Starry Night Celestron
Starry Night Celestron is planetarium software developed by Simulation Curriculum that shows a detailed 3D representation of the night sky from any location and time. It is used by educators, amateur astronomers, and casual stargazers to identify constellations, planets, stars, and deep-sky objects, plan observations with telescopes, and understand celestial mechanics. The Celestron edition includes integration with Celestron telescopes for real-time tracking and observation planning. Users can zoom in on celestial objects, access catalogues of stars and galaxies, simulate planetary motion, and project the sky onto a dome for planetarium presentations.
AI Recommendation
1 suggestionWe could not find recent information about Starry Night Celestron's native Apple Silicon status. Based on the bundle ID structure, this appears to be a full version of the planetarium software maintained by Simulation Curriculum. If you rely on this application, contact Simulation Curriculum directly to ask whether a native Apple Silicon build is available or planned before September 2028, when Apple removes Rosetta 2 from macOS 28. An Intel-only build will stop launching entirely on that release. In the meantime, the app continues to run under Rosetta 2, but you should begin planning for a transition sooner rather than later — you have approximately 27 months until the deadline. Popular alternatives with confirmed native Apple Silicon support include Stellarium (free, open-source), SkySafari (commercial), and Celestia (free), though these may have fewer features than the full Starry Night suite.
