Description

A friendly group for folks interested in building and/or operating a planetarium. There are a wide range of possible uses for small planetariums ranging from traditional astronomy education, to some of the new opportunities in wider science education, visualisation, art, and entertainment offered by fulldome digital projection.

Backyard enthusiasts, operators of portable planetarium businesses or permanent planetariums, equipment vendors, and content suppliers are all welcome.

If you are new to this group then be sure to check out the links on the left, in particular, the photo gallery and please contribute to the poll questions. If you have some good photos of your own small planetarium related project then please contribute to the photo gallery.
