I am already aware of issues with comets position and there are several bug reports on that. I guess asteroids are a similar problem. Unfortunately, we don't have resources to work on this problem and I'm already busy with all the things in INDI & Ekos as is. If someone can dig in the code to find the issue, that would be great, it's an open source project after all.

What is the correct source for kstars? Is it git://anongit.kde.org/kstars.git or github.com/KDE/kstars ? Can I just fork github version to work on the code?

I compile from source with "git clone git://anongit.kde.org/kstars.git"

If you change any code and want any beta-tester send me message ..thx.

KStars github code is a mirror. Here is the primary repo: cgit.kde.org/kstars.git/

git clone git://anongit.kde.org/kstars.git

To submit patches, either send me directly to me, or via KDE Phabricator ( phabricator.kde.org/ )

I change value in ~/.local/share/kstars/asteroids.dat ..no changed any!! ( sure read from this? )
Now change value direct in source kstars and recompile.
