QHY CCD QHYOAG-L, Off Axis Guide, Large



QHY CCD QHYOAG-L, Off Axis Guide, Large
 
QHY OAG -  Thin and Flexible Setup
 
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 camera.  If you do not have a QHYCFW2 or QHY "A" series camera, you can also use this OAG with a third part adapter ring on the camera side.  
 
There are three models of QHYOAG:  QHYOAG-S, QHYOAG-M, and QHYOAG-L for the different size sensors (See table below). 
 
The QHYOAG comes with a multi-thread 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 aperature between the prism and mirror is 8mm in diameter.
