Product Details

For observers who want to power-up their 2" eyepieces, the Antares model 2UBS barlow lens offers a 1.6x increase in magnification and reduced spherical aberration with all oculars. With a clear aperture of 41mm and a short length tube, this fully multicoated achromatic design will work with telescopes with the 2" format, including those using a 2" diagonal.

Features include rubber grip, 2-screw clamping, edge-blackened elements and internal baffling. When used with a diagonal, this barlow will provide approximately 2.4x if placed before the diagonal or 1.6x if inserted into the diagonal.

Note that the use of any optical element like barlows and focal reducers changes the focus point of your telescope, requiring additional in-focus or out-focus travel. The exact amount of focus travel required will depend on the optics and mechanics of your specific set-up (telescope, diagonal (if used), barlow, and eyepiece). Hence, be aware that you may not be able to reach focus with all eyepieces or in all configurations with a given barlow.
