Optec now offers a complete focusing rotator option for owners of Takahashi's legendary Epsilon 180 Astrograph. Gemini's Low-Profile Focusing Rotator, coupled with the #19843 and #19844 adapters provides a drop-in replacement for the native E180 focuser.
The #19844 adapter allows
owners of the Takahashi Epsilon Astrograph to insert their field flattener directly into the Gemini. Proper spacing is maintained for the E180 Field Flattener with a recessed M68 thread. First screw the Field-Flattener into the #19844 adapter, then secure the FF/Adapter assembly into the Gemini drawtube. This sets the FF at the design distance from the primary mirror and maintains the 56mm back-focus available to the camera sensor.
