Summary0002345: Comet/asteroid trajectories are hidden when object is too far outside viewport
DescriptionIf you choose to show a comet/asteroid trajectory, the whole path disappears once the object is too far off screen. For example, set the time to 1997-01-01, 00:00 UTC and display the trajectory of C/1995 Hale-Bopp, 100 steps, each 3 days, which will generate its path over the sky for 300 days after January 1, 1997. Unless you view near the comet, the path/trajectory will be hidden from view.

The same happens for asteroids, but not for planets.

The program do not show all the trajectories that start far from the current FOV for performance reason. With all the asteroid this is more than 800'000 trajectories that can potentially be plotted.

But it is right the object selected in the new 4.3 asteroid or comet filter must always be show on screen.
This is fixed and will be available in next week beta version.

A trick to make it work with the current 4.3 beta version is to search for the selected object.
In your case type hale-bopp in the quick search bar, this center the chart at the first position, then you can move everywhere along the path and it stay visible.
