Redesigns DRO Hand Unit
has redesigned its Digital Readout (DRO) Hand Unit to optimize functionality
with its new Event Horizon Focusers (EV), as well as with its long-standing line
of Next Generation Focusers (NGF) and all other JMI MOTOFOCUS equipped focusers.
The new DRO Hand Unit features a red LED four-digit
numeric digital position display and two directional focusing buttons, plus a
variable speed control. The DRO Hand Unit also features a dimmer control
and a control for zeroing the display. Shown is the JMI DRO Hand Unit and
its popular EV-2cM focuser.
One end of the included cable attaches to the hand unit
and the other to the encoder assembly of the controlled focuser for
ultra-precise focus control The DRO Hand Unit is connected to the motor
and encoder assemblies of the JMI EV-2cM focuser using a standard flat phone
cable and connectors.
The new DRO Hand Unit provides a ready, stand-alone
means of repeating focus to a precision that visual and analog methods simply
cannot match. The new JMI DRO Hand Unit is priced at $148US.
