A Guide to Birding with Spotting Scopes
The Kowa TSN-773 77mm PROMINAR XD Spotting Scope with Angled Viewing is a scope of world-class caliber that redefines the standards of color brilliance, detail sharpness, and edge-to-edge brightness. Logically tailored to the most demanding outdoor enthusiast, every technical and ergonomic detail that went into the development of the TSN-770 & 880 series spotting scopes has been examined, perfected, or completely reinvented.
This version uses an element of XD (extra-low dispersion) glass in its construction, which greatly minimizes chromatic aberration. This greatly enhances the clarity for crystal-clear images and high color accuracy. Use of Kowa's patented C3 multi-coated optics has made it possible to increase image brightness significantly over prior-generation models. The advanced lens system of these scopes achieves minimal to zero chromatic aberration even at higher magnifications, with consistent high image brightness.
The housing is made of magnesium alloy that is designed for maximum durability and lightweight body construction. The result is a compact, ergonomic, and functional design for the die-hard enthusiast who wants only the very best.
C3 Coating
C3 Coating is a highly reflective multi-coating of dielectrics. This allows for a much higher reflectivity than with coatings of silver or optically enhanced aluminum, offering a reflectance of 99% or higher across the entire visible spectrum. Not only does this provide bright and sharp images, but accurate color reproduction is also achieved.
Inner Focus System
The innovative inner focus system decreases image movement when focusing on objects, even single handedly. The focus system has the ability to focus from 16.4' (5 m) to infinity in two quick revolutions of the focus knob, ensuring consistent viewing.
Water and Fogproof
The waterproof housing meets the rigorous standards of JIS Protection Class 7; it is also charged with dry nitrogen gas to prevent fogging.
Choice of Eyepieces
Multiple interchangeable eyepieces are available, including 20x-60x zoom, 30x wide, and 25x LER for total versatility in the field. The eyepiece locking mechanism prevents the eyepiece from falling out or getting lost. Converters allow users to utilize eyepieces from other Kowa spotting scope series.
