Svbony 3x Achromatic Barlow

This eyepiece is in excellent condition. The glass has no scratches or blemishes and there's no dust on the interior of the barlow. 

Product Overview:

• Magnification: 3x magnification, effectively tripling the power of any eyepiece it is used with.
• Optical Design: Achromatic Barlow lens, which uses two lens elements designed to minimize chromatic aberration (color fringing) while maintaining image sharpness.
• Achromatic Lens Elements: The achromatic design corrects for color distortions (chromatic aberrations) that can occur when light passes through glass, ensuring sharper, more accurate color reproduction.
• Multi-Coated Optics: Lenses are multi-coated to enhance light transmission, reduce reflections, and minimize optical distortions, providing clear and bright images.

Performance and Use:

• Triple Eyepiece Magnification: The 3x magnification greatly increases the power of any eyepiece. For example, a 20mm eyepiece will act like a 6.7mm eyepiece when used with this Barlow lens.
• Wide Compatibility: Fits any standard 1.25-inch eyepiece and telescope, making it a universally compatible accessory.
• Image Quality: The achromatic design helps to reduce chromatic aberration, which is especially important at higher magnifications. Multi-coating further improves light transmission and minimizes glare, preserving image quality even at 3x magnification.

Build Quality:

• Barrel Size: 1.25-inch standard barrel, ensuring compatibility with most telescopes and eyepieces on the market. The barrel is often threaded to accept filters (such as moon or planetary filters), so you can stack the Barlow with filters without removing it from the optical path.
• Body Construction: Made from sturdy, lightweight materials such as anodized aluminum, ensuring durability and ease of use.
• Lens Housing: The lens is securely housed to protect it from dust and damage during regular use and transport.
