Denkmeier 2" Power x Switch Diagonal #R2 for Refractors and Binoviewers

#R2 provides tremendous versatility allowing a binoviewer to move through up to 6 different magnifications with a low 1.26X power factor to a high power of 3.2X with 4 magnifications in-between. This is because it includes two Power x Switches: one on each side of the diagonal housing. Slide out the binoviewer and slide in a single eyepiece and move through up to 7 magnifications ranging from .76 reduction to 2.3X multiplication. This diagonal can also be used for F/10 SCTs allowing focal reduction and barlowing in binoviewers and single eyepieces.

Uses of Diagonal #R2...

The R2 Diagonal has been designed to allow use of a binoviewer or single eyepiece and creates instant magnifications changes when the Power x Switch Arms are used. The observer may change from Binoviewer to single eyepiece without removing the diagonal from the telescope. There is nothing to unscrew or remove from the diagonal when moving between binoviewer and single eyepiece use. R2 provides up to 7 varying magnifications when using a single eyepiece and up to 6 varying magnifications when using a binoviewer. Any Denk Binoviewer can be loaded into the eyepiece tube of #R2 and no additional corrector system or Power x Switch needs to be used. The Binoviewer Optical Corrector System is included and self-contained as part of the #R2 Diagonal. Changing magnifications takes seconds! Some re-focusing is required.

Is This Diagonal Suitable For All Refractors?

Because #R2 is fairly heavy and contains two 2" format Power x Switches, the Refractor mount must be robust enough to handle this very special star diagonal. The four fully multi-coated optics are 2" format and are fairly heavy themselves! The weights of all Power x Switch Star diagonals are included in the manual and focuser travel requirements are covered in the manual charts. It certainly can be used on mid-size refractors with well made mounts.
