The Kowa TE-17W 30x Wide-Angle Eyepiece is a wide-angle eyepiece compatible with the TSN-880 and 770 series spotting scopes. The wide-angle eyepiece is ideal for those that don't wear thick glasses and want to be "swimming in field". This will provide you with more real field than with a zoom eyepiece, allowing easier subject tracking with the benefit of more observable detail thanks to the increase in magnification.
- Waterproof and nitrogen filled for all-weather use.
- Large apparent viewing angle of 72°.
- Bayonet mount, can be silently changed in the field.
