Antares 3x ED Twist Lock 1.25″ Barlow lens

The Antares 3x ED Twist Lock Barlow lens is a high-quality optical accessory designed for use with standard 1.25″ eyepieces. It triples the magnification of any eyepiece you attach to it, effectively doubling or tripling your telescope's range without the need to buy additional eyepieces.

Key features

3x magnification - triples the effective focal length of your telescope
ED glass (extra-low dispersion) - minimizes chromatic aberration and color fringing for sharper, clearer images
Twist Lock mechanism - securely holds your eyepiece in place without the need for thumbscrews, making it easy and quick to switch eyepieces
1.25″ barrel size - compatible with the most common eyepiece size used in amateur astronomy
High-quality anti-reflection coatings on all optical surfaces for maximum light transmission

Why choose an ED Barlow lens?

Standard Barlow lenses can sometimes introduce false color (chromatic aberration) around bright objects such as planets or the Moon. The use of ED (extra-low dispersion) glass in the Antares Barlow significantly reduces this effect, producing images with better contrast and true color rendition. This makes it an excellent choice for planetary observation and astrophotography.

Twist Lock - simple and reliable

The Twist Lock system replaces the traditional thumbscrew that is typically used to hold an eyepiece. You simply insert the eyepiece and twist the collar to lock it securely. This reduces the risk of scratching the eyepiece barrel and makes it faster to change eyepieces during an observing session.

Who is this Barlow lens for?

This Barlow lens is suitable for both beginners and more experienced amateur astronomers who want to get more from their existing eyepiece collection. It is especially useful for observing the Moon, planets, and double stars, where higher magnification and image clarity are important.
