Kowa TSN-55 PROMINAR spotting scope

Travel Light — See Bright. The TSN-55 PROMINAR brings the same sharp, aberration-free viewing of Kowa's larger flagship scopes into an ultra-compact, sub-1kg package. It's built around a 55mm pure fluorite crystal objective lens — the same premium glass used across the Prominar line — and comes with Kowa's TE-11WZ II eyepiece built directly into the body, delivering a 17-40x magnification range with an exceptionally wide field of view (a 52% FOV improvement over its predecessor, the TSN-550).

Key Features:

• 55mm pure fluorite crystal objective lens for color-accurate, aberration-free clarity

• Integrated TE-11WZ II eyepiece (17-40x) — no separate eyepiece to buy or lose, ready to use out of the box

• Dual fast/fine focus system for quick acquisition and precise detail work

• Fully sealed, nitrogen-purged to prevent internal fogging from temperature swings

• Ultra-compact and lightweight: ~10" long, under 1kg

• Twist sunshade and 58mm filter thread for accessories

• Digiscoping-compatible eyepiece thread for camera/smartphone adapters
