The QHY OAG comes in three versions to accommodate image sensors of various sizes. This is the "small" size. All QHY Off-Axis Guiders have the same main body, including the prism, but the telescope/camera interface is sized to accept thread adapters of different diameters. Regardless of the diameter of the interface, it has six (6) 3mm holes and, without adapters installed, a thickness of 10mm. Both the telescope side and camera side adapters have a thickness of 3mm. The final thickness of the OAG depends on whether you need to use just the telescope side thread adapter or both adapters. The "small" version of the QHY OAG has a diameter of 54mm, and only suits M42x0.75 adapters. This means it supports camera models with sensors smaller than APS-C format, which includes the QHY21/22/23, the QHY9, the QHY8/10/12 and any other model that has a sensor size of less than APS-C. Alternatively, the OAG can be attched directly to the relevant QHY filter wheel.
