1.25" Barlow, 2X
1.25" 2X barlow, 27mm aperture doublet, Fully Multicoated
Antares barlows will extend the focal length of your telescope for greater magnification. By generating negative spherical aberration they correct that generated by positive eyepieces and increase eye relief. The 1.25" UB2S is a fully multicoated 27mm achromat that will double your focal length and has been specifically designed to perform off-axis with Plossl eyepieces.
