Your Source for the Finest in Telescope Accessories, Eyepieces, Oculars, and Telescope-Making Equipment!

An optical "expert" once made the statement that making bino-viewers isn't rocket science.  Well, he was wrong.  If the viewer is not correctly collimated and the eyepieces not correctly indexed, your vision is going to feel like an exploding Saturn booster!

We first offered binocular viewers nearly twenty years ago, so I don't think anyone has more experience with these devices.  Since man is endowed with binocular vision, a viewing system allowing the use of both eyes offers distinct advantages over a monocular tube.  Since both eyes are open and the facial muscles relaxed, visual acuity is at its peak.  You also enjoy the feeling of additional depth of field.
 

For those of you wanting to get started with binocular viewing at a very reasonable price, we offer the MK-20.  It features fully multi-coated BAK-4 prisms and individual eyepiece diopter adjustments.  Nice 20mm clear aperture.  Straight-through viewing angle.  In addition:  we will include a certificate of collimation from our Takashashi based parallel light colliminator.  We are also including a free foam lined aluminum storage case.

As to eyepieces, while some are "throwing" in two "throw away" oculars, we would like to offer you a special deal on two (2) Abbe Orthoscopic eyepieces made for us in Japan.  Over the years we have sold thousands of these and binocular viewer users report they are the "gold standard."  These will be indexed to your viewer in regards to right or left side, as well as degree of rotation.
