Tele Vue 2x 1,25 inch Barlow-lens

The Tele Vue 2x 1.25" Barlow lens is a high-quality optical accessory designed to double the effective focal length of your telescope, enhancing magnification for detailed planetary and lunar observations. Crafted in the USA with precision engineering, this Barlow lens features a 2-element achromatic design with fully multi-coated optics to deliver sharp, high-contrast images with minimal chromatic aberration. The black anodized aluminum housing ensures durability and reduces stray light, while the internal edge blackening further improves contrast. Compatible with all standard 1.25" eyepieces, focusers, and diagonals, it includes filter threads for standard 1.25" filters (M28.5 x 0.6). The parfocal design with Tele Vue Plössl eyepieces allows for seamless switching between magnifications without refocusing. Dust caps are included for protection.
