Vai al moduloKowa TSN-AS1.25G is the official Kowa adapter that turns TSN-99, TSN-88 and TSN-66 PROMINAR spotting scopes into versatile astronomical instruments, compatible with any standard 1.25" (31.75 mm) astronomical eyepiece. Thanks to the grub screw locking system, the eyepiece stays firmly secured during observation.
The TSN-AS1.25G screws directly onto the eyepiece mount of the Kowa spotting scope, replacing the original eyepiece. Once fitted, it accepts any 1.25" eyepiece from any manufacturer — Pentax XW, Baader Morpheus, Tele Vue, Vixen and many others — expanding night-sky observation possibilities without buying a dedicated telescope. Combined with the Kowa TSN-EX16 (1.6×) extender, it lets you reach deep-sky objects.
The TSN-99/88/66 PROMINAR series is built around the Kowa System concept: an ecosystem of interchangeable accessories that turns the same optical body from a daytime spotting scope into an astronomical instrument, from digiscoping to nature photography. The TSN-AS1.25G adds the celestial dimension without compromising the optical quality guaranteed by the Kowa PROMINAR's pure fluorite crystal objective, which virtually eliminates chromatic aberration.
Anyone travelling to dark-sky locations — mountains, deserts, islands — can bring a single compact instrument for both daytime observation and night astronomy sessions. The TSN-88A with the TSN-AS1.25G and a 5mm eyepiece delivers around 100× magnification with premium fluorite optics.
