinates of Saturn
(and other planets) change constantly
over the course of a year. If the selected
observation object (e.g. Saturn) is not
visible below the horizon at the set
observation time and location, this is
indicated on the LCD with the message
"Target under Horizon". In this case,
press the MODE button once and select
another object from the database.
NOTE!
If the tracking was stopped by
accidentally pressing the MODE button,
the tracking can be switched on again
by pressing the STOP button twice.
Navigation to the observation objects
"Go To Saturn
This exercise shows you how to select a celestial object, Saturn, for observation from the
basic data of your handheld computer.
1. After the telescope is aligned, the main screen appears on the LCD of the handheld
computer. Press ENTER and you are in the main menu. Use the direction buttons to
select "Navigation" and press ENTER.
2. Y ou are in the submenu "Navigation" and various options of stored observation objects
appear which can be approached with the help of the telescope control.
3. S elect "Solar System" and press ENTER. Mercury" appears in the LCD. Use the "Up" and
"Down" keys to scroll through the database until "Saturn" appears in the display. Press
ENTER. The planet Saturn is now automatically approached by the telescope control. It
could be that you still have to bring Saturn exactly into the center of the eyepiece with
the direction keys.
The control moves the telescope automatically. This will "track" Saturn (or any other
object you have just selected), that is, Saturn will remain permanently in the center of the
eyepiece.
User objects
How to enter the coordinates of an object and approach the object under the "User object"

right ascension axis (Ra) and in degrees/minutes/seconds for the declination axis (DEC).
Note the positive or negative sign of the degree. Save the entries with the ENTER key.
7. Press the MODE button twice to display the main screen.
8. P ress the "F"-key (10, fig. 25) and select the desired memory location. Press ENTER.
The telescope now moves to the previously stored object coordinates. The object is
