INDEX

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.
