The waterproof eyepieces in our 92°, 100° and 120° Series are ultra-wide class oculars that can make your observing experience truly immersive by revealing startling expanses of the night sky. In addition, the premium eyepieces in each of these series offer the following benefits:

• Ultra-wide views that make it easier to explore large subjects, locate objects and observe with fewer tracking adjustments

• Lenses made of low-dispersion glass with a high refractive index and fully multi-coated with durable enhanced multi-layer deposition (EMD) coatings that generate brilliant images with sharp contrast and crisp definition

• Housings that are O-ring sealed and purged with an inert gas for a waterproof environment that is impervious to internal fogging and prevents contaminants like fungus and dust from entering

• Foldable soft silicone rubber eyecups that provide the most comfortable viewing experience

• Filter thread on the backside that allows for use of moon or light filters
