Mounted in an aluminum barrel. The lens elements can be easily removed (if you want) by unscrewing the retaining ring. An incredible price that may not last long!! NEW! This objective will make a quality refractor scope or an awesome binocular telescope if you get two. The larger the diameter of the objective, the more light that gets captured and the more you will be able to see. Wollensak brand. Quality optics since 1899.
