Changes Between V6.1A and V6.1G of "The Earth Centered Universe Pro"

Sky Chart/Print Features

• The split chart now has separate settings for horizontal and vertical flips.
• The number of objects that can be plotted on-screen has been increased to 30,000.

Databases

• The General Catalog of Variable Stars database has been updated to the current (V5.1) version, and it now contains 54,919 stars.
• The number of comet/asteroid orbits that can be active at any given time has been increased to 25,000.
• Added download of and full support for the IAU Minor Planet Center's asteroid orbit database.
• Added support for download of the MPCs bright minor planets at opposition list.
• The master orbit file is now called 'masterorbit.orb'.

Searching

• You can now search for a specific equatorial position as an RA in hours and minutes OR hours and minutes and seconds and a Dec in degrees and minutes OR degrees and minutes and seconds.

Automation Interface

• The Search method now returns the found object's primary object name.
• Added the ClearOrbits, LoadOrbits, SaveOrbits methods.

Miscellaneous

• Updated the URL for General Catalog of Variable Stars web searches.
• Orbits now accept eccentricities up to 5 (for the new class of interstellar asteroids).
• Better error handling in the loading of orbit files.
• The angular separation calculation uses a more accurate "haversine" algorithm.
• Telescope serial interface routines now use an external COM Port Driver (developed by Nova Astronomics).
• The default application style is 'Onyx Blue' and when changing styles they are previewed in the 'Colors and Styles..." dialog box.

Bug Fixes

• Some problems with dialog box sizing on some computers has been resolved.
  Broader ASCOM exception handling was added.
• Some mathematical overflows and other problems were fixed there were caused by the new "interstellar" asteroids and orbits with hyberbolic orbits.
• Add better error handling for parallax calculations.
• Improved program shutdown if started by the automation interface.
• Fix bug where sky was not redrawn on alignment stars during encoder interface alignments.
• Fix bug where telescope interface was sometimes causing an error when disabling it.
• Fix bug where alignment star names were not shown during encoder interface alignments.
