2. Mount/GPS Status: display current 
status of the mount. If the mount equipped 
with an external GPS module, it also 
indicates GPS status, when the mount is 
turned on. 

•  Land (Mount Status): the telescope is at 

a standby position or observing a land 
object; 

•  Sola (Mount Status): the telescope is 

tracking an object in Solar system at a 
solar speed; 

•  Luna (Mount Status): the telescope is 

tracking the Moon at the lunar speed; 

•  Cele (Mount Status): the telescope is 

tracking a celestial object at a Sidereal 
speed;  

•  G-ON (GPS Status): GPS is connected 

and trying to lock on the satellite; 

•  G-OK (GPS Status): The connection 

between GPS receiver and satellites 
has been established. It will be replaced 
by Mount Status after a few minutes. 

3.  R: Right Ascension of the telescope, or 
R.A. 
 
4.  D: Declination of the telescope, or DEC. 
 
5.  A: Altitude of the telescope (zenith is 
90º). 
 
6.  Z: Azimuth of the telescope (north is 0º, 
east 90º, south 180º, and west 270º). 
 
7.  Local Date and Time: display local time 
in a format of YY-MM-DD HH:MM:SS. 
 
8.  Slew speed: It has 5 speeds: 2X, 8X, 
64X, 256X(1º/sec), MAX(4º/sec). Press 
SPEED key to change it. 

In order to experience the full GOTO 
capability of GOTONOVA technology, it is 
very important to set up the mount correctly 
before observation.  

Level the mount by 
observing the 
bubble (shown) on 
the base of the 
mount by adjusting 
the tripod legs. 
The bubble should 
be in the center of 

the circle. It is also recommended to use 
additional levelers (such as a torpedo 
leveler) to assure precise leveling. Turn the 
mount around by pressing ► or ◄ button to 
make sure it is always leveled during 
movement.  

Each time the mount is turned on, the 
default position is Park Position, i.e.,its 
altitude is 90º0.0’ and azimuth is 180º0.0’, 
which means the “SOUTH” mark is pointing 
to south and the telescope is pointing 
straight up at the zenith. To set the Park 

Position, you can do one of the following: 

1.  Align the mount to south by turning the 
mount so that the South mark facing south. 
An additional compass is needed. Unlock 
the altitude lock (#4) and rotate the 
telescope to point straight up at the Zenith. 
A torpedo level may help. Make sure the 
mount is leveled. Then turn the mount 
power on.
