Barlow lens SkyWatcher ED Deluxe 2x, 2''

SkyWatcher ED Deluxe Barlow 2x lens is an auxiliary lens system in a tube that mounts in front of the focal point of a telescope, between the telescope and eyepiece. It increases the power of any eyepiece used with the telescope by increasing the telescope's effective focal length.

This quality achromatic Barlow lens has fully multicoated optical elements effectively doubles the number of eyepieces you own - at less cost than buying that many new eyepieces individually. Eyepiece with Barlow is easier to use because it does not change the longer eye relief typical of lower power eyepieces. But be aware that an eyepiece and Barlow combination will have a slightly (2%-4%) dimmer image and slightly lower contrast than the short eye relief/short focal length eyepiece.
