This menu option allows you to define and store 
terrestrial objects in the Landmark database. First, 
a landmark needs to be stored in memory using the 
“Landmark: Add” option. To view a landmark, use the 
“Landmark: Select” option. 
To add a landmark to the database
In this procedure, you will store the location of terrestrial 
landmarks in LS-6’s memory. 
 1. Set the telescope in the home position, if 
 necessary. Note for future reference where 
 the telescope is located and if you have aligned 
 the telescope, which alignment method is used. 
 IMPORTANT NOTE: To use the Landmark 
 function, the telescope must be located and 
 aligned exactly as when the landmark) was 
 added to the database. 
 2. Display the “Setup: Targets” menu option. Chose 
 “Terrestrial” and press “ENTER”. Choosing this 
 option turns off tracking for astronomical objects. 
 Be sure to change this option back to 
 “Astronomical” when you wish to view celestial 
 objects again. 
 3. Press “BACK” once. “Select Item: Setup” 
 displays. 
 4. Press the Scroll Down key once and “Select 
 Item: Object” displays. Press “ENTER”. “Object: 
 Solar System” displays. 
 5. Press the Scroll Up key twice and “Object: 
 Landmarks” 
displays
Press
“ENTER”.
“Landmark: Select” displays.
 6. Press the Scroll Down key once. “Landmark: 
 Add” displays. Press “ENTER”. 
 7. “Landmark Name” displays. Using Arrow keys, 
 enter a name for the landmark you wish to add to 
 the database. When finished, press “ENTER”. 
Alt/Az 1 Star Alignment
One-Star Alignment requires some knowledge of the 
night sky. LS-6 provides a library of bright stars. One-
Star Alignment is identical to Two-Star Alt/Az: Alignment 
(see TWO-STAR ALT/AZ ALIGNMENT above), except 
only one star from the database is chosen by the 
observer for alignment. 
Finding Objects Not in the Database
Although LS-6 contains an extensive database of 
celestial objects (stars, nebulae, planets, etc.) that you 
can observe, you may eventually want to view objects 
that are not part of the database. LS-6 provides a 
feature that allows you to enter an object’s R.A. and 
Dec. and allows automatic slewing of the telescope to 
the user-entered coordinates. 
In order to use this option, you first need to look up the 
R.A. and Dec. coordinates of the object or objects you 
wish to observe. Check out the Internet, local library, 
or bookstore for astronomy books, CD ROMs, or 
magazines (such as Sky & Telescope or Astronomy), 
to find coordinates of celestial objects.
To enter coordinates of an object into the 
Telescope:
 1. Make sure LS-6 has been initialized and the 
 telescope has been aligned. 
 2. From any menu press the “MODE” key to change 
 to Scope Info mode.
 3. Scroll the display until the telescopes Current 
 RA is displayed. 
 4. Press the “GO TO” key. The scope will now prompt 
 you to enter the object’s coordinates.
 5. “Right Asc.: 00.00.0” displays. Use the Number 
 keys to enter the digits for the Right Ascension 
 coordinate of your object. When you are finished, 
 press “ENTER”. 
 6. “Declination: +00°.00’” displays. Use the Number 
 keys to enter the digits for the Declination 
 coordinate of your object. If necessary, use the 
 Scroll Keys to change “+” to “-”. When you are 
 finished, press “ENTER”. 
7. The telescope will now slew to your object.
