INDI Rainbow Astro RSF driver is included with libindi >= 1.8.8 Under Ubuntu, you can install the driver via:
sudo add-apt-repository ppa:mutlaqja/ppa
sudo apt-get update
sudo apt-get install indi-bin
Rainbow Astro RSF is a secondary mirror focuser with a stepper motor. It includes a physical remote controller that can be used without a computer.
Please note the range for the RSF focuser is -8000 to +8000 with zero being the home position. However, in INDI the range is 0 (corresponding to -8000) to 16000 (corresponding to +8000) with 8000 being the zero home position. You do not really need to take any action, this is just for your information.
The Options tab contains settings for all drivers that include polling (frequency of updates), logging, and debugging. Contains the option for simulation to run the driver without using the physical device.
You may set pre-defined presets for common focuser positions in the Presets tab.
There are no known bugs for this driver. If you found a bug, please report it at INDI's Issue Tracking System at Github.
