About this product

The TSN-883 Angled 88mm PROMINAR PFC Spotting Scope is a world-class spotter that redefines the standards of color brilliance, sharpness, and brightness.

The TSN-883 uses an element of pure fluorite crystal (PFC) glass in its construction, which greatly minimizes chromatic aberration. This ensures maximum efficiency in its light-gathering, producing a clear visual range and sharp imagery that traditional glass lenses cannot attain at their highest magnifications and with the strongest of subject/background contrast changes. Fluorite is extremely expensive, but the subtle difference between the viewing from the PROMINAR-equipped TSN-883 and even the very best normal scopes would be apparent even to a novice. Kowa's use of their patented C3 prism multi-coating process increases image brightness significantly over their prior-generation models that featured flourite.

The 883's housing is made of a magnesium alloy that defines maximum durability and lightweight construction, resulting in a compact, ergonomic, and functional design for extreme nature and outdoor enthusiasts wanting only the very best. It sets a benchmark for the combination of the large objective with small weight and mass.

As the angled viewing model of Kowa's flagship line, this scope makes sharing the viewing among multiple observers quite easy and is also generally considered more comfortable for longer glassing sessions. An angled scope allows for a slightly smaller, shorter tripod and requires a bit more experience to quickly locate the subject in the scope.

  • Extremely bright 3.5" objective lens garners a better view in any lighting
  • PROMINAR fluorite crystal objective lens element
  • Magnesium alloy construction aids weight/brightness ratio
  • Body's colour tone won't alarm wildlife
  • Phase-corrected Schmidt-Pechan prism with C3 dielectric prism coating, superior to aluminium, mirror, and silver-backed prism systems
  • Dual-speed coarse/fine focusing system
  • Rotating tripod collar with detented intermediate stops
  • Extreme water and fog-proof performance (JIS protection class 7)
  • Multiple available specialty eyepieces
  • Quick-aiming sightline aids in object locating
  • Sliding, rubber armored sunshade (with 95mm filter thread) shields objective from rain and stray light
  • Easily adapted to SLR cameras, digital point & shoot cameras, and video cameras with optional accessories

Kowa TSN 883

A very well finished unit with sharp clear optics. And more than adequate for casual night sky observing. The PA7 DSLR adapter is very easy to install and remove and very easy to use. Overall this is a very fine product!

quality spotting scope for birding

Made in Japan. A well balanced spotting scope with quality optics. It comes with the (removable) TE-11WZ 25-60x wide-angle zoom eyepiece, which along with the 88mm objective lens brings in a lot of light. Features I purchased for include magnesium body without rubber coating, dual-speed coarse/fine focus dials, fluorite crystal objective lens. Viewing is clear and bright across the entire image.
