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 universal plug-and-play control. ASCOM is a many-to-many and language-independent architecture, supported by most astronomy devices which connect to Windows and now Linux and MacOS computers. This architecture applies to both Windows/COM and cross-platform Alpaca technologies.

Need Help with an ASCOM compatible device or application?

The following live stream videos are nearly an hour long each. If you want to learn what we're doing to keep astronomy software as an open ecosystem, we hope you'll devote the time to learning. If you're new to all of this, we suggest you watch the Non-Technical Overview first.



For more information on the ASCOM Initiative, see the About ASCOM section and the navigation menu on the left.
