Focusing is made easy with the JMI Motofocus MFGSO4 for the Meade Lightbridge 16" telescope. This Motofocus requires no drilling or tapping for mounting. It is a user friendly hand control with an electric focus motor that attaches to the shaft of a focuser knob (or the knob itself). It is battery operated and comes with the 9-volt battery. The Motofocus offers precise, vibration-free focusing without the need to touch the telescope. This unit features variable speed for course and fine adjustments. Optional Digital Read Out (DRO), or Digital Focus Counter (DFC), can be added to improve focusing accuracy and repeatability.
