Focusing is made easy with JMI MotoFocus – Meade Cassegrain – Round Knob. 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.

Compatible with Meade Cassegrain Telescopes (except ETX and 16") with a round cylindrical knob (see photo for comparison to hexagonal knob).
