Kowa TSN-66S PROMINAR Spotting Scope

KOWA TSN-66S PROMINAR Spotting Scope

The TSN-66S is a straight telescope from Kowa’s Prominar range, combining a 66 mm objective lens with fluorite crystal optics. It is ideal for birdwatchers and hikers who want a sharp and clear image without the weight of a large telescope. See also accessories for binoculars and telescopes.

Fluorite optics, as with larger tubes

The TSN-66 utilises optical solutions developed for the larger TSN-88 and TSN-99 models. The fluorite crystal lens and improved coating allow light to pass through efficiently across the entire visible spectrum, and the image is free from chromatic aberration. The KR coating on the front lens repels dirt, moisture and dust.

Dual focus and weather-sealed body

Quick focus brings the subject into focus in just a few turns, whilst fine focus allows you to adjust the sharpness precisely with your fingertip. The magnesium alloy body is fully sealed, 100 per cent waterproof and nitrogen-filled. The twist-up sunshade features a sighting aid that helps you find your subject more quickly.

Compatible with Kowa System accessories

The accessory collar and bayonet mount are compatible with the entire Kowa System range of accessories. The TSN-66S is the straight version, and an angled version, the TSN-66A, is also available in the same tube.
