• Standard 1.25-inch or 2-inch interface compatible with eyepieces and star diagonals of mainstream telescopes. Internal tube features anti-reflection threads to suppress stray light, improving contrast.
• Compatible with 2-inch standard telescope interface, this 2X Barlow lens extends focal length well for both celestial visual observation and astronomical photography.
• Equipped with ED low-dispersion optical glass, it optimizes internal light path and reduces dispersion interference to improve celestial imaging effect.
• Fully multi-coated lens surface enhances light transmission efficiency and minimizes stray light and surface reflection for clearer viewing and shooting.
• Universal Barlow lens structure owns wide compatibility, fitting most standard 2-inch astronomical eyepieces to expand observation and photography scenarios.
• It has tight and stable interface connection, supporting easy installation and removal without extra auxiliary tools for daily use.
• Threaded locking interface for secure, wobble-free connection. Works with eyepieces and cameras for high-magnification planetary photography or close-up lunar surface imaging.
