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:
 * Telescope and other device control, autoguiding, autofocus, filter wheel commands, and so on.
 * Cartography, all kinds of sky maps, particularly including slewing (GoTo).
 * Image processing.

A Hardware Compatibility List for GNU/Linux systems is updated regularly.

Free astronomy also hosts two projects: MCMTII, drivers for an open telescope motorization, and Siril, an astronomical image processing software.
