Sky-Watcher 2x ED Barlow lens Wide-angle Zoom Lens  (Black, 0)

This unique product is made to cut cost and simply for convenience. It doubles any eyepiece placed into it without the need to purchase more eyepieces. It also helps to obtain high powers with longer focal length eyepiece for comfort. The ED Barlow lens is compatible with all 2” and 1.25” eyepieces and improves their performances significantly, especially when used on telescopes with short focal length. Its “three Element” design brings superior color correction and higher-power observing, in comparison with the “two Element”. Though best suited for ED refractors and Newtonian Reflectors, this product can be used on any OTA.
