Note

QSI 500 Series cameras have a Guider port on the bottom of the camera.  This port sends 
guider correcting signals to your telescope mount.  Connect the included guider cable from the 
camera Guider port to the AutoGuider port on your telescope mount.  The guider correction 
signals output by the QSI 500 will work with most modern telescope mounts using the included 
guider cable. 

 
The photo to the left shows the guider 
cable connected to the AutoGuider 
port on a Losmandy Gemini System.  
Please refer to your camera and 
mount specifications to confirm your 
mount is compatible with the signals 
from the QSI 500 Series camera.  QSI 
offers an optional Guider Break-Out 
Box (GBOB) for connecting to older or 
non-standard mounts.  Please see the 
QSI web site for complete details.
