Designed for comfort, clarity, and wide-field precision, the Explore Scientific 20mm 62° Series Eyepiece is a top performer for low-to-mid magnification observing. Whether you're sweeping through rich star fields, targeting open clusters, or taking in the faint glow of extended nebulae, this eyepiece offers the ideal balance of field width, detail, and viewing comfort.
The 62° apparent field of view provides immersive sky coverage, while the 14.8mm of eye relief ensures comfort during long sessions—even for eyeglass wearers. Its flat-field optical design delivers edge-to-edge sharpness, and EMD-coated optics with blackened lens edges boost contrast by minimizing internal reflections.
Like all eyepieces in the 62° Series, it features a near-parfocal construction for seamless swapping with minimal focus adjustment. Argon-purged waterproofing protects the optics from fog, moisture, and contaminants, ensuring reliable performance in any environment.
