Introduction:
- It adopts the classic Huygens optical design, paired with a 20mm/16mm/10mm/4mm (optional) medium length focal length, providing you with a bright and wide low magnification field of view. Whether searching for target celestial bodies or observing the massive Pleiades and diffuse nebulae, it can make the observation process easy and enjoyable. The high transmittance FMC green film and solid metal mirror body ensure clear and transparent observation experience on every starry night.
Applications:
- Star finding and navigation: Using low magnification and large field of view to quickly locate target celestial bodies in the night sky, it is the "guide" before observation.
- Deep space celestial observation: Observing large and scattered open star clusters (such as honeycomb clusters) or extended nebulae, which is more impactful than high-power telescopes.
- Landscape observation: In conjunction with astronomical telescopes, it can also be used for long-distance viewing.
Reminders:
- Applicable equipment: This product is a specialized eyepiece for astronomical telescopes and is not recommended for use in other instruments.
- Observation limitations: The Huygens eyepiece has a relatively small field of view and a short exit pupil distance, and is not recommended for high magnification planetary fine observation (it is recommended to use a Datyson PL or wide-angle eyepiece for high magnification observation).
- Optical maintenance: Optical glass lenses are fragile, please do not touch the surface of the lens directly with your hands. When cleaning, please use a special lens cloth.
Features:
- Comfortable low magnification scanning experience: A focal length of 20mm provides a large field of view, making it ideal for rapid star searching in the early stages of observation, or for providing an immersive and expansive view when observing large deep space objects such as the Orion Nebula.
- Classic Huygens optical structure: Adopting the traditional Huygens (H-type) design, the structure is simple and efficient, which can effectively eliminate coma and present you with clear celestial contours.
- High transparency FMC green film: The lens is treated with FMC (full surface multi-layer broadband) green film, which greatly improves the light transmittance, effectively reduces reflection and ghosting, and makes the star image brighter and sharper.
- Durable metal mirror body: Different from cheap plastic eyepieces, the Chixiao series adopts a precision aluminum mirror body, which is sturdy, durable, and full of texture. It also has a standard 1.25-inch (31.7mm) interface, suitable for most astronomical telescopes on the market.
