Imagine standing under a perfectly clear sky, ready to explore the vastness of space with absolute clarity. The Explore Scientific 68° Series 2" 28mm Waterproof Eyepiece is designed to elevate your stargazing experience, offering an expansive 28mm focal length that captures wide, breathtaking views of galaxies, nebulae, and star clusters. With a 68° apparent field of view, you’ll feel fully immersed in the night sky, taking in celestial objects with unparalleled detail and sharpness.
This eyepiece uses fully multi-coated optics and low-dispersion glass, ensuring that every detail is sharp, clear, and vibrant. These coatings minimize glare and maximize light transmission, so you can view faint stars and distant objects with precision. Whether you're observing the delicate filaments of the Orion Nebula or the spiraling arms of the Andromeda Galaxy, the image quality remains crisp from edge to edge, eliminating the need for constant adjustments or worrying about blurring at the periphery.
Built for the elements, this eyepiece is argon-purged, making it both waterproof and fogproof—so you can observe even in the most challenging weather conditions. Argon’s large atomic size prevents moisture from seeping in, ensuring that the lenses remain free from condensation, which is essential when you're observing for long periods in fluctuating temperatures. Whether you're in a humid forest or under chilly mountain skies, your views will stay crystal clear.
Comfort is key during extended viewing sessions, and this eyepiece delivers with a generous 21.6mm eye relief and a fold-down eyecup. These features are particularly beneficial for eyeglass wearers, as they allow for comfortable, strain-free viewing without compromising the field of view. Plus, the eyepiece is designed with a textured, slip-resistant surface, providing a secure grip—even in cold or damp conditions.
One of the standout features is its parfocal design, allowing you to switch between eyepieces without needing to refocus. This saves time and makes your observing sessions more efficient and enjoyable, letting you seamlessly explore the night sky without the frustration of adjusting focus between different magnifications. This eyepiece is also compatible with most 2" diameter focusers, making it a versatile addition to your astronomy toolkit.
By choosing the Explore Scientific 68° Series 28mm Eyepiece, you’re investing in an experience, not just a product. It’s for the serious astronomer who values sharp, wide-field views and needs reliable equipment that performs consistently under any condition. Whether you’re out in the field on a solo deep-sky observation or leading a group stargazing session, this eyepiece will be the one you reach for, time and time again, to bring the wonders of the universe into perfect focus.
