Sleeping Bear Dunes National Lakeshore is excited to share that the park’s Interpretation and Education division now has an inflatable planetarium dome to enable immersive experiences related to the night sky, the Great Lakes ecosystem, and more! The dome was recently purchased as part of a grant from the National Park Foundation. A vertically mounted laser projector with a fisheye lens enables detailed 360-degree images and video to be projected on the inside, while a fan provides constant air pressure to keep the dome inflated.
