After 14 years of designing binoviewers and peripheral optical systems to allow focus, power switching, filter switching, and collimation, Denkmeier decided to create the perfect binoviewer from scratch. They built the body, machining, and all optics to the highest tolerances. Focus is no issue in ANY telescope with this system.

Included is the Binotron-27 Super System with rubber-coated body and individual focusing eyepieces that move each eyepiece up and down, not around. You can fine-tune the diopter adjustments without the eyepieces rotating.

Compared to many other binoviewers on the market, the Binotron 27 allows for quick and easy touchup of collimation in under a minute. Note that every Binotron is collimated to the most exacting standards so you may never need to consider doing the collimation adjustment but if it ever becomes necessary, this can be accomplished in seconds.

The included OCS (Optical Corrector System) consists of a dual-arm power switch attached to the Binotron which produces three different magnification factors with a single pair of eyepieces. A 2" nose section, a Middle Newtonian Spacer Tube (required only for Newtonian use), and the OCS A37 optical cell (required for Refractors and Newtonians but not for SCTs) is also included. 

The Denkmeier Binotron 27 Super System also comes with an aluminum carry case with custom foam inserts. 

What other Binoviewer system out there can do so much with such high-quality performance? Answer: NONE!
