Kowa TSN-88S PROMINAR Straight Spotting Scope

KOWA TSN-88S PROMINAR Straight Spotting Scope

The Kowa TSN-88S Prominar is a straight-view nature spotting scope with an 88 mm front lens made from pure fluorite crystal. It is ideal for birdwatching and observing other aspects of nature, as well as for digiscoping, where colour reproduction and detail are of the utmost importance.

Fluorite optics and coated prism

A convex fluorite crystal front lens, combined with a concave lens, eliminates chromatic aberrations and brings out details that were previously invisible. The optical coating has been applied not only to the lenses but also to the prism, which improves light transmission and makes the colour reproduction broader and more true-to-life than in the previous model. For example, more shades are now visible in the dark plumage of a bird than before.

Protected front lens and durable frame

The 95 mm filter thread integrated into the body eliminates the gap between the front lens and the filter, which reduces the amount of dirt reaching the lens and prevents reflections. Kowa’s KR coating repels dirt, moisture and dust. The barrel is made entirely from a magnesium alloy, making the lens lighter and more durable than the previous TSN-880, and its design is based on the ergonomics of the TSN-99 series.

Dual focus and an extensive range of accessories

In the dual-focus system, the quick-focus mechanism locates the subject in just a few turns, whilst the fine-focus mechanism fine-tunes the sharpness with fingertip precision. The accessory collar and bayonet mount are fully compatible with Kowa System accessories, such as the 25–60x TE-11WZ II and 35x TE-80XW eyepieces, the EX-16 1.6x extender and digiscoping adapters. The earlier TSN-880 and TSN-770 eyepieces are also compatible, and with an astronomical eyepiece, the scope can also be used for stargazing.
