Explore Scientific 8.5mm 82 1.25″ LER Eyepiece Wide-Field Precision Meets Premium Comfort
The Explore Scientific 8.5mm 82 1.25″ Long Eye Relief (LER) Eyepiece is designed for astronomers who demand a perfect balance of high magnification, expansive field of view, and exceptional optical quality. Whether you’re scanning the intricate surface of the Moon, tracking planets across the sky, or diving deep into the heart of a star cluster, this eyepiece offers an immersive, high-contrast view with pinpoint sharpness from edge to edge.
Explore Scientifics renowned 82-degree apparent field of view delivers a “spacewalk” experience, making it feel as if youre floating among the stars. With argon purging, premium optical coatings, and an ultra-durable waterproof housing, this eyepiece is built for outstanding performance in all conditionsensuring that your views remain crisp, clear, and free from internal fogging, even in the most demanding observing environments.
The 8.5mm focal length is ideal for mid-to-high magnification observations, striking an excellent balance between zooming in on planetary details and maintaining a wide enough field for deep-sky exploration. This makes it an extremely versatile choice for a range of celestial targets, including:
- Lunar Observing Spotting fine rilles, crater shadows, and mountain peaks with stunning clarity.
- Planetary Detail Capturing features like the Cassini Division in Saturns rings, Jupiters Great Red Spot, and Martian surface markings.
- Globular Clusters Resolving individual stars in densely packed clusters like M13 and Omega Centauri.
- Nebulae and Galaxies Framing large emission nebulae and brighter galaxies with contrast and definition.
This eyepiece provides a remarkable level of contrast and sharpness, making faint objects easier to detect while maintaining vivid, high-resolution detail on brighter celestial bodies.
15mm Long Eye Relief Exceptional Comfort for All Users
Eye relief is a critical factor when choosing an eyepiece, particularly for those who wear glasses or observe for long periods. Unlike many high-magnification eyepieces that can feel restrictive, the Explore Scientific 8.5mm 82 Eyepiece features a generous 15mm of eye relief, making it a comfortable choice for all observers.
For eyeglass wearers, the extended eye relief allows you to see the entire 82-degree field without having to remove your glasses. The included fold-down rubber eyecup provides added flexibility, allowing users to adjust their viewing position for optimal comfort and field immersion.
Argon-Purged Waterproof Design A Lifetime of Performance
Unlike traditional eyepieces that are susceptible to internal fogging and dust infiltration, this Explore Scientific eyepiece is fully waterproof and argon-purged. Argon gas provides superior long-term stability compared to nitrogen purging, preventing optical degradation over time.
With its O-ring sealed, argon-filled construction, this eyepiece is completely resistant to:
- Internal fogging in humid or cold environments
- Moisture damage from dew exposure
- Dust and debris infiltration for long-term optical clarity
This makes it a perfect choice for astronomers who observe in varying climatesfrom dewy summer nights to crisp winter eveningswithout worrying about performance loss due to environmental factors.
Advanced Optical Coatings Maximum Light Transmission and Clarity
At the heart of this eyepieces optical performance is Explore Scientifics patented Enhanced Multi-Layer Deposition (EMD) coatings, which are applied to every lens surface to maximize light transmission and minimize internal reflections. The result is higher contrast, sharper image quality, and improved color fidelity, making celestial objects appear more vivid against a darker sky background.
Additionally, the internal blackened lens edges and precision light baffles help suppress stray light, ensuring that your views remain crisp and high in contrast.
Precision Machined Build for Lasting Durability
Every component of the Explore Scientific 8.5mm 82 Eyepiece is designed with longevity and precision in mind. The solid aluminum barrel ensures durability while maintaining a lightweight balance that pairs well with all telescope types. The standard 1.25-inch barrel size makes it universally compatible with a wide range of telescopes and accessories, from refractors and reflectors to SCTs and Maksutovs.
The barrel is also threaded for standard 1.25″ filters, allowing users to enhance their views with planetary, nebula, or light pollution filters for even greater observing versatility.
