Kowa TSN-99 PROMINAR with TE-11WZ ll zoom eyepiece

The TSN-99S PROMINAR is Kowa's flagship spotting scope, built around a massive 99mm objective lens crafted from pure fluorite crystal — the largest in Kowa's straight-viewing lineup. Paired with a Kowa XD concave lens, it delivers exceptional light transmission and virtually eliminates chromatic aberration, even in low light at dawn and dusk.

Key Features:

• 99mm fluorite crystal objective lens for razor-sharp, high-contrast, true-color images

• Dual focus system for fast, precise focusing at any magnification

• 100% magnesium alloy body — rugged yet remarkably lightweight for a large-objective scope

• Fully waterproof, nitrogen-sealed (JIS Class 7) to prevent internal fogging in any weather

• Bayonet eyepiece mount — fully compatible with the Kowa System, including interchangeable eyepieces and digiscoping adapters for DSLR/smartphone

• Retractable sun shade and standard 1/4"-20 tripod mounting thread
