Focusing is made easy with JMI MotoFocus - Orion Crayford Single-Speed Focuser. MotoFocus is a battery operated hand control with an electric focus motor that attaches to the shaft of a focuser knob (or the knob itself) for precise, vibration-free focusing at high power without the need to touch the telescope.
MotoFocus is great for visual and photographic use and features variable speed for coarse and fine adjustments. Precise positioning is accomplished through electronic braking. Mounting is easy and requires no drilling or tapping.
The Orion 80mm and 100mm ED Apochromatic Refractors use a Crayford focuser. Our MotoFocus unit designed for the Orion Crayford focuser, includes a mounting bracket, miniature motor, two gears, hand unit and power cord. The motor can be easily disengaged for manual focusing. This model will not work on the Dual-Speed version, see item #MFOPRO for Dual-Speed MotoFocus.
