Possible disadvantages of Stellarium

    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.

    As an open-source project, the frequency and quality of updates can be inconsistent, depending on the availability and involvement of contributors.
  • Battery Usage
    Using Sky Map extensively can drain the device's battery quickly, particularly when using augmented reality features and GPS.
  • Learning Curve
    While generally user-friendly, complete beginners might initially find it challenging to use the app effectively without some prior knowledge or guidance.
  • Data Usage
    Downloading star maps and other data for first-time use or online functionality could consume a significant amount of data, which could be a concern for users with limited data plans.
