Jims Mobile, Inc. (JMI) - Digital Focus Counter for Meade SCTs non-GPS

What is a Digital Focus Counter?

The Digital Focus Counter is a low-cost mechanical alternative to the electronic DRO. The
three-digit counter display allows 10 turns of the shaft before returning to zero. If you want
focusing repeatability with an NGF focuser, SCT (Schmidt-Cassegrain Telescope) manual focus or
MOTOFOCUS, this unit will do the job. It is available for all NGF focusers (both manual and
motorized versions), as a manual unit which replaces the focus knob on 8″ or larger SCTs
(not recommended for CCD imaging due to space limitations and problems with image shift) and as a
piggy-back option for most MOTOFOCUS units. (The piggy-back option is available only at the time
of purchase of a new MOTOFOCUS unit and cannot be added later.).
