This JMI Telescopes MOTOFOCUS Electric Focusing Motor is designed to easily attach to select Starlight Industries Feather Touch focusers, and is controlled by a simple easy-to-use hand controller. It installs without the need to drill and tap new holes or any other permanent modification. The MOTOFOCUS gives you impressive control of the focusing mechanism to allow you to achieve a level of precision focusing not normally possible manually, with the additional benefit of not having to touch your telescope, avoiding unwanted vibration. With variable speeds and an electronic breaking system, this device eliminates the backlash that is native to most focusers for clearer viewing. The use of the MOTOFOCUS provides the vibration-free precision focusing required for astrophotography or when using extremely high-magnification eyepieces.

    MOTOFOCUS Electric Focusing Motor for Starlight Feather Touch Focusers is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from A must-have addition to a Starlight SCT micro focuser This device is an excellent piece of kit, and utterly necessary to get the most out of a Starlight feathertouch focuser, particularly on a Celestron SCT with the Evolution one-armed mount, which gives you jiggle when you touch the focus knob. Even with the feathertouch unit's fine control, the movement makes finding focus at high magnification difficult. But with the JMI motofocus added, there's no touching the knob and therefore no movement, so it's possible to slide in and out and watch for the sweet spot. One minor cavil: the plastic sleeve that goes on the feathertouch focuser shaft in order to mount the JMI motor fits a bit too tight, but a little careful work with some fine emery-paper around a finger is enough to adapt it to go on more smoothly. That aside, the JMI unit is very well made; the plug-in control box is made of sturdy composite, and the motor has a nice wrinkle-finish metal housing full of precise metal gears put together like a Swiss watch. This is a must-have. Service from B&H to Canada is excellent, and it's especially convenient to be able to pay any Canada-imposed nuisance charges at the point of sale.
