Welcome to the ASCOM Initiative

This is the home of the ASCOM Initiative, a loosely-knit group of astronomy software developers and astronomy device manufacturers devoted to vendor-independent plug-and-play control. ASCOM is a many-to-many and language-independent architecture, supported by most astronomy devices which connect to Windows (and soon Linux and MacOS) computers. The diagram below shows how ASCOM differs from traditional astronomy instrument control architectures.
