QHYCCD off-axis guiders are available in 3 different sizes to suit a wide range of astrophotography cameras with sensors as large as 48mm x 36mm. All models have 10mm thickness and an 8mm x 8mm multi-coated prism that picks off the beam for the guide camera. The position of the prism can be adjusted as needed and locked down. 

Each QHY OAG includes a non-rotating helical 1.25" focuser with a 6mm range to help focus an image on your guide camera. When using the QHY5II and QHY5III, the position of these cameras can be further adjusted in the OAG itself to accommodate a wide range of back focus.
