Product Description

Product Info for Kowa TSN-99S Prominar Spotting Scope (Straight Viewing, Eyepiece Required)

Representing the largest objective in their flagship series, the straight-through viewing Kowa TSN-99S Prominar Spotting Scope utilizes a combination of extra low-dispersion and pure fluorite crystal glass, coupled with optical lens coatings, to produce views free from chromatic aberrations, high light transmission, and improved color rendition, resolution, contrast, and clarity. Additional design elements include a specially designed ring and bayonet mount that allows the use of a suite of accessories and eyepieces to enhance your user experience and expand the capabilities of your scope. This version of the TSN-99S is offered here without an eyepiece, so you can choose the one that's right for you and pick it up separately.


Optical Performance

  • Spotting scope only, optional eyepiece required for proper use—compatible with TE-80XW & TE-11WZ II eyepieces
  • Front XD lens is made of extremely low-dispersion glass and the secondary is made of fluorite crystal glass, creating an optical path free from chromatic aberrations at even high magnification with high contrast and crisp clarity
  • 99mm objective lens delivers outstanding low-light performance with exceptional detail
  • Anti-reflection fully multicoated lenses maximize light transmission and improve color rendition, resolution, contrast, and clarity
  • Proprietary KR coating on the exterior of the lens actively repels dirt, moisture, and dust from collecting on its surface to ensure clear views

Use and Handling

  • Eyepiece socket is set in-line with the body to make finding subjects faster and tracking moving targets easier
  • Dual-focus system: Quick (coarse) focus allows for fast action to bring your subject in to detail in just a few smooth revolutions and Fine focus gives pin-point, finger-tip control offering precise focusing accuracy with minute adjustments possible, even when wearing gloves—increasing performance for applications such as digiscoping when accurate focus is critical
  • Eyepiece quick release button allows the eyepiece to be removed smoothly for quick eyepiece or adapter changes without compromising on a secure connection to the scope body
  • Tripod mount has a removable screw that allows the spotting scope to be attached to either 1/4"-20 and 3/8"-16 heads and quick release plates
  • The orientation of the scope can be changed with the release of a locking button for precise eyepiece placement to improve viewing comfort
  • An easily accessible collar on the eyepiece mount allows for quick connection of current Kowa System accessories, including adapters for digiscoping and a 1.6x extender
  • 105mm objective filter thread allows for a protective or UV filter to be added—the sunshade can still be used even with a filter installed
  • Lens hood has a built-in aiming sight as a visual aid to assist in finding a subject more rapidly

Construction Details

  • Compact design measures under 15" long
  • Lightweight, strong, and corrosion-resistant magnesium alloy chassis
  • Nitrogen-filled and O-ring sealed to protect from the elements—chassis is resistant to internal fogging in extreme conditions and waterproof
  • Smooth ergonomics make it comfortable and easy to use out in the field for long periods of time
  • Smooth twist-out sunshade helps to eliminate glare from the sun and reduces exposure of the objective lens to elements such as moisture, grit, and sand
