The Jay B. Nash Stellarium is located at the Raritan Valley Community College planetarium in Somerville, New Jersey. Dramatic improvements in available materials resulted in brighter, smaller stars with improved color while consuming about one tenth of the power previously required. For this reason it is considered the 3rd generation of Stellarium technology.
It is designed to be moved onto the planetarium demonstration stage so that students can gather around it to see the local stars in real 3D. After the demonstration three light weight covers close the side and back windows for service in the lighted exhibit hall. Planetarium director Jerry Vinski and I collaborated on the design of this maximum service three foot diameter Stellarium.
