Because of the new technical hurdles in creating 3D video content for the dome many planetariums opt to lease programs from institutions that have already gained ground in the fulldome field such as the Hayden Planetarium of New York or the Clark Planetarium in Salt Lake City, or from vendors such as Starlight Productions and Loch Ness Productions.
