Each of the four elements in SV216 is fully multi-coated enhanced coatings, resulting in bright, sharp images. the lenses are edge-blackened to eliminate internal light scatter to maximize image contrast.
Provides excellent control of chromatic and spherical aberration, and a flatter field-of-view compared to standard barlows.
Comes in a beautiful Bolt Cases box. Includes one dust plug and one end cap.

Increase Your Magnification Without Sacrificing Magnification Factor or Eye Relief: When using a barlow to increase magnification, get to enjoy the generous eye relief of the lower power eyepiece, especially for eyeglass wearers or for those with fast telescopes. The distance is changed, the magnification remains the same. Can place barlow anywhere along the optical chain between an eyepiece or a camera.
Tapered Barrel for Extra Security: The insert barrel of each extender is double-tapered to allow smooth insertion to, and removal from, a telescope's eyepiece holder, focuser or diagonal, however the wide dimension of the taper helps prevent the focal extender from falling out of the telescope should the set-screw holding it in place become loose.
