About

The Charleston Planetarium currently features an inflatable dome, spanning 23 feet in diameter and accommodating 40 chairs. Constructed with innovative materials and next-generation technology, the inflatable dome offers an uninterrupted hemispherical projection surface. The zipper virtually disappears under projection, and our exclusive Nolux^™ fabric darkens black areas and helps hide wrinkles. Seating for the dome includes 40 padded, movable, non-reclining chairs. Entrance through the zipper door requires visitors to step into the dome. We can lift the bottom of the dome up to accommodate those with limited mobility.

We would like to inform our guests that our current seating, which has been generously donated, does not include headrests. While we are truly grateful for these contributions that allow us to open our doors to the public, we understand that this may affect the comfort of those with back or neck sensitivities. If you experience discomfort due to the lack of headrests, please take this into consideration when purchasing tickets. Your well-being and enjoyment remain a top priority for us, and we are actively exploring options to enhance seating accommodations in the future. We sincerely appreciate your patience, understanding, and continued support as we work toward making our planetarium as comfortable and accessible as possible for all visitors.

Our projector uses a 4k UHD projector plus our own innovative proprietary fisheye lens to project high-contrast imagery over a full dome with no blind spots or cut-outs. It allows for a full immersion-level experience. The projector has a projected resolution of 3.66 megapixels, a pixel diameter of 2160, 175° angel of projection, a brightness of 4,000 lumens, an a contrast ratio of Up to 500,000:1.

We have two couches and two giant bean bag chairs for our visitors while waiting for their show to start. Every show is on the hour. We ask that you please arrive within 5 minutes of the show’s start time.  There is no admittance 5 minutes after the show’s start time.

We are currently in the soft-opening phase of our planetarium, a period dedicated to refining and enhancing the visitor experience. As we work to develop this unique and educational attraction, we greatly appreciate your patience and support. Your feedback is invaluable in helping us identify areas for improvement and ensure that we create an engaging, informative, and immersive experience for all guests. We encourage you to share your thoughts, suggestions, and observations with us, as your input will play a crucial role in shaping the future of this planetarium. Our goal is to build a space that fosters curiosity, learning, and a deep appreciation for the wonders of the universe. Thank you for being a part of this exciting journey—we look forward to growing and improving together!
