Portable Planetarium Consulting
I’ve worked with domes of all diameters, from 3 to 23 meters. I’m passionate about empowering portable planetarium operators to bring high-quality astronomy education directly to schools and communities.

Tau immersive was able to help integrate several different technologies into my portable planetarium, allowing me to connect with school ages audiences at their campus on their timetable.
Without Dan’s help, I’d still be working with less user friendly technology and a lower quality audience experience. Thanks to Tau, I am able to share my passion with my audiences across the Bay Area.

“I cannot praise Dan Tell enough for his continuous support and expertise. His OpenSpace tips have been invaluable for operating my Spacedome mobile planetarium.
Whenever I encountered a programming problem, Dan was always willing to help, and his solutions were always efficient and effective. He is a true expert in his field and I highly recommend him.”
