3x apochromatic Barlow with 4 elements, multi-coated optics, brass ring clamp, 1.25" filter thread, delivered in box.
DESCRIPTION
The Tecnosky 3x apochromatic Barlow lens is designed to deliver excellent optical performance at an accessible price point. Built with four fully multi-coated glass elements, this Barlow offers sharp, high-contrast images with minimized internal reflections. Extensive bench and field testing against well-known premium Barlows has shown its performance to be on par, making it a serious option for visual and imaging use.
The aluminum housing is fully blackened and threaded internally to suppress stray light. It features a brass compression ring to secure inserted eyepieces or accessories without marring their barrels. A standard M28.5x0.6 filter thread is present for 1.25" filters.
Compact and effective, it is particularly well-suited for lunar, planetary, and high-resolution imaging applications.
