92° ED Series Waterproof Eyepiece
Ultra-Wide 92° ED Views for Every Session
The 92° ED Series pairs a hyper-wide, immersive apparent field with extra-low dispersion (ED) glass optics, delivering sharper, higher-contrast views with noticeably reduced chromatic aberration across four focal lengths.
The wide 92-degree field keeps objects in view longer at every magnification, from the low-power, panoramic sweeps of the 25mm to the higher-magnification planetary and deep-sky detail of the 9mm.
Long eye relief keeps every focal length comfortable for extended observing sessions, and all four eyepieces share a 2-inch barrel for use in larger focusers.
