An observer or telescope operator designs an observation plan to take advantage of multiple imaging systems, sharing a common telescope mount. The primary imaging system is the leader, taking images and providing coordination to the subordinate image systems running their own imaging tasks. Maestro leads the subordinate players in concert, much as the conductor of an orchestra leads the musicians with their own instruments. Unlike a symphony conductor, it also performs its piece on the primary imaging system. The lead imaging system runs MaxIm DL Pro with a Maestro server, and operates the standard complement of observatory equipment including camera, filter wheel, guider, mount, dome, etc. Each additional Maestro client – a limited version of MaxIm DL Pro – operates a single additional camera and filter wheel. Like a band leader, the Maestro server gives cues to all interested Maestro clients and checks that the slowest client is ready to move to the next part.
