Does someone have a solution for this?
I'm on Ubuntu and it's been a pain to set up kstars, multiple crashes and so on.
I downloaded the index files for plate solving, but I lost the FOV for the camera and I can't even plate solve or anything , although I have nearly all the index files downloaded.

Polar alignment says "FOV must be 10" or greater".



I know there was a default link in the index file location, but I replaced that with my local drive location.

How do I solve this? Do I have to delete Kstars and reinstall?

inf indicate that there is somewhere zero that causes that focal length is zero. try to recreate your telescope info with proper focal length and reducer/Barlow set to 1x.

you may try to delete ~/.local/share/kstars to get rid off configuration and start from scratch.

Ok there seems to be bug in kstars that if I change barlow multiplier in optical trains to anything else than 1.0 then it start outputting
org.kde.kstars.ekos.align: "Warning! The calculated field of view (inf' x inf') is out of bounds. Ensure the telescope focal length and camera pixel size are correct."

also in userdb.sqlite it save 1.2d or 0.8.2d in reducer column.

EDIT: and it was already fixed invent.kde.org/education/kstars/-/commit...76ea9e2a4994c1e00054

What I can tell must have caused it, that after installation of Kstars, I immediately set a new directory for the astrometry files and removed the default one.
Never done this before, but I just got tired on previous installations asking me to download more files for my imaging train, when I was already imaging. So I didn't want to waste time with that and tried to be ahead and be ready.
I did all my telescopes in the "scope and lenses" and tried it with different scopes and no barlow and it still gave me that error.

I guess I must not change the astrometry directory before connecting any cameras.
