Meade 2x Barlow Multi-coated Eyepiece (Pre-owned)

This item is in excellent condition, the glass doesn't have any scratches on the glass or interior. 

Product Overview:

• Magnification: 2x magnification, effectively doubling the power of any eyepiece used with it.
• Optical Design: Barlow lens, typically consisting of 2 or 3 lens elements designed to increase magnification without significantly degrading image quality.
• Multi-Coated Optics: Lenses are multi-coated to improve light transmission, reduce reflections, and minimize internal scattering. This ensures that the images remain bright and clear, even at the increased magnification.

Performance and Use:

• Doubling Eyepiece Magnification: The primary function of the 2x Barlow is to double the magnification of any eyepiece. For example, if you use a 25mm eyepiece, the Barlow will effectively turn it into a 12.5mm eyepiece.
• Wide Compatibility: It can be used with any 1.25-inch eyepiece, making it compatible with most telescopes on the market.
• Preserving Image Quality: The multi-coated optics ensure that the increased magnification doesn't come at the expense of brightness or sharpness. It preserves much of the original eyepiece's field of view and optical clarity, although higher magnifications can sometimes lead to slightly dimmer images due to light dispersion.

Build Quality:

• Barrel Size: 1.25-inch standard barrel, ensuring compatibility with a wide range of telescopes and eyepieces.
• Body: Made from durable, lightweight metal (usually aluminum), the body is rugged enough for frequent use and transportation.
• Filter Threads: The Barlow is often threaded for filters, allowing users to apply additional filters (e.g., moon filters, planetary filters) without having to remove the Barlow lens from the optical path.
