e. “Automatic Alignment: Selecting Star” and 
“Slewing” display. When it is close to the 
alignment star “Center Brightest Star: Press 
“ENTER”” displays. When the telescope slews 
to the fi rst star, it may not appear in the fi eld 
of view in the eyepiece. Use the Red Dot 
Finder (Pg. 12, Fig. 2, 16) to locate the star. 
The alignment star will be easy to recognize 
— it will be the brightest star in the area of 
the sky where the telescope is pointing. Use 
the Arrow keys to center the alignment star in 
the eyepiece. When the alignment star 
is centered, press “ENTER”. Repeat the 
procedure for the second alignment.
 f.  The telescope now slews to the second 
   alignment star. LS displays “Center 
  Brightest Star”.
 g. “Press “ENTER”” displays. Use the Arrow 
    keys to center the alignment star in the 
    eyepiece. When the second alignment star is 
  centered, press “ENTER”. 
h.  “Alignment successful” displays. If “Alignment 
Unsuccessful” displays, perform the 
procedure again. 
NOTE: If you have an obstruction, such as a tree 
or a building blocking your view of the alignment 
star, or if you have any doubts at all about the star 
that has been chosen, no problem. Just press the 
SCROLL DOWN key and LS will fi nd another star to 
align upon. 
NOTE:  The selected alignment stars may vary 
by date and time. All that is required is for the 
observer to center the selected stars in the 
eyepiece when prompted.
IMPORTANT NOTE: The “Telescope: Mount” option 
of the Setup menu is set to “Alt/Az” as the default 
alignment by the factory. The example presented 
in this section assumes that you are performing 
an alignment procedure for the fi rst time with your 
telescope and therefore, the “Telescope: Mount” 
option does not need to be selected. 
Two Star Alt Az Alignment
 1. Select Alt. Az. 2 Star alignment from the Align 
    menu to begin two star alignment. 
 2.  “Automatic Alignment” displays. The system now 
    performs the following routines (press any ETX-
    LS key to abort Automatic Alignment).
  Caution:  As the telescope performs the 
    following operations, it will swing and rotate. Keep 
    a safe distance from the telescope. The telescope 
  now fi nds the level and tilt position of the 
    telescope, and also detects where true North is. 
    It may not actually level or tilt the telescope or 
    point to North — it is just detecting these positions. 
    This may take a minute or two. 
a.  Attempts a “GPS Fix”. The GPS receiver 
attempts to acquire and sync up with 
signals from GPS satellite system. 
“Getting GPS Fix” displays Note: Press 
Mode key to abort the GPS fi x.  You 
will then be prompted to enter the time, date 
and location. 
b.  Detects “level” of the base of the telescope; 
fi nds tilt and tip. To detect level, LS 
must calculate “level” at three compass 
points. LS also determines the 
positioning (i.e., tilt and tip) of the 
optical tube. 
c.  Finds North. Locates magnetic North, then 
calculates true North. 
 NOTE: After performing these operations, LS 
 now knows: 
 •  The telescope’s limiting positions
 •  Where level is for the telescope
 •  The location of true North
 •  The observing site’s location
 •  The date and time 
 d.  Once the level, tilt and North are detected, 
    the telescope will “GO TO” 2 alignment 
    stars. The telescope will go to these stars in
    order to orient itself to the sky. Once it has
    done this, it will be able to point to any one of
    nearly 100,00 objects in its database.
