Precision Connection No Deflection
The main purpose of the OAG is to use the same optical path as the main camera. This avoids the problem of differential deflection that can occur when using a separate optical system for guiding. In the case of the OAG, a part of the image is picked-off from the edge of the imaging circle which does not block the main CCD. This method provides more accurate guiding and sharper images.
In addition to the connection with the A-series cameras, you can also use the various standard or optional accessories provided by QHYCCD to achieve complex and adaptable connections, including the use of the OAG as a stand alone unit, connection to QHY filter wheels, etc.
