Enabling the use of your camera with a variety of select Kowa spotting scope eyepieces, the TSN-DA20 Digiscoping Adapter is an interface between the eyepiece and either the camera body or the camera lens. This adapter can be rotated while attached to permit quick switching between horizontal and vertical shooting orientations.

The adapter attaches to spotting scope eyepieces by replacing the eye-relief cap with the adapter's inner collar and then attaching directly to a lens or a camera body through the use of additional adapters. A 43mm adapter ring is included for attaching to lenses featuring 43mm front filter threads, or the optional TSN-AR42 GT Adapter Ring can also be used for attaching a T2 adapter ring to mount directly to the camera.
