The largest aperture model of the ED series, the ED115S is a 115m APO refractor using Vixen’s latest ED glass for low chromatic aberration and sharp images across the field of view.

The large aperture provides for 270x light gathering power yet the telescope tube is a compact 940mm long and weighs under 5kg making it suitable for portable observation set-ups.

The Vixen ED series refractors are made in Japan. As with the other models in the range, the ED115S includes an integrated dew shield, dual speed focuser tube rings and dovetail mounting plate.
