## Overview

The Agena 1.25" Starguider Dual ED Eyepiece features a 12mm focal length and a 60° apparent field of view, making it a cost-effective choice for stargazers. With fully multi-coated optics and a long eye relief of 20mm, this eyepiece ensures a comfortable and clear viewing experience. Its durable rubberized body and retractable eyecups provide optimal adjustment, while the advanced lens design enhances performance.

## Description

Agena's StarGuider Dual ED eyepieces are long eye relief eyepieces with a comfortably wide field for planetary observing that also give the sharpness, high contrast, and lack of lateral color and light scatter of the finest orthoscopic and Plossl designs. These can be used in any astronomical telescope that can accept standard 1.25" eyepieces.Unlike many more expensive eyepieces for planetary observing, the Starguider Dual ED 12mm eyepiece maintains an excellent eye relief of 20mm. With six lens elements in this unique design, this eyepiece is fully internally baffled and all internal spacers have antireflection microbaffles on their edges with flat black anodizing to reduce reflections when viewing the Moon and bright planets. Every air to glass surface is broadband multi-coated for peak light transmission and outstanding contrast on subtle lunar and planetary detail. Spherical aberration of the exit pupil is well controlled, so there are no serious blackouts or kidney-bean effects if you move your eye slightly off the axis.The eyepiece has a twist-up eyecup that can be raised or lowered to provide the eye relief you find most comfortable. This eyepiece is parfocal with other focal lengths in this series, minimizing the amount of refocusing needed when switching from eyepiece to eyepiece. It is threaded to accept standard 1.25" astronomy filters and weighs approx. 6oz. Note that the color of the trim on the eyepiece may change at any time and may not exactly match the color depicted above.
