Lente Barlow DO-GSO 2,5x 1,25"

A 2.5x Barlow lens that doubles the effective focal length of your telescope, delivering sharp, high-contrast views for planetary and lunar observation. Its achromatic doublet design with fully multi-coated optics ensures excellent light transmission and minimal chromatic aberration, while the 1.25-inch barrel fits virtually any telescope focuser or diagonal.

Advantages

The fully multi-coated achromatic doublet significantly reduces internal reflections and enhances image clarity. The anodized aluminum housing is both durable and lightweight, and the brass compression ring holds eyepieces securely without scratching. Blackened lens edges further suppress stray light, ensuring maximum contrast.
