What's New

Added Android mirror, version 1.10.3

This release mostly aimed at fixing issues but also brought a few new features:

  • New projection: Equirectangular (fills the screen)
  • Improved rendering of Milky Way, Zodiacal Light and landscapes
  • Improved rendering of the Moon
  • Improved HiDPI behavior
  • Use Noto as default font
  • Added Modern (IAU), Tikuna and Seri sky cultures
  • Added Chinese and Bahai calendars (Calendars plugin)

Behind the scenes, several minor issues were fixed.


It seems the TelescopeControl plugin at least on Windows works better in the Qt5-based releases. Just install this if you are affected. We are looking for telescope users with programming skills to help us fixing this issue. Reward possible!
