FocuserOne – astrojolo shop

If you look just for the focuser controller to your telescope, then you are in the right place. FocuserOne is simple to use yet powerful device that can control almost any type of focusing stepper motor. It is equipped with dedicated panel software, ASCOM and INDI driver, buttons to control the focus manually, and astro-friendly high contrast OLED display.

FocuserOne device supports unipolar stepper motors (like Robofocus or Moonlite), and bipolar as well. In terms of the motor resolution, FocuserOne supports full-step mode, half step mode, and two microstepping modes – 1/8 and 1/32 step.

Temperature compensation is possible with an additional temperature and humidity sensor. FocuserOne supports linear compensation. A compensation calculator is available, so determining the temperature compensation coefficient for the setup is pretty straightforward.

Another useful functionality of FocuserOne panel software is charting. Changes in focuser position, ambient temperature, and humidity (with optional sensor) can be presented in a graphical way, but also can be written down to the log file for future processing.
