Explore Scientific 62° 14mm Waterproof Eyepiece - 1.25"

A 62° Flat-Field View for High Contrast

This eyepiece is engineered as a flat-field, multi-element system, ensuring stars remain sharp across the entire 62° view. This optical correction is critical for resolving fine detail in open clusters or tracing the faint structures of nebulae right to the edge of the field stop.

The high-contrast optics make it easier to use averted vision—looking slightly to the side of a faint object—to detect dimmer targets. This technique places the image on a more light-sensitive part of your retina, and the clean optical design of the 62° series enhances this effect for hunting down faint galaxies and nebulosity.

A 1.25" Barrel with Argon-Purged Durability

Designed for reliability in all observing conditions, this eyepiece is fully waterproof and purged with inert argon gas. This process prevents internal fogging during nights with heavy dew and permanently seals the optics against dust, fungus, and moisture infiltration.

The rugged construction ensures the eyepiece can handle the rigors of travel and years of use in the field. The standard 1.25" barrel provides compatibility with the vast majority of telescope focusers and accessories.

Explore Scientific 62° vs. a Standard 52° Plössl

Compared to a typical 50° or 52° Plössl eyepiece, the 62° apparent field of the Explore Scientific design feels noticeably wider and more engaging. While a Plössl provides a sharp center-field view, the 62° eyepiece offers a more expansive context around your target.

• Wider Context: The extra 10° of field makes it easier to frame larger objects like the Pleiades (M45) or keep planets within the field of view on non-driven mounts.
• Flat Field: Unlike many basic eyepieces that show distortion or softness at the edges, this eyepiece's flat-field design maintains image integrity across the view.
• Trade-Off: While significantly more immersive than a Plössl, the 62° field is not as vast as ultra-wide 82° or 100° eyepieces, which come at a much higher cost and weight.
