Description

Achromatic 2x Barlow Lens - 1.25"

The 2x Barlow lens doubles the magnification with any given eyepiece, without any noticeable loss in image quality.

The large lens aperture allows you to use even very long focal length 1.25" eyepieces such as the TS Super Plossl 32mm without vignetting.

Multi-coated lenses and blackened lens edges result in optimum contrast and image sharpness. In our opinion the quality is en par with many much more expensive Barlows.


This 2x Barlow lens is particularly versatile:

Visual Use - 2x
Just insert the Barlow lens between the eyepiece and the telescope and you will double the magnification. At the same time you will retain the comfortable eye relief of the longer focal length eyepiece.

Visual Use - 1.5x
Just screw the lens element of the Barlow lens directly into the filter thread of your eyepiece. The resulting magnification is reduced to about 1.5x.

Photographical Converter
Just screw the lens element of the Barlow lens into a 1.25" nose piece for your camera (e.g. TS FA 1). This turns the Barlow into a photographical converter with a factor between 1.5x and 2x (depending on the distance between lens and camera sensor).

Glass Path Corrector
Binoviewers require a long back focus distance that most telescopes do not provide. With the Barlow element you can move the focal plane further out, eliminating this problem in most cases. The effective magnification factor is about 2.6x with most binoviewers.
