With the Kowa Prominar TSN-66S Spotting Scope (straight), there is no need to compromise on image quality. The TSN-66 models gather 44% more light than the TSN-55 models, allowing for extended use even in deteriorating light conditions. The compact size and manageable weight (1.52 kg) meet the excellent image quality characteristic of the Prominar family.
The 66 mm objective lens spotting scopes allow for easy observation of distant targets and the study of finer details even in gloomy lighting conditions. They are an ideal choice for birdwatchers, rangers, hunters, sport shooters, or any discerning nature enthusiast. With optional accessories, they can also be used for nature photography, and with the appropriate adapter, they can accommodate 1.25" astronomical eyepieces.
Every lens element of the spotting scope is multi-coated, and the prism has a special coating, resulting in images that are even more contrast-rich, exceptionally beautiful, and bright, with subtle shade differences being more easily recognizable. The spotting scope containing an XD lens (fluorite crystal) offers virtually color error-free (chromatic aberration-free) imaging. Its dual-speed focuser allows for very precise focusing.
The nitrogen gas filling protects the scope from internal fogging even with rapidly changing temperatures, and it could even be submerged in water for a few seconds, as its sealing prevents water ingress. The Kowa Prominar TSN-66S spotting scope (45°) is completed by the included 25-60x zoom eyepiece. Thanks to the 17 mm eye relief, the eyepiece can be comfortably used even with glasses.
The high magnification of the spotting scopes necessitates the use of a tripod (it is recommended to acquire one), for which the base of the scope has two 3/8" standard tripod threads for attachment, along with two 3/8"-1/4" adapters.
