ZWO M48(M)-M48(F) extender(16.5mm)

OAG-L has a large prism size of 12*12mm, far bigger than M68 OAG. The bigger clear aperture brings wider field of view in guiding. It is easy to use, and suitable for users who are interested in long focal length photography.

To take the most advantage of it, we recommend you to match it with large format guiding cameras.
