The Hutech binoviewer (#HB-300) features quality German optics and mechanical components
for relaxed visual observing with both eyes, while still using a single objective assembly.
Interocular distance is adjustable, and the eyepieces may be individually focused for
maximum comfort using the two installed Borg eyepiece focusers.

When using the standard (straight-through) HB-300 or with the optional HB-301 diagonal, a
standard Borg 77Ach/ED or 100Ach/101ED system may be used by removing the main tube
helical focuser.

To use a standard diagonal with the HB-300 binoviewer, the HB-302 barlow must be added, or
a Borg #7129 short tube must be substituted for the standard OTA tube.

HB-300 technical specifications:
Light path diameter: 22mm
Interocular adjustment: 55 - 75mm
Back focus requirement: 120mm
