Orion 2" 2x Apochromatic 3-Element Barlow Lens, 44mm Clear Aperture

The Orion 2" 2x Apochromatic 3-Element Barlow Lens features fully multi-coated lens designs that render exquisite images without introducing additional chromatic aberration. Images appear sharper and more color-correct than with standard, achromatic barlows. It is especially good for high-power lunar and planetary observing and for boosting magnification in short-focal-length telescopes. The Barrels are not threaded for filters.
