Chimera: Observatory Automation System

Chimera is a package to control astronomical observatories aiming the creation of remote and even autonomous observatories with just a few clicks. Using Chimera you can easily control telescopes, CCD cameras, focusers and domes in a very integrated way.

Fully distributed system. You can use different machines to control each instrument and everything will looks like just one.
Very powerful autonomous mode. Give a target and exposure parameters and Chimera does the rest.
Web interface
Web interface to schedule and monitor observations (in development).
Hardware support

Support for most common off-the-shelf components. See supported devices.

Very easy to add support for new instruments (it’s Python code!).

Chimera can be used in a very integrated mode but also in standalone mode to control just one instrument.
It’s free (as in free beer) and written in a very modern language. Python!.
