The perfect binoviewer!
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 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 Denkmeier 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.
What other Binoviewer system out there can do so much with such high quality performance? Answer: NONE!
