Welcome on the free astronomy wiki

Free as in free software (as in free speech), moreover it's free of charges (as in free beer) and well documented to enable people contributing to it.

Free software for astronomy is discussed and documented, whether they are related to:

A Hardware Compatibility List for GNU/Linux systems is available.

Many open projects have become available in the past years with the spreading of affordable microcontrollers and systems on chips like Arduino and Raspberry Pi. The alternative hardware page also tries to list them.

Note that the pages listed above are quite old now.

Free-Astro also hosts some projects: Siril, an astronomical image processing software and MCMTII, drivers for the open telescope motorization, and many others available on gitlab.
