    If its brightness is good, the indicator will stop going on and off and 

will remain it. 

 
If the guide star is too bright for AGA-1, the [+] red indicator will be 
lit. 
 
If it is too dark, the [-] red indicator will be lit. 

 
5.  Finding another guide star 
 

If the guide star is too bright or too dark, find another guide star. 
 
After centering it on the monitor screen, press the “Level Check” 
key again. 
 
Note: a) The “Level Check” key is also used for resetting AGA-1. 

For rechecking brightness of the guide star, press the 
key and all the LED lights will go out. 

If you press the key again, AGA-1 will begin to check 
brightness. 
 

                  b) Avoid using a double star as the guide star. The double 

star may cause trouble in guiding. 

 

 
 

DRIVE CHECK MODE 

This mode allows checking the motor speed and turning direction. 
 
1.    Pressing the “Drive Check” key 
 

If you press the “Drive Check” key, AGA-1 will have the right 
ascension and declination motors begin to drive and will compute 
the moving direction and speed of the guide star automatically. 
 
During computing, the drive check indicator’s green light goes on 
and off.
