Description
🎯 Dedicated Telescope Focuser Control
FocuserOne v3 is a dedicated stepper motor controller for telescope focusing. Whether you focus manually during visual observations or use automated focusing in your imaging software, FocuserOne provides convenient control and settings tailored to your focuser mechanics.
The third generation introduces STM32-based electronics and a TMC2209 motor driver, together with support for the unified AstroLink 4 Panel and ASCOM 7 software.
⚙️ Configure It for Your Focuser
Choose full-step, 1/8 or 1/32 microstepping and adjust motor speed, direction and maximum travel. Separate running and holding current settings let you tune the motor for movement and for maintaining focus at rest.
Built-in buttons provide manual control, while persistent position memory restores the stored focuser position when the controller starts.
🌡️ Follow Temperature Changes
Connect the optional temperature and humidity sensor to enable temperature compensation. FocuserOne calculates corrections using your telescope’s compensation coefficient, with automatic and manually triggered modes available.
The compensation calculator in AstroLink 4 Panel helps you determine the coefficient for your setup.
🖥️ Integrated with AstroLink Software
Use AstroLink 4 Panel to move the focuser, adjust settings, view charts and record telemetry. ThingsBoard integration also lets you publish telemetry for remote viewing and dashboards.
The AstroLink ASCOM driver connects FocuserOne v3 to ASCOM-compatible focusing and imaging applications.
