Hi all,
up for sale is a QHYCCD OAG-M Off-Axis guider.
It includes two sets of adapters to suit different cameras depending on the chip size of the camera. One set is the M42.0.75 rings which are attached in the pic,
and the other set is the M54/0.75 as shown below. Solid and adaptable guiding solution, can be connected to cameras and/or filter wheels.
In excellent condition, now surplus for me.
More details here if you wish to see more.
