The MOTOFOCUS for Explore Scientific AR-127 Telescopes from JMI Telescopes 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 without the need to touch the telescope. It is suitable for visual and photographic use and features variable speed for coarse and fine adjustments. Precise positioning is achieved through electronic braking. Mounting is easy and requires no drilling or tapping. The optional Digital Read-Out (DRO) or Digital Focus Counter (DFC) can be added to the MOTOFOCUS for improved focusing accuracy and repeatability.
