    Explore Scientific: With its particularly long eye relief of 15.9mm, the 4.5mm LER ocular from Explore Scientific’s 82° Series of Argon-Purged Waterproof Eyepieces puts the focus on a comfortable viewing experience for all observers. A long eye relief is especially important for eyeglass wearers because it allows them to enjoy the full field of view.


    The 4.5mm focal length is perfect for observing objects that would benefit from high magnifications such as the Moon, the planets and binary stars. When atmospheric conditions are almost perfect, this eyepiece can reveal planetary details that will are truly stunning. The 4.5mm size is also great for detailed examinations of the structures within deep sky objects like nebulae.


    This multi-element eyepiece achieves superior light transmission with edge-blackened optics made of low-dispersion glass with a high refractive index. Each lens also is fully multi-coated with durable enhanced multi-layer deposition (EMD) coatings. The combination of these factors maximizes the potential of your telescope to capture the celestial wonders you seek with sharp contrast, high resolution and crisp definition.


    Like the others eyepieces in Explore Scientific 82° Series, this ocular has an ultra-wide 82° apparent field of view that immerses observers in the cosmos and naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize that were not revealed at first glance. The broad field of view promotes the use of averted vision, which involves looking slightly to the side of a target object rather than directly at it. This is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.


    All Explore Scientific Waterproof Eyepieces are gas-purged and O-ring sealed to create a waterproof environment that is impervious to internal fogging and prevents contaminants like fungus and dust from entering the ocular housing. This design makes cleaning the eyepiece a breeze.
