Representing the largest objective in their flagship series, the 45° angled viewing Kowa TSN-99A 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-99A 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 at a 45° angle to the body, putting the user's head in a comfortable viewing position whether they are standing, sitting, or lying prone
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
