Rapid target acquisition and intuitive handling – the KOWA TSN-502 with straight-through eyepiece
The KOWA TSN-502 Spotting Scope 20-40x50 with straight-through viewing is the perfect choice when you need to locate targets quickly and start observing immediately. The straight eyepiece makes aiming at a subject intuitive – simply point, look through and observe. Sharing identical optics with the sister model TSN-501, the TSN-502 delivers the same multi-coated image quality in a 400 g and 259 mm compact body. KOWA, Japan’s optics manufacturer since 1894, offers an accessible entry-level spotting scope without compromising on fundamental optical quality.
Straight-through · Fast Target Acquisition
Straight-through viewing – target in sight without tilting your head
Unlike angled eyepieces, the straight-through design of the TSN-502 provides a direct line of sight from eye to target. You spot the subject with the naked eye, align the scope and look straight through – without changing your viewing direction. This method is particularly fast and intuitive, making the TSN-502 ideal for observing rapidly moving subjects. The straight design is also optimal for digiscoping, as camera and scope share the same optical axis.
Multi-coated glass optics – high-contrast images for beginners and experienced observers
The multi-coated lenses of the KOWA TSN-502 deliver bright, high-contrast images with accurate colour reproduction. The coating reduces stray light and reflections, providing usable images even in backlit situations or at twilight. The 50 mm objective gathers sufficient light for most outdoor observation scenarios.
Waterproof and fog-proof – nature observation in any weather
Nitrogen filling and full sealing keep the KOWA TSN-502 fog-free even during rain, mist and temperature swings. The 55 mm filter thread accepts protective and polarising filters.
