Binotron 27 Super System

Denkmeier build 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 with rubber coated body, individual focusing eyepieces that move each eyepiece up and down, not around. The eyepiece holders allow quick and easy touchup of collimation in under a minute. Note that they collimate every Binotron 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 magnfication 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.

Denkmeier’s latest creation is The BINOTRON-27. They’ve designed this binoviewer system from the ground up, creating their own tooling, molds, and machining that integrate all of our best ideas into one amazing piece of astro equipment. Features of the BINOTRON-27 represent a continuation of the Denkmeier tradition of quality. The BV27SS Binoviewer Super System includes an A37 Optical Corrector System which is best suited to refractors and Newtonians with focal ratios slower than f/5, but is not required for SCT’s.  For refractors and Newtonians faster than f/5 consider upgrading to the A45 OCS.

  • Diopter adjusters that allow individual focus for each eye, without rotation of the eyepieces.
  • NEW Patent Pending “CollitronTM Eyepiece Holders” that allow the end user to instantly collimate the binoviewer even without a telescope!* Touch up the collimation to perfection in minutes and it will stay that way!
  • The BINOTRON-27 is easy to collimate without the need for tools or servicing by Denkmeier Optical Technicians!
  • Beautiful and lightweight rubber coatings for a very comfortable feel and improved grip.
  • 27mm Aperture Prisms for superior coating of the 26mm clear aperture prism surfaces.
  • Optional OCS-A45TM Multi-Purpose Corrector. This has the largest clear aperture lens that they could make for superior light transmission, especially in fast telescopes. Ultimate optical quality too!
  • Includes custom aluminum case with high quality laser-cut foam interior.
  • Fully machined and laser engraved caps and eyepiece plugs to match the quality of this system.

This Binotron 27 SCT Super System is specialized for both SCTs and Refractors. It INCLUDES the 2″ Quartz Mirror 1/10th wave IVB (Interlocking Visual Back) Star Diagonal. The SCT Super System also includes The Binotron 27 Body, The Binoviewer Dual Arm Power Switch for three magnification factors, and The OCS A37.  It even includes the Middle Newtonian Spacer Tube if you want to use a Newtonian. The OCS is the A37 which works for a Newtonian but is not the optimized OCS A45 which is best for Newtonians of F5 and faster.

The OCS A45 was designed due to demand! FAST DOBS  have very steeply converging light cones coming off the secondary mirror. Since the OCS Optics must go deeply into the converging cone to allow the Binotron 27 to rech focus, this is an optic that simply cannot be any larger in clear aperture and still be held securly in an anodized aluminum cell. The pictures speack for themselves. Used with the Bibnotron-27 Super System this optic grabs those outer peripheral rays missed by the OCS A37 and produces a brighter image.
