Explore Scientific 4.5mm 52° Series Argon-Purged Eyepiece
Precision optics and comfortable viewing come together in the Explore Scientific 4.5mm 52° Series Eyepiece, delivering high-contrast planetary and deep-space performance at an affordable price. Whether you’re observing the intricate cloud bands of Jupiter, resolving the Cassini Division in Saturn’s rings, or tracking down distant planetary nebulae, this eyepiece provides a crisp, immersive experience for high-magnification viewing.
A Refined Optical Design for Exceptional Clarity
The Explore Scientific 4.5mm 52° eyepiece features a fully multi-coated optical system that maximizes light transmission and contrast. Each lens element is precisely polished and coated to minimize internal reflections and ghosting, ensuring that the fine details of celestial objects remain sharp and well-defined.
With a moderate 52-degree apparent field of view, this eyepiece strikes a balance between magnification and image framing, making it ideal for planetary observation while still providing enough space to comfortably track objects through the eyepiece.
Argon Purging for Long-Term Optical Integrity
Unlike many eyepieces in its class, this model is argon-purged and O-ring sealed, offering superior protection against internal fogging and moisture intrusion. Argon molecules are larger and less likely to diffuse over time compared to nitrogen, making this eyepiece a durable choice for astronomers who observe in a variety of climates.
This sealing also protects the optical elements from dust and debris, ensuring that your eyepiece performs at its best for years to come with minimal maintenance.
Comfortable Eye Relief and Precision Engineering
Designed with comfort in mind, the Explore Scientific 4.5mm eyepiece offers excellent eye relief, making it easier to observe for extended periods, even when wearing glasses. The fold-down rubber eyecup provides flexibility for different viewing preferences while helping to block stray light for an improved observing experience.
The barrel is precision-machined from high-quality aluminum and features a standard 1.25-inch format, making it compatible with virtually all modern telescopes. A blackened interior and lens edges further reduce stray light scatter, enhancing image contrast.
Built for Performance and Value
Whether you are an experienced observer looking for a high-powered planetary eyepiece or a beginner upgrading to premium optics, the Explore Scientific 4.5mm 52° eyepiece offers exceptional performance at a price that makes sense. Its combination of high-contrast coatings, argon purging, and precision optics delivers outstanding views that rival far more expensive models.
With Explore Scientific’s industry-leading lifetime warranty, you can buy with confidence, knowing that your investment is protected.
Upgrade your telescope’s high-magnification capabilities with the Explore Scientific 4.5mm 52° Series Eyepiece—where optical excellence meets affordability.
