Vixen 103mm SD Apochromatic Refractor Telescope Tube – Sharp, Color-Free Views for Astrophotography & Deep Sky Stargazing (ES26147)

A Premium 103mm Apochromatic Refractor for Deep-Sky and Planetary Observing

The SD103S is a 103mm apochromatic refractor using Vixen's SD glass — premium glass that virtually eliminates color fringing and delivers sharp, true-color images across the full field. At 795mm focal length (f/7.7), it's well-suited for both wide-field deep-sky targets and detailed lunar and planetary views.

The tube comes fully equipped with a flip-mirror diagonal, illuminated finder, dovetail plate, and tube rings with carry handle — ready to mount on a compatible equatorial or alt-az mount.
