More Info

With its incredible 110° apparent field of view, the Ethos-SX 3.7mm Eyepiece from Tele Vue offers comfortable eye-relief, distortion correction, high contrast, and excellent on-axis sharpness for planetary viewing. Use the included screw-on adapter to convert the eyepiece from a 1.25" barrel to a 2.0" barrel for larger focusers.

Combining a hyper-wide AFOV with its shorter focal length, the Ethos-SX 3.7mm delivers higher magnification for enhanced detail on deep sky objects. Its smaller exit pupil also reduces eyesight limitations. Like all Ethos eyepieces, the 3.7mm also accepts astigmatism correcting DIOPTRX diopters.
