We all greatly value the presence of live presenters in visitor experiences. Electronic and internet Distance Learning Systems have extended the reach of the modern planetarium presenter far beyond the containment of the physical walls. At BT we sometimes refer to this as the modern "planetarium without walls".
AstroFX Universal DLS systems work with and between any new or existing systems. This means you can have guest presenters from anywhere in the world conduct talks in your dome and you can stream your presentations in real time or prerecorded to other sites, schools, and even homes with home schooling.
