Tele Vue Eyepieces ETH130 Editorial Review
The Tele Vue 13mm Ethos eyepiece with a 100-degree field of view is made in Taiwan. It fits both 1.25 and 2-inch scopes and works very well with the Celestron Nexstar 4SE telescope. It is not the best choice for digiscoping but is optically close to perfect. The eyepiece is heavy and can cause standard focusers to slip, so you may need to upgrade focusers. The eyepiece serves as a perfect 'finder' eyepiece for medium magnification DSOs, yielding 92X magnification at just under 1.1 degrees of true FOV. Pairing this eyepiece with a longer focal length eyepiece and a few shorter focal lengths completes a set nicely. The eyepiece is an expensive investment, but worth it with its top of the line quality.
