Explore Scientific 4.5mm 82 Degree Series LER Waterproof Eyepiece

Discover the unparalleled viewing experience offered by the 4.5mm LER eyepiece from Explore Scientific's 82 Degree Series of Argon-Purged Waterproof Eyepieces. Designed with a generous eye relief of 15.9mm, this high-quality eyepiece ensures comfortable viewing for all observers, including eyeglass wearers, by allowing them to enjoy the full field of view.

This versatile eyepiece, with its 4.5mm focal length, is ideal for observing celestial objects that require high magnifications, such as the Moon, planets, and binary stars. Under near-perfect atmospheric conditions, this eyepiece can reveal stunning planetary details that will leave you in awe. Its 4.5mm size also makes it perfect for detailed examinations of the intricate structures within deep sky objects like nebulae.

Crafted with innovative technology, this eyepiece features edge-blackened optics made of low-dispersion glass with a high refractive index. Each lens is fully multi-coated with durable enhanced multi-layer deposition (EMD) coatings. This combination ensures superior light transmission, enabling your telescope to capture the celestial wonders with sharp contrast, high resolution, and crisp definition.

Like other eyepieces in Explore Scientific's 82 Degree Series, this ocular boasts an ultra-wide 82-degree apparent field of view that immerses observers in the cosmos and promotes relaxation at the eyepiece. This broad field of view encourages the use of averted vision, a technique that involves looking slightly to the side of a target object rather than directly at it. This method is particularly helpful when observing faint objects, as it allows you to see fainter images by utilizing a part of your eye that is more sensitive to light.

All Explore Scientific Waterproof Eyepieces are gas-purged and O-ring sealed, creating a waterproof environment that is impervious to internal fogging and prevents contaminants like fungus and dust from entering the ocular housing. This reliable and durable design makes cleaning the eyepiece a breeze, ensuring a long-lasting and enjoyable viewing experience.
