An extreme astronomical and long distance observation tool of the highest measure, the Fujinon 25x150 MT-SX Binocular is a gargantuan unit with 150mm large-aperture objective lenses and a straight-viewing design. Boasting precise resolving power and superior light condensing power, this is an ideal unit for exacting observations in specialized fields. Fujinon has applied their multilayer anti-reflection EBC coatings to each lens surface, and it is also sealed for extreme resistance to the elements.

The 25x150 MT-SX is delivered without any mounting system, but there is an optional dedicated angled mount for full time astronomical use. The 25x150 MT-SX also accepts the Polaris series of polarizing, haze, nebula, or neutral density eyepiece filters.
