Fluorite optics and integrated zoom eyepiece

The Prominar fluorite element eliminates colour aberrations, ensuring a sharp, bright image with natural colour tones. The TE-11WZ II wide-angle zoom lens, integrated into the body, offers 17–40x magnification. The field of view is up to 52 % wider than that of its predecessor, the TSN-550.

Precise adjustment and durable construction

With dual focusing, you can quickly get the image roughly in focus and then fine-tune it as conditions change. The fully sealed, nitrogen-filled body is waterproof, and the lens’s KR coating helps to keep the view clear in changing weather conditions.

Digiscoping with a smartphone or camera

With Kowa’s smart adapters, you can attach a smartphone or a system camera to a telescope, turning it into a compact telephoto system for long-distance nature photography.
