An Unmatched 120° Field of View
The 120° Series 9mm Waterproof Eyepiece delivers an apparent field of view unlike anything else in visual astronomy, immersing the observer in an expansive window on the night sky.
The hyper-wide field keeps objects in view far longer, making this eyepiece an outstanding match for unmotorized telescopes like Dobsonians, where wide fields mean less frequent repositioning.
The expansive view also makes averted vision technique effortless, helping observers tease out the faintest deep-sky detail while still delivering close-up, detailed views of planetary and lunar targets.
