2X Multi-Coated Barlow Lens 1.25"

Measuring approximately 30 mm in diameter and 22 mm in height, this Barlow lens is precision-machined from aluminum alloy and weighs only 18 g — balancing mechanical robustness with minimal added load on focuser mechanisms. Its 2× magnification effect is achieved through optimised optical path geometry and two fully multi-coated glass elements that maintain high transmission across visible wavelengths. Designed specifically for 1.25-inch (31.75 mm) eyepiece barrels with M28.6 × 0.6 external threading, it installs securely without adapters or shims. Suitable for both casual stargazing and structured observation routines, including lunar mapping, double-star splitting, and planetary sketching.
