Luminos vs Orbiting Sky

Thank you for being a part of my journey with Luminos! As I strive to bring you the best in astronomical software, I want to let you know that, after 12 years of updates, this version of Luminos will be retired in 2023. But there's exciting news: I've developed Luminos Pro, an advanced version that offers even more amazing features and updates. To continue providing support and updates to my existing customers, this version will stay available in the App Store for now. I invite you to explore my latest features and designs in Luminos Pro and join me on this continuing adventure. See you in the stars! Clear skies, - John
