Stereo Binocular Viewer

Enjoy your telescope in a completely new and fascinating way — use your brain to its full capacity rather than speculating on the next, larger size telescope.

The Stereo Binocular Viewer (#93690) allows you to adapt two eyepieces to the telescope for simultaneous viewing (i.e., like binoculars). The result: a fantastic three dimensional effect when observing many celestial objects. The Stereo Binocular Viewer greatly improves contrast and definition on lunar, planetary and solar subject matter as well as on deep sky objects.

Using both eyes to view through a telescope is a new, relaxed and thrilling way to at last enjoy your observing time. When both eyes are open, your eye muscles are relaxed and you do not suffer from eyestrain.

To demonstrate just one of the effects you will see, compare an eye chart when examining your eyes. Cover one eye and read the chart to the smallest line you can see clearly. Now remove the cover over the eye, relax for a few seconds and then examine the chart with both eyes open — you can see more detail than with one eye. In addition, the brain corrects for small defects (aberrations) of the eyes when given the information from both eyes.

Beyond a 50 foot distance, pupils are nearly parallel and prevent real stereoscopic viewing. However, since our brain “knows” (due to near distance experience), we identify distant objects as three dimensional. The more experienced the observer, the more this effect will be apparent.

The optics are precision aligned and MgF2 coated. Interpupillary adjustment reaches from 53mm to 76mm. The optical head has a 60° viewing angle for a comfortable viewing position. Full 360° head rotation is provided, together with 2" sleeve and 11/4" drawtube to fit 2" Focuser and 11/4" Visual Backs of all Schmidt-Cassegrains — and also Focusers of Refractors.

The removable 11/4" drawtube features a camera T-2 thread on the Binocular side and 11/4" Filter Thread on the entrance side, to accept Celestron 11/4" Eyepiece Filters. Utilizes 11/4" eyepieces (not included). Must use two eyepieces of equal focal length and design type. Made in Germany.
