William Optics Binoviewers with accessories

William Optics Binoviewers with accessories: two eyes see more than one

With the William Optics binoviewer, you view through your telescope with both eyes simultaneously. That is more than comfort: your brain combines two images into a calmer, more detailed whole with a surprising sense of depth. The difference is especially significant on the moon and planets, and long sessions are considerably less tiring.

The BAK4 prisms and fully multi-coated optics keep both light paths bright and sharp; the compression rings clamp the eyepieces scratch-free and precisely.

Supplied complete

The set includes two 20 mm eyepieces with a 66-degree field of view and a 1.6x Barlow lens. That Barlow is more than a magnifier: it extends the light path so that the binoviewer comes into focus on most refractors and catadioptrics.

Which telescopes

Suitable for refractors, Schmidt-Cassegrains and, with the included Barlow, many Newtonians. The binoviewer requires extra focus travel; the 2x binoviewer Barlow from the range provides an extra route if the range is tight.

Included

• Binoviewer 1.25 inch with compression rings
• 2x 20 mm eyepiece (66 degrees)
• 1.6x Barlow lens
• Storage box

Featured accessories

The standalone 2x Barlow for binoviewers provides extra magnification and extra focus travel on tight systems.

For whom yes and for whom no

• ✓ Moon and planet observers seeking comfort and detail
• ✓ Who want to watch long sessions without eye strain
• ✗ Whoever mainly observes faint deep-sky objects: a light path shared between two eyes costs brightness
