==========High-concerned chemical : NoneBarrel Size : 1.25 inches (31.7 mm)Magnification : 3XType : Monocular

• 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 1.25-inch standard interface, this 3X Barlow lens effectively extends the focal length of telescopes for high-magnification astronomical observation.
• Equipped with ED low-dispersion optical glass, it optimizes internal light path, reduces dispersion interference and improves celestial imaging effect.
• With precise optical structure, it is suitable for daily starry sky and celestial visual observation in various astronomical scenarios.
• Universal Barlow lens design with wide compatibility, fitting most standard 1.25-inch astronomical eyepieces for combined use.
• It features tight and stable interface, allowing easy installation and removal without any extra auxiliary tools.
• Threaded locking interface for secure, wobble-free connection. Works with eyepieces and cameras for high-magnification planetary photography or close-up lunar surface imaging.
