A simple alignment/synchronization can be performed to improve the GOTO and 

tracking accuracy. To do so, press MENU button, scroll down to “Align”, select “One Star Align” 
and press ENTER. A list of three bright objects, such as Moon, Venus, and other stars, will be 
displayed for you to select from. Select an object using ▲ or ▼ key. Then press ENTER. Use ◄ 
► ▲ or ▼ key to center the object in your eyepiece. Press SPEED button to change the slew 
speed if needed. Then press ENTER to complete the alignment. Or press the BACK key to 
cancel the process. 

You may need to use SPEED key to change the slewing speed to make the centering 

procedure easier. 

An alternate way is performing “Sync to Target”. To do so, press MENU button, select 

“Select and Slew” and press ENTER. Then select a known sky object, such as Moon from 
“Planets, Sun, Moon” menu and press ENTER. The mount will slew to the Moon. When the 
mount stopped slewing, the Moon could be just inside your eyepiece or way off. Press MENU 
button and scroll down the menu to “Sync to Target” and press ENTER. Follow the instruction, 
use ◄ ► ▲ and ▼ keys to move the Moon in the center of your eyepiece and press ENTER.  

 

When finishing observing, always move the mount to Park Position. If the mount is not 

moved, no initial set up is needed when powered on the next time. To do so, press the MENU 
button, scroll down to “Park Telescope” and press ENTER. Turn the power off.
