The extension ring goes between the TSN-DA1 Digital Camera Adapter and either the camera filter adapter or the TSN-DA4 Universal Camera Mount. It both allows for the greater length of the zoom eyepieces and gives access to the eyepiece's zoom ring so you can zoom the eyepiece with the camera in place.
