This 140mm refractor has a fast focal ratio of f5.4. Deep sky objects are easily visible and astro-imagers looking for a fast instrument will be impressed with the NA140’s performance.

The advanced 4-element objective lens, set in two groups, minimises residual chromatic aberrations. With its Petzval-like correcting lens at the rear, this neo-achromatic telescope is specifically designed to provide improved colour and a flat field, making it well-suited to astrophotography.

The tube weighs under 7kg and has a focal length of 800mm. There’s a built-in dew shield and Vixen’s dual speed focuser is supplied as standard together with tube rings and dovetail mounting plate.
