with the multiplication of spacecrafts over the past year, the Celestia screen is overloaded when displaying names and orbits. It is the same problem as for asteroids and comets.
The use of the Vidiba module in Lut5 is not limited to asteroids.
on the 1st image, you can see what happens if everything is selected.
on the 2nd image, we see that it is much clearer using Vidiba and its possibility of selective display.
To do this, you must create lua tables for each desired category. Then declare this table in the Vidiba part of config.lua after the comets (which loads them at startup). In your local language, define a translation of the name of the table by what you like. Object .ssc files must include the parameter: 'Visible false'. Vidiba will pass it to 'true'.
