Rigel Systems nFocus Control Box

The nFOCUS controller fits in the palm of your hand and provides two directions at two speeds with only two buttons using advanced logic control and 12V regulated output. From a quick coarse adjustment for finding focus to an ultra-fine adjustment for astrophotography, anything is possible.

Press the second button while holding down the first button and the nFOCUS digital logic control switches to the high speed drive, so you can focus quickly.

Simply adjust the speed with the first knob, from extremely small steps to a fast setting. Use the second knob to adjust the distance between the steps. This allows you to focus with the extreme precision required for astrophotography.

nFOCUS avoids the problems with focus motor controllers that adjust the voltage to adjust the speed and therefore do not have the ability to spin the motor at low speed. The nFOCUS hits the motor with a full 12-volt pulse of short duration to overcome friction in low-speed operation, which provides a huge amount of power. It's amazing to watch nFOCUS work, to see the focus change step by step until it's perfect. No more going through, going back and then going through again.

Uses 3 AA batteries (optional) for longer life.
