The Explore Scientific 9mm 100° Series Waterproof Eyepiece redefines immersive astronomy with a massive 100° apparent field of view, allowing you to visually float through rich star fields, track planets, or examine lunar terrain without feeling boxed in. With this level of optical design, you’ll enjoy sharp, pinpoint stars from center to edge, even at high magnification.
Ideal for Dobsonians and other non-tracking scopes, this ultra-wide design makes it easier to keep targets in view. It’s also packed with serious durability—argon-purged and waterproof, this eyepiece prevents fog, moisture, or dust from degrading your view, no matter the conditions.
With fully multi-coated, edge-blackened lenses, it offers superior contrast and brightness, making faint deep sky objects or planetary detail pop. The generous 12.5mm eye relief adds comfort for extended observing sessions and is eyeglass-friendly.
