This 2x Achromatic Multi Coated Barlow comes in a sleek chrome package. The two-element optics are fully multi-coated, and the edges of the lenses are blackened to cut down on internal reflections. The 1.25” barrel will fit in standard 1.25” focusers and diagonals, and the Barlow will accept 1.25” eyepieces.
A metal thumbscrew locks the eyepiece firmly in place.
