From the main menu, select “Align”. Select 
“One Star Align” and press ENTER. A list of 
align stars that are above the horizon is 
computed based on your local time and 
location. Use ▲ or ▼ button to select an 
alignment star and press ENTER.  Center 
the object in your eyepiece using ◄ ► ▲ or 
▼ key. Press SPEED button to adjust the 
slew speed. Then press ENTER to 
complete the alignment. Or press the BACK 
key to cancel the process. 

If you have a very good initial setup, one 
star alignment should be sufficient for good 
GOTO accuracy. To increase the accuracy 
you may choose to do two star alignment. 

 Two star alignment will increase the GOTO 
accuracy of the mount. It is suggested to do 
two star alignment after one star alignment. 
Select “Two Star Align” in the Align menu. 
Use  ▲ or ▼ button to select a star and 
press ENTER.  The mount will slew to it 
automatically. Use ◄  ►  ▲ or ▼ key to 
center the object in your eyepiece. Press 
SPEED button to adjust the slew speed if 
needed. Then press ENTER to complete 
the alignment. After you finish the first star, 
the system will prompt you to choose the 
second star. Repeat the process to finish 
the second star alignment. An “Align OK!” 
screen will show briefly. To obtain a better 
alignment effect, it is suggested to choose 
two align stars far apart.  

“Two Star Align” result will be overridden if 
“One Star Align” or “Sync. to Target” is 
performed after “Two Star Align.” 

 

Besides various star lists available in the 
hand controller, users can add, edit or 
delete their own defined objects. The 
comets and asteroids list also can be 
edited. Up to 128 user objects can be added 

or modified. For comets or asteroids, the 
maximum number is 64, which includes the 
preloaded objects.
