The Meade Cassegrain Telescope MicroFocus with Round Knob from JMI Telescopes is a push-on 2-speed manual focus mechanism that attaches to the shaft of an SCT focuser knob (or the knob itself) for precise focusing. It includes separate round knobs for coarse and fine adjustments with a numeric dial indicator for improved accuracy and repeatability. Mounting is easy and requires no drilling or tapping.
Note: Not compatible with ETX series telescopes.
