While one particular adapter might be recommended, or 'standard', one or more others may work as well, depending on where you desire to attach the iPolar camera. See the list of supported iOptron mounts below. Otherwise, the part number (3339) is for the camera alone. When this is the case, the relevant product part number is for the iPolar camera and its adapter together. Note: Some mounts will require an adapter for fitment, for an additional $20 USD.
