About
AstroPlanner is a comprehensive astronomy software application developed by iLanga, Inc., designed for both Macintosh and Windows computers. It serves as an all-in-one solution for astronomical observation planning, sky visualization, session logging, and hardware control. At its core, AstroPlanner helps astronomers plan their observation sessions by leveraging a rich set of astronomical catalogues, allowing users to identify, schedule, and track celestial objects of interest. The built-in visualization tools help users understand the positioning of objects in the sky relative to their location and time. A standout feature is the software's ability to directly interface with computerized go-to telescope mounts and digital setting circle (DSC) controllers, enabling users to automate pointing and tracking from within the app itself. This makes it particularly valuable for backyard astronomers who want a seamless workflow from planning to observation. AstroPlanner also provides robust session logging capabilities, letting users record detailed notes about each observation for future reference or community sharing. The software is distributed as shareware, meaning anyone can download and use the fully functional application at no initial cost. A license purchase is required for continued use. It supports macOS 10.14 or later and Windows 8.1 or later, with an unsupported legacy version available for older operating systems. Whether you're a casual stargazer planning weekend sessions or a dedicated amateur astronomer managing an observatory setup, AstroPlanner provides the tools to enhance every aspect of your observing workflow.
