 GLASSPATH CORRECTOR 1,7x FOR MAXBRIGHT® II AND MARK V BINOVIEWERS

The Baader Glasspath Compensator/Corrector may be useful for binoviewing with refractor or Newtonian telescopes. Unlike other viewers, this corrector is not just a Barlow or other simply aplifier lens!

These proprietary multi-coated doublet compensators were specially designed for astronomical binoviewers by Carl Zeiss and AstroPhysics to actually compensate for the chromatic aberration, or color fringing, that exists in all binocular viewers, as well as the spherical aberration caused by binoviewers (from the long lightpath through the glass in the prisms). In addition to correcting these color and spherical errors, the Baader Glasspath Compensators also reduce the amount of telescope back-focus (in-travel) needed by extending the focal point of the telescope. This is especially critical in reflectors and many refractors.

A secondary benefit of the compensator is to provide additional magnification - ahead of the binoviewer. For high magnifications (ie, planetary observation), it is generally preferable to magnify the image before the binoviewer, rather than to use shorter focal length eyepieces.

It is also less expensive to purchase an additional compensator (to provide additional magnifications), rather than to purchase additional sets of eyepieces. We recommend first choosing the lowest powered compensator that will allow your scope to reach focus. This will permit the widest possible fields of view. In addition, one or more higher powered compensators can be added to give a greater range of magnifications.
