Kowa TSN-66A 66mm Spotting Scope Overview

With its easy portability and a sharp, aberration-free image, the angled-viewing TSN-66A 66mm PROMINAR Spotting Scope from Kowa is built for nature observation in the wild. A separately sold eyepiece is required for use.

The scope's fully sealed, nitrogen-purged housing is made of durable but lightweight magnesium, keeping its weight down to just 2.5 pounds. Kowa's pure fluorite crystal objective lens all but eliminates fringing for color accuracy and clarity, and the dual fast/fine focus makes it easy to dial in the details of your subject. The tripod mount has two holes with adapters that accept both 1/4" and 3/8" posts. A detachable aiming sight on the accessory collar and another, built-in sight on the sunshade help orient the scope toward the subject. The threaded collar with bayonet mount accepts a wide range of accessories, eyepieces, camera adapter for digiscoping, extenders, and more.

Optical Performance
  • 66mm aperture
  • Ultralow dispersion PROMINAR fluorite glass elements eliminate chromatic aberration, which causes halos, astigmatism, and fringing, for improved color rendition and contrast
  • Fully multicoated optics maximize light transmission through the lens to improve image brightness, color rendition, and contrast
Use and Handling
  • Integrated aiming sight
  • Smooth/precise and fine/coarse two-speed focusing mechanism moves through the entire focus range in two turns
  • Rubberized and textured zoom collar and focusing wheel
  • 72mm objective lens filter threads
  • 3/8"-16 and 1/4"-20 mount to accommodate most photo, video, and field tripods
Construction Details

  • 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 for dirt, sap, and oil to be cleaned off without smudges or residue
  • Retractable sunshade reduces glare and lens flare and keeps snow and rain off the objective for clearer viewing
  • Extremely lightweight: 2.5 pounds
