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. This method provides more accurate guiding and sharper images. QHYOAG includes a precision 1.25-inch helical focuser that accepts the QHY5II and QHY5III cameras. After focusing, you can lock the focus mechanism with thumbscrews.
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 QHYCFW and QHY A Series cameras.
