This 2.5x Barlow lens features an air-spaced, three-element, apochromatic design with fully multicoated optics. The housing is precision machined from aluminum stock and black anodized to a hard finish. The lens edges and inner barrel are blackened to provide maximum contrast. This barlow gives a bigger increase in magnification than available with common 2x barlows. Made by GSO in Taiwan.
Any barlow lens typically pushes the focus point of a telescope outwards, so there is a small chance that you may not be able to reach focus with all your eyepieces in your specific telescope.
