Kowa – TSN-554 15-45×55 PROMINAR Spotting Scope (Straight Viewing)

A Guide to Birding with Spotting Scopes

At less than a foot long, the straight-through viewing Kowa TSN-554 15-45×55 Spotting Scope is the ideal companion wherever you go to glass. It employs the ultra-low dispersion PROMINAR fluoride glass that eliminates chromatic aberrations that, when coupled with the fully multi-coated optics and two-speed focusing mechanism, produce bright and clear tack-sharp high-contrast images with accurate color rendition for an immersive observational experience. The impressive zoom range allows you to take in a wide field of view for general viewing purposes, with the ability to draw subjects in close for more detailed observations. This version of the TSN-550 is configured with the eyepiece set in-line with the optical tube for straight-through viewing to make acquiring subjects easy and tracking moving subjects fast.

To reduce weight, without sacrificing strength or durability, the chassis is made of a polycarbonate material and wrapped in a slip-resistant armoring. A rubberized and textured zoom collar and focus wheel make adjustments fast and easy, even when wearing gloves. The optical tube is nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes or environmental conditions. To increase your mounting options, the TSN-554 comes outfitted with both a 1/4″-20 and 3/8″-16 tripod attachment—making it compatible with most photo, video, and field tripods on the market.
