Omegon 2x achromatic Barlow lens 1.25″
If you want to get the most out of your telescope without buying an entirely new set of expensive eyepieces, the Omegon 2x achromatic Barlow lens for 1.25″ eyepieces is exactly what you need. This simple yet highly effective optical accessory doubles the focal length of your telescope - and with it, the magnification of every eyepiece you insert into it. The result: your existing eyepiece collection immediately offers twice as many magnification options, with no compromise in image quality.
How it works
The principle is straightforward. You insert an eyepiece into the Barlow lens barrel and secure it with the side thumbscrew. The Barlow lens is then placed into the standard 1.25″ focuser of your telescope. This extends the optical path and effectively doubles the focal length of the scope.
A practical example: if your telescope delivers 90x magnification with a 10 mm eyepiece, adding the Barlow lens gives you 180x. The same applies to every eyepiece in your set - so three eyepieces suddenly become six distinct magnification steps, with no additional hardware required.
Achromatic design for sharp, colour-accurate views
The achromatic construction of this Barlow lens is an important detail that experienced observers will appreciate. An achromat corrects chromatic aberration - the unwanted colour fringing that would otherwise reduce contrast and sharpness at higher magnifications. This is particularly noticeable when observing planets or the Moon, where every fine detail matters.
Ideal for planetary webcam and camera imaging
The Barlow lens is an essential tool for planetary webcam imaging. By increasing the effective focal length of your telescope, it produces a larger image scale on the camera sensor - which translates directly into a larger and more detailed capture of planets, the Moon, or double stars. A webcam or dedicated planetary camera simply connects in place of the eyepiece, directly into the Barlow lens body, giving you both the optimal working distance and the required magnification at the same time.
Compatibility
Omegon accessories are fully compatible with all telescopes featuring a standard 1.25″ focuser, so no adapters or modifications are needed. This Barlow lens fits right in alongside any existing 1.25″ eyepieces.
