Diagonal #R1 For Refractors Allows any Denkmeier Binoviewer to be loaded into the eyepiece receptacle for 3 magnifications with a single pair of eyepieces. The Special 2" Low Power S Cell included with this diagonal must be threaded into the Power x Switch Diagonal housing or Diagonal Nosepiece on telescope-side for focus to be reached.
Diagonal #R1 Shown With 2" Low Power S Cell
Our Dovetail Connector is included and this allows any Denk Binoviewer to be quickly connected directly to the star diagonal housing eliminating the eyepiece holder. No tools are required and this exchange can be done in seconds. Remember that all Power x Switch Diagonals can be used like any regular 2" star diagonal as well. While multiplication, normal and also a reduction is possible with single eyepieces, #R1 is primarily designed for the purpose of allowing focus at three magnifications with a binoviewer while using one pair of eyepieces. The Dovetail Connector changes focus positions and primarily produces more back focus in the low power #R1 With Low Power S Cell mode (less in-travel required when it is used). Note that #R1 always includes a special Shorty Diaognal Tube which operates with the Low Power S Cell..
