Vixen 115mm SD Apochromatic Refractor Telescope Tube – Sharp, Color-Free Views for Astrophotography & Deep Sky Stargazing (ES26148)

A Premium 115mm Apochromatic Refractor for Deep-Sky and Planetary Observing

The SD115S is a 115mm apochromatic refractor using Vixen's SD glass (FPL53) — premium glass that virtually eliminates color fringing and delivers sharp, true-color images across the full field. At 890mm focal length (f/7.7), it strikes a useful balance between deep-sky and planetary performance: wide enough for large nebulae and galaxy fields, and powerful enough for 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.
