Baffled calotte dome observation and/or communications system

Baffled Calotte dome observation and/or communications systems are disclosed. For instance, a visible or infrared telescope and associated sensor systems, a laser, etc., may be enclosed in a Calotte dome with a baffle mounted on the opening and a window and/or filter mounted on top of the baffle. The Calotte dome steers the baffle in both elevation and azimuth, enabling the system to point and track objects moving on arbitrary trajectories.
