Kowa Eyepieces are made to mate seamlessly with Kowa Spotting Scopes. Compatible models include the TSN 600 Kowa 60mm Spotting Scopes and the TSN 660 Kowa 66mm Spotting Scopes, and Kowa 82mm TSN 82SV Scopes - any of these can be coupled with any of the several Kowa Interchangeable Eyepieces offered here, to meet your specific needs. There are single magnification models and zooms, and some have apparent viewing angles (real viewing angle multiplied by the magnification factor) of >60°.
Kowa TSN-660 / TSN-600 Spotting Scopes Eyepieces:
- TE-17HD: Kowa 25x LER Long Eye Relief Eyepiece
- TE-14WD: Kowa 30x Wide Angle Eyepieces

Note: does not fit older Kowa 821, 822, 823, 824 scopes.
Choose for your Kowa Spotting Scope one of the Kowa Interchangeable Eyepieces with a wide apparent field of view (greater than 60°) if you don't wear thick glasses and want to be "swimming in field". This will provide you with more real field for a given magnification than can ever be had from a zoom eyepiece, allowing easier subject tracking with the benefit of more observable detail thanks to the increase in magnification.
If you have to wear thick glasses, select a Kowa Spotting Scope Eyepiece with long eye relief. These have a profoundly-long distance between the rear element and the location which your pupil can be while still being able to observe the entire field of view. Naturally, this comes at the cost of less apparent field of view, but if you must wear glasses or sunglasses it is the most comfortable option for use.
