Kowa enjoys a spectacular reputation of enduring quality internationally, where there are large numbers of nature enthusiasts.

Kowa's 66mm series employ the great features of their world class flagship model, the TSN-821 M, in a smaller scope. Despite having a larger front element than two well-known 65mm scope competitors, the heaviest of the Kowa versions is still lighter than the lightest of their European brethren.

It is entirely a matter of personal preference best determined by experience, but many feel that angled scopes offer a more comfortable position for extended viewing periods. They're usually a bit easier to share amongst multiple users of varying heights as well.

The TSN-663 uses an element of ED(extra-low dispersion) glass in its construction, which greatly minimizes chromatic aberration. Most spotting scopes are essentially refractor telescopes built for harsh abuse, with permanently included prisms to render the terrestrial world upright and laterally correct. For all their contrast and resolution, refractor telescopes did fall out of favor with astronomers for their false coloring at the image periphery(chromatic aberration).

This problem becomes more prevalent the larger and longer the refractor is and is easily seen in astronomy-but much harder to detect in birding, for example. But if you view a bird in front of a bright sky background with a normal scope, you'll see some fringing on the edge of the subject where it meets the sky in your view. This may appear as a blue or purple hazy line. Glass with ED elements greatly reduce this effect.

Full multicoatings on all lenses and prisms
360° rotating base with click stops allows usage from many angles-even overhead
Quick-aiming sightline aids in object locating
Sliding sun shade shields unnecessary light and raindrops while providing protection for the front element (which has a 72mm filter thread)

Adaptable to 35 mm SLR cameras, digital cameras, and video cameras with optional photo adapter
Metal alloy & carbon fiber rubber-armored construction
Objective Lens Diameter 66mm
Minimum Focus Distance 19.7' (6.0 m)
Weatherproofing Waterproof & fogproof
Dimensions 12.2" (311mm)
Weight 2.29 lb (1040 g)

          Comments about Kowa TSN-663 2.6"/66mm Spotting Scope with Flourite (Requires Eyepiece):

          I bought this spotting scope to use for scoring in long range shooting. This requires a spotting scope to be able to clearly resolve bullet hole makers placed on a target face at ranges out to 1000 yards.The spotting scope needed to be light and portable and the 66 mm Kowa TSN-663 was around the right dimension and weight. I decided the Flourite glass was needed for the best light transmission and image resolution.So much for the theory of selecting the Kowa scope, how did it shape up under use in the field? I am pleased to say the image quality thru both the 20-60 zoom and the 30X wide eyepieces that I purchased with it is simply outstanding! On cooler days, (I live in Australia) that are mirage free the image is like standing directly in front of the target as the scope compresses the distance so well.I also take the scope slightly out of focus to view the mirage on hot days to get an indication of the winds activity. This spotting scope does everything I want and provides a very bright and well resolved image. Its that good I have just ordered a camera adapter for it to use with my Canon G12.One drawback with this scope is that you must purchase a protective cover/carry case for it. I think for the price maybe Kowa should have included one in the box with it.The purchase of this spotting scope has been a very positive experience [...].The outcome of my experience is that I would definitely recommend the Kowa TSN-663 to anyone looking to use it for long range target shooting.
