Remarkably small and lightweight, the TSN-55 PROMINAR Spotting Scope from Kowa offers the same sharp, aberration-free viewing experience as its larger siblings in a highly compact package. The 10" scope comes with Kowa's TE-11WZ II eyepiece built into the body, with a magnification range of 17-40x, and its pure fluorite crystal objective lens all but eliminates fringing for color accuracy and clarity. Dual fast/fine focus makes it easy to dial in the details of your subject. Designed and manufactured in Japan, the scope is fully sealed and nitrogen-purged to prevent internal fogging from abrupt temperature changes. It comes with a twist sunshade, a 58mm filter thread, and an eyepiece thread for attachments including digiscoping adapters.

Optical Performance
  • 55mm aperture
  • Ultralow dispersion PROMINAR fluorite glass elements eliminate chromatic aberration, which causes halos, astigmatism, and fringing, for improved color rendition and contrast
  • Built-in 17-40x TE-11WZ II PROMINAR wide-angle zoom eyepiece with two extra-low dispersion lenses for a sharp image and a generous field of view
Use and Handling
  • Integrated aiming sight
  • Smooth and precise fine and coarse two-speed focusing mechanism
  • 58mm objective lens filter threads
  • 1/4"-20 mount to accommodate most photo, video, and field tripods
Construction Details
  • Lightweight and impact-resistant chassis
  • Nitrogen filled, waterproof, and resistant to internal fogging when moving through extreme temperature changes and conditions
  • Oil-resistant KR exterior lens coatings make it easy to clean dirt, sap, and oil without leaving smudges or residue
  • Retractable sunshade reduces glare and lens flare, keeps snow and rain off the objective for clearer viewing
