The Kowa TE-80XW Wide Angle Eyepiece offers a truly immersive optical experience using a field flattener and XD lens. It produces a 40x fixed magnification with the TSN-99 Prominar Series and a 35x fixed magnification with the TSN-880/770 Prominar Series. The extremely wide field of view allows you to find your subjects quicker by providing a greater overview of the area you are observing. Not only this, but it also makes images absolutely stunning!
The eyepiece is fully waterproof and sealed against the elements, so you can be sure that it will be ready for whatever the elements throw at it! As well as this, it also features an additional KR coating which further protects against the elements by actively reducing the build-up of dust, dirt and other such particles.
With its field flattener and XD lens, the Kowa TE-80XW Wide Angle Eyepiece provides images that are ultra-sharp across the entire view. These also ensure that the image is completely uniform and virtually free of chromatic aberration. As a result, the view in front of you is recreated in incredible detail and clarity.
