 Starting astrophotography 

       
      It is now ready to start astrophotography. 

The auto-guiding will continue until the “Pause” key is pressed or 
the guide star is lost. 
 
If you press the “Pause” key, the auto-guiding will be discontinued. 
 
To restart the auto-guiding, press the “Guide” key. 
 
If the guide star is lost by going behind the clouds, the mode 
indicators of the Level Check, Guide and Pause will begin to blink 
red to indicate a guiding error, and the autoguiding will be 
discontinued. 
 
In case of such a guiding error, you cannot restart the auto-guiding 
by pressing the “Guide” key.
