Kowa TSN-88 PROMINAR with TE-11WZ ll zoom eyepiece

The TSN-88 sets the standard for long-range observation, built around a premium 88mm pure fluorite crystal objective lens — the optical heart of Kowa's Prominar flagship line. Paired with a concave XD lens and enhanced coatings on both lens and prism, it delivers exceptional light transmission across the full color spectrum, producing a brilliant, natural image with virtually no chromatic aberration, even at max magnification.

Key Features:

• 88mm pure fluorite crystal objective lens for stunning color brilliance and detail

• Dual focus system (stacked quick-focus and fine-focus wheels) for fast acquisition and pinpoint precision

• Strong-yet-lightweight magnesium alloy chassis with Kowa KR coating to repel dirt, moisture, and dust

• Waterproof to JIS Class 7, nitrogen-filled to prevent internal fogging

• Dual tripod mounting system prevents slipping/rotating during extended glassing sessions

• Detachable aiming sight plus built-in sunshade sight for faster target acquisition

• Bayonet accessory collar — fully compatible with the Kowa System, including digiscoping adapters
