Kowa TSN 663M ED angled spotting scope (66mm) + Eyepiece 20-60x + Case

Kowa presents us with a 66mm objective aperture ground telescope, angled version and with a 20 to 60X wide focus zoom eyepiece . The 663M ground- based telescope incorporates the latest generation optics with extra-low dispersion XD treatment . This treatment eliminates the chromatic aberration present in lower quality lenses and gives it an improved brightness and contrast optimized for complex viewing conditions. Besides, the 66mm lens opening gives it 120% more luminosity than 60mm models, so in low light conditions, the improvement is substantial.
The telescope is filled with nitrogen gas to prevent fogging of the lenses and is also protected from splashes according to the JIS7 protection, it is recalled that the telescope is not submersible .
The equipment is completed with the 20-60x WF zoom eyepiece also under XD optical treatment and a waterproof transport case for the Kowa 66mm models.
