Denkmeier - Standard Binoviewer  (w/o case)

                                     Meticulous Quality Control defines all Denkmeier Binoviewers "

  • The Denkmeier Standard Binoviewer has emerged as the most popular Binoviewer in the industry.
  • Denkmeier Standard Binoviewers have superb optical quality for Planetary, Lunar, Solar and Deepsky use.
  • Every unit is Hand Collimated to ensure amazingly sharp stellar images.
  • Included SCD (self-centering diopter) eyepiece holders are CNC machined of anodized aluminum.
  • Individual eyepiece focus can be accomplished smoothly and with great accuracy.
  • Every Standard Binoviewer is available as part of a package:  Std SCT Package, Std Newtonian Package, and Std Refractor Package.
  • The Denkmeier (OCS)™ Optical Corrector System has allowed access to low-power views of the sky with TWO EYES ! 




The SCD (self-centering diopter) eyepiece holders (shown above) are CNC machined of anodized aluminum. They are self-centering for proper merging of the images. A twist on the holder collar collapses an internal split ring evenly around the 360° circumference of the eyepiece barrel. This centers each eyepiece in the light path and holds it in place without scratching, and without the use of an easily-lost thumbscrew. Individual focusing of each eyepiece is accomplished by rotating a second collar on each eyepiece. This raises and lowers the eyepieces to change the focus in either or both eyepieces, the same way the diopter adjustment on a binocular corrects for differences in your vision. The interpupillary distance extends from 50mm to 75mm, a wide enough spread to accommodate virtually any eye spacing, even that of children.

If more than one telescope is being used, corrector components may be added to allow use with all of your telescopes meaning that each telescope design will benefit from an optical peripheral device to allow the Binoviewer to work at a variety of powers.

The “Standard SCT Package” contains the SCT Richfield Star*Sweeper. This allows an F/10 SCT to also operate at F/5 with The Denkmeier Binoviewer.

The “Standard Newtonian Package” allows any Newtonian Telescope as well as Maksutovs, Cassagrains, and a variety of other reflector designs to operate at powers as low as 1.2X and also at 2.5X.

With “Standard Refractor Packages”, your refractor and Denkmeier Binoviewer with OCS for refractors will focus at powers as low as 1.2X and as high as 3X.

 All OCS accessories included with Standard Packages are in a 1.25” format. The OCS included with Standard Refractor Packages will allow the 1.25” OCS to be installed into a 2” diagonal with included “Part T” adapter.

Product Series

The Standard Binoviewer With SCD Holders

As with all of our binoviewers, this model is assembled in our Maryland, U.S.A. facility and undergoes meticulous quality control measures all along the way. We hand collimate each and every unit and check the diopters for motion and feel. Our internal lubricant is rated for smooth motion from +120 to -120 degrees Farenheit so those customers in Norway, Canada, Alaska, Sweden and all pounts north need not worry about locking up. That goes for the interpupillary motion as well.

The photo above shows the SCD Holders. Notice that they are set at different heights. The allow individual eyepiece focus to be accomplished smoothly and with great accuracy. We spent many months designing and testing the threads until we got it right! The SCDs are extremely well received by customers all around the world. The special internal threads allow focus change at a very nice speed. What we mean by this is that focus changes are easy to detect but not too slow or fast. Merges is maintained because the machining of the SCD holders is specified at very high tolerances. The top ring (black) locks the eyepiece in the holder by collapsing an internal split ring. After this is done, the silver lower ring may be used to change focus in either eyepiece. These holders are made from quality aluminum material and then clear anodized and black anodized. These are not plastic!

Uniform Fittings

All of our binoviewers will accept any Denkmeier accessory that we make. If you are purchasing a Denk Power x Switch Star Diagonal and are deciding on a model of Binoviewer, this is a very economical choice. No Power x Switch or Optical Corrector System is needed in that situation. Just load this Standard Binoviewer with SCDs in the diagonal and you are ready to Power Switch. See our Star Diagonal section for more information.

A 1.25" nose-piece is included. If you are planning on purchasing one of our Power x Switch Star diagonals, this is a great choice in a middle price range.
