Kowa Digiscoping-Adapter TSN-DA20

If you want to go digiscoping with your Kowa spotting scope in combination with your digital camera, you can find the available options here. Kowa believes digiscoping should be simple and affordable and therefore offers solutions for Micro Four Third cameras as well as for heavier DSLR cameras.

TSN-DA or TSN-PA adapter

There is a big difference between a TSN-DA and TSN-PA adapter. The TSN-DA must be mounted on the eyepiece while the TSN-PA falls entirely over the eyepiece and attaches to the body of the spotting scope. Cameras with MFT sensors are generally lighter and can therefore be mounted on the eyepiece well with a TSN-DA adapter. DSLR cameras are heavier and need to be connected to the body. A TSN-PA adapter is connected to the body over the eyepiece and provides more stability.
The TSN-PA adapters can be found among the optional accessories.

TSN-DA20 or TSN-DA10

The Kowa TSN-DA20 can be used with the following spotting scopes:

  • Kowa TSN-601/ TSN-66 and TSN-82SV series combined with a TE-Z9B or TE-14WD eyepiece
  • Kowa TSN 550 series
  • Kowa High Lander combined with 21x / 32x and 50x eyepieces

The TSN-DA20 is also compatible with many historical spotting scopes and eyepieces. If you own such a historical model, please inquire about the possibilities.

If you have 1 of the combinations below, choose the TSN-DA20 which can be found under optional accessories:

  • Kowa TSN-99/ TSN-88/ TSN-880 and TSN-770 series spotting scopes combined with a Kowa TE-11WZ or TE-80XW eyepiece.

Important Features Kowa TSN-DA20

On camera body with Kowa TSN-AR42GT 

  1. Unscrew the Twist Up from the eyepiece and screw the DA10 inner ring onto it. This ensures a stable connection.
  2. Mount the optional Kowa TSN-AR42GT adapter ring (see optional accessories) on the DA10 outer ring and connect it to a standard T2 adapter that suits your camera system.
  3. Connect the assembly to your camera body and finally slide the DA10 and camera body combination over the inner ring and secure the assembly with the thumbscrew. You're ready to digiscope.

On filter thread with Kowa TSN-AR adapter rings

If you prefer to connect the whole thing to your camera lens, this is no problem either. You then need a Kowa adapter ring in addition to the TSN-DA10 that fits the filter thread of your camera lens. Kowa has the following available sizes for this: 28, 30, 30.5, 37, 43, 46, 58, 62 and 72mm. If your camera lens has a different filter thread, a step-up or step-down ring can be used without any problems. Ask about the possibilities.


The Kowa TSN-DA20 System works with all sensor sizes, but cameras with heavier lenses may put too much pressure on the filter thread of the lens.
Kowa therefore accepts no responsibility or liability for any damage caused to your equipment when using these adapters.
