Antares 2x Apochromatic 3 element Barlow lens to fit 1.25” eyepieces.

The three element airspaced optical design of this barlow is identical to the Celestron Ultima 2x Barlow and is manufactured in Japan.

This high-performance Antares Barlow features large 27mm-diameter optical elements (great for use with a wide range of eyepieces) and a fully multi-coated apochromatic design with edge-blackened lenses for maximum contrast. The 'short' design ensures that it will work with star diagonals. In our tests it seems to be parfocal when used with most eyepieces in our collection (and that’s a pretty varied bunch!). This Barlow is ideal for use with low-powered (long focal length) eyepieces to deliver higher powers, but with maximum eye-relief and viewing comfort. It is also very useful for webcam imaging and other astro-photographic applications.

This super-quality Barlow achieves high-powered views with highest standard of colour correction – ideal for planetary and lunar observing.
