QHYCCD Medium OAG
There are three models of QHYOAG: QHYOAG-S, QHYOAG-M, and QHYOAG-L for different size sensors. The QHYOAG is a thin and solid design. The OAG main body is just 10mm thick. Adding an M42 thread or M54 adapter ring adds only 3mm for a total thickness of 13mm. There are six 3mm through holes in the OAG for direct connection to the QHYCFW2 and QHY “A” series cameras. If you do not have a QHYCFW2 or QHY “A” series camera, you can also use this OAG with a third-party adapter ring on the camera side. The QHYOAG comes with a multithread 1.25-inch focuser. The focuser has a locking thumbscrew to hold the guide camera fixed after focusing. The prism position can be adjusted and can be locked to fix its position. The prism is 8mm x 8mm size and the aperture between the prism and mirror is 8mm in diameter.
Stable and Strong / High Parallelism
Direct connection to the camera with six screws ensures connection accuracy and parallelism, providing a reliable mechanical connection for your photography.
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.
Compatibility: Multiple Adapters / Flexible Combinations
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.
Stable and Strong / Precise Easy Focusing
The QHYOAG includes a precision 1.25-inch helical focuser that accepts our QHY5II and QHY5III cameras. The focusing process is comfortable. After focusing, you can lock the focus mechanism with thumbscrews.
