With the MicroTouch Direct Drive, the motor assembly bypasses the fine-focus mechanism and runs the focuser pinion directly, eliminating the possibility for slippage. In order to maintain the precision of the Feathertouch, the MicroTouch Direct Drive uses a high-ratio gear reduction system. This produces an im
