The gray, straight viewing TSN-664 66mm Spotting Scope from Kowa features high-quality optics built into a body that is designed for reliable use under a variety of viewing conditions. Measuring 12.3" long and constructed from magnesium alloy, this durable scope can provide a wide angle or a versatile viewing range depending on which separately available eyepiece is installed on it.

Compatible Kowa eyepieces include the TE-14WD 30x Wide Angle Eyepiece, the TE-17HD 25x Long Eye Relief Eyepiece, and the TE-9Z 20-60x Zoom Eyepiece.

While in use, the TSN-664 66mm Spotting Scope's PROMINAR XD (eXtra-low dispersion) Lens and a concave dispersion lens work together to minimize chromatic aberrations. Additionally, multicoated optical surfaces help to consistently maximize light transmission, sharpness, and color fidelity.

A nitrogen fill prevents fog accumulation and an O-ring sealed waterproof construction further add to the rugged design of the TSN-664 66mm Spotting Scope. Conforming to JIS (Japanese Industrial Standard) Protection Class 7 waterproofing, this scope can withstand momentary immersion, assuming the eyepiece mount is not open and exposed.

        Comments about Kowa TSN-664 66mm Spotting Scope (Straight Viewing, Gray):

        High quality optics in a lightweight portable package. I am very impressed with the quality of this product. Construction is first rate and very solid with good ergonomic features. The optics are amazing with no color fringing or distortion. I use the scope with a KOWA TSE-Z9B 20-60x eyepiece, another quality item.

        I am amazed every time I use this scope at the distances I can see, with such detail! I can spend hours looking through the scope enjoying all the detail that has been hiding in plain sight. You can even get photos using and iPhone held up the eyepiece… The image is surrounded by a black circle but the detail is amazing.

        I would recommend the CNW-10 Kowa Cordura Carrying Case. The case is great and is very fast to open and offers protection from bumps and scrapes. You will also need a solid tripod and head as any vibration is easily seen at the high magnification this scope is capable of.
