Antares 5x ED Barlow lens Twist Lock 1.25″
Looking for a way to significantly expand what your telescope can do - without buying a whole new set of eyepieces? The Antares 5x ED Barlow lens with Twist Lock mechanism is exactly what you need. With 5x magnification, it opens up completely new possibilities for observing planets, the Moon, and double stars - all thanks to an ED (extra-dispersion) glass element that greatly reduces chromatic aberration and delivers sharp, high-contrast images.
Why ED glass matters
The ED optical element is the key feature of this Barlow lens. Standard Barlow lenses can suffer from color fringing and reduced contrast at high magnifications. ED glass minimizes these unwanted effects, keeping the image clean even under demanding observing conditions. This is especially appreciated by those who focus on planetary astronomy or observing close double stars, where every detail counts.
Twist Lock mechanism - secure and fast
The Twist Lock mechanism ensures precise and quick centering of the eyepiece with no risk of it slipping or falling out. Simply twist the eyepiece into place and it is held firmly in the correct position. No tools, no screws - just a quick, reliable connection.
Built-in filter thread and wide telescope compatibility
This Barlow lens comes with a standard filter thread, so you can screw on astronomy filters directly - lunar, planetary, and others - without needing any additional adapters. The total length of 83 mm is designed to work correctly with standard 1.25″ eyepiece barrels and does not interfere with reaching focus on most refractors, reflectors, or catadioptric telescopes.
A 5x Barlow lens with an ED element effectively multiplies the usefulness of your existing eyepiece collection by five - each eyepiece you already own becomes two.
