OVL Binoviewer (with 2x Barlow Lens)

This binoviewer is designed to fit into a standard 1.25 inch eyepiece tube. The binocular attachment has high quality BaK-4 prisms for clear, sharp images. This is a useful accessory for your telescope which helps to reduce eyestrain. The binoviewer comes with a specially designed 2x Barlow Lens which doubles the magnification of the eyepiece used. Comes in an aluminium case. This new BaK-4 prism version is suitable for both refractor and reflector telescopes. Please note two eyepieces are required – these are held in the binoviewer by means of compression ring adaptors designed to centre the eyepieces without marking the barrels.
