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.
Please note that using a filter with this scope may prevent use of the built-in lens hood.
Construction Details
- Proper functionality of the retractable sunshade is guaranteed exclusively with Kowa brand filters
- 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
Optical Performance
- Spotting scope only, optional eyepiece required for proper use—compatible with TE-80XW & TE-11WZ II eyepieces
- Front XD lens is made from extremely low-dispersion glass and the secondary is made from fluorite crystal glass, creating an optical path free from chromatic aberrations (even at high magnification) with high contrast and crisp clarity
- 99mm objective lens delivers outstanding low-light performance with exceptional detail
- Antireflection 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
- Lens hood has a built-in aiming sight as a visual aid to assist in finding a subject more rapidly
