The Digistar Users Group (DUG) began in the mid 1980’s as an informal gathering of planetarians. This first gathering took place in St. Louis, Missouri (USA). At the time there were only five Digistar systems world-wide. Today there are more than 250 Digistar equipped planetaria on six continents. The current Digistar product line includes Digistar II, Digistar 3, Digistar 4 and Digistar 5 in various configurations appropriate for domes of nearly any size. The DUG annual meeting is a unique opportunity to exchange production techniques, planetarium operations concerns, Evans & Sutherland service and support, system maintenance, and ideas for new Digistar features. Other activites include particpation in IPS technology and standards efforts, ongoing member communication and peer assistance, and content sharing.
