New! The AC730 'AE3e' 2x and 1.5x apochromatic 3 element Barlow lens to fit 1.25" eyepieces - just £49.99 inc UK mainland p&p.

NEW This stunning three element 2x and 1.5x Barlow system delivers a high contrast colour free, apochromatic 2x and 1.5x magnification with any eyepiece or camera! Features the same superb optics used in AE's acclaimed AC710 Supreme photo-visual Barlow!

British design and manufacture with Japanese made optics

This is a great-quality 3 element Barlow at any price, but our price puts it at under £50 - the low-profile functional design makes the Astro Engineering AC730 one of the world's best quality Barlow systems.

Feature packed

It's a beautifully simple design that is ultra-functional! A large (4mm thread) stainless-steel screw holds eyepieces and camera nose-pieces securely in place. Ideally suited to the job of planet observing with a high quality telescope system. The lens works brilliantly with eyepieces and cameras as well - and is the ideal accessory for use with the wide range of short-focus APO refractors currently available.

The fully multi-coated apochromatic three-element optics provide excellent high-resolution and high-contrast images. The inter nose-piece is CNC turned aluminium - the optical barral has a clear aperture over 20mm. The eyepiece holder is machined-turned from solid aluminium and finished in black anodising. Even the dust cap is turned from solid aluminium.

Supplied in an bolt bottle storage case.

The AE3e high-performance Barlow features large 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. 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.

Our comment: Relying as it does on the tried-and-tested, and much applauded, optics and aluminium cell design introduced on the AC710 Supreme photo-visual Barlow two years ago, the AC730 Barlow achieves high-powered views with the highest standard of colour correction - ideal for planetary and lunar observing at an unbeatable price. We like the functional low-profile design and the quality of construction - its simply everything a top-notch Barlow should be and we recommend it highly.
