Love the wide field-of-view and sharpness of this at the regular, non-zoom focal length. However as soon as you zoom in, it becomes nearly impossible to focus, making the zoom 'feature' useless. But since there is no other option that I'm aware of for the wide angle, it's what you have to go with.

the images I have looked at through this eyepiece are very clear and sharp. I could see objects a mile away. it also will give you a clear picture of things about 25 feet away. I bought it to watch birds with.

The Kowa TE-11WZ Prominar 25-60x Zoom Eyepiece is a weather-resistant spotting scope accessory designed to complement the optical excellence of Prominar series scopes. This high-powered zoom eyepiece features Kowa's extra-low dispersion (XD) glass elements, which transmit color faithful images with enhanced contrast and sharpness. When mounted to one of the 770 or 880 spotting scopes, the TE-11WZ has a 25-60x zoom range; on the 500mm f/5.6 Photoscope, the zoom range is 28-66x. A wide apparent viewing angle, 60-79deg. on the 770 or 880 scope, provides immersive views throughout the zoom range. Additionally, the eyepiece's long 17mm eye relief is constant at any magnification setting, providing a comfortable viewing distance even at maximum power.
