🌌 Kowa TSN‑99A PROMINAR: A premium spotting scope of the highest calibre
The KOWA TSN‑99A PROMINAR is currently the most powerful telescope in Kowa’s range and a true flagship among spotting scopes. It has been specially developed for discerning users who do not want to compromise on image quality, light transmission and detail reproduction – even at maximum magnification and in difficult lighting conditions.
🔬 Top-tier optics
At the heart of the TSN‑99A is the 99 mm pure fluorite crystal objective lens, which, in combination with a concave XD (extra-low dispersion) lens, delivers absolutely outstanding images. This combination virtually eliminates chromatic aberrations – even in difficult light and shadow conditions where other optics fail. The result is brilliant, high-contrast, true-to-life image reproduction with razor-sharp details.
🌠 Light gathering power & twilight performance
Thanks to its enormous 99 mm lens aperture, the TSN-99A gathers a particularly large amount of light – an invaluable advantage at dusk, under heavily overcast skies or in dense forests. This makes it the ideal choice for ornithologists, wildlife filmmakers and outdoor photographers who still rely on top image quality even during the ‘blue hour’.
🎯 Zoom & Flexibility
With the TE-11WZ II zoom eyepiece, the TSN-99A offers a magnification range of 30x to 70x – and the image remains sharp, bright and well-defined even at 70x. In the wide-angle range (30x), you benefit from an extremely wide field of view, which is particularly useful when observing moving subjects (e.g. birds in flight) or for surveying the landscape.
Optionally, you can also use the TE-80XW eyepiece (40×), which has been specially designed for extra-wide fields of view at high resolution – perfect for panoramic observations or quiet wildlife viewing from a distance.
🧠 Focusing system: Fast and precise
Kowa has incorporated its dual-focus system here, consisting of:
Coarse focus: for quick focusing across the entire focus range.
Fine focus: for high-precision fine-tuning – ideal for high magnification or digiscoping.
This system allows for intuitive, fast operation without losing sight of the target.
🏕️ Ergonomics & Construction
The body is made from a magnesium alloy – lightweight, extremely robust and vibration-resistant. Weighing just 1.81 kg (body), it remains portable for outdoor use, despite featuring a massive 99 mm front lens.
The slanted (angled) design allows for comfortable viewing at various heights – perfect on a tripod or whilst seated. The fully waterproof and nitrogen-filled construction reliably protects the device from moisture, dust, fogging and temperature changes – making it ideally suited for extreme weather conditions.
📸 Digiscoping-compatible
The TSN‑99A can be fully integrated into the modular KOWA system:
Adapters for DSLRs, mirrorless cameras or smartphones
T2 rings and special camera attachments
TSN-DA20, DA10, smartphone mounts, etc.
This allows the spotting scope to be transformed into a high-resolution long-range telephoto lens – ideal for nature photographers who want to capture animals from a great distance.
🛠️ Build quality & accessories
The build quality is top-notch:
Excellent sealing of all moving parts
Non-slip armour
Sun visor with privacy screen (extendable)
105 mm filter thread at the front
Compatible with standard tripod threads
Kowa neoprene protective sleeves, carrying cases, and eyepiece and objective lens caps are available as optional extras.
