30 mm - 82º Argon-Purged Waterproof 2" Eyepiece - EPWP8230-01

This 30mm Explore Scientific eyepiece delivers an exceptional 82-degree apparent field of view combined with 22mm of eye relief, making it ideal for wide-field deep-sky observing and extended viewing sessions. Featuring fully multi-coated optics with computer-designed low dispersion glass and enhanced multilayer deposition (EMD) coatings, it produces high-contrast, sharp images across the field with superior flat field characteristics. The 2-inch barrel is argon-purged and waterproof, providing reliable performance in any weather condition, while the long eye relief and ultra-wide field make it excellent for both naked-eye viewing and eyeglass wearers observing nebulae, star clusters, and comets.
