Possible disadvantages of Stellarium

• High System Requirements
  Stellarium can be resource-intensive, requiring a reasonably powerful computer to run smoothly. This might be a limitation for users with older or less powerful systems.
• Steep Learning Curve for Advanced Features
  While the basic features are easy to use, more advanced features and customizations can be complex, requiring users to invest time in learning how to fully utilize the software.
• Limited Mobile Functionality
  The mobile versions of Stellarium do not offer the same level of functionality and features as the desktop version, which might be disappointing for users looking for a robust mobile stargazing app.
• Occasional Bugs
  As with many open-source projects, users may encounter occasional bugs or glitches. While these are often fixed quickly, they can be a source of frustration.
• No Direct Telescope Support
  Unlike some other astronomy software, Stellarium does not offer direct support for controlling telescopes, which might be a drawback for advanced amateur astronomers looking for a comprehensive tool.
