INDI Library v2.0.6 is Released (02 Feb 2024)

Bi-monthly release with minor bug fixes and improvements

[SOLVED] Alignment fail

Replied by Jasem Mutlaq on topic Alignment fail

I was able to solve your image using solve-field. I think the problem is that it was using the solver arguments you see in the solver options and those might include current mount RA/DEC which would make it fail. I'm going to make it inspect the image FITS header upon using Load&Slew and build the argument list accordingly. Hopefully by tomorrow I can make those changes.

Ok I just committed the changes. It took 1.5 minutes to solve your image. I think it would be a lot faster if we knew the field of view, and this is why I added FOCALLEN keyword to the FITS header in INDI::CCD so that the field of view can be calculated. So now any future images you take will have the telescope focal length in it and this will make Load&Slew quite fast.

hello,

Thank's for your great job.

But for the moment, after updating Kstars, solving fail again.

options are next :
--no-verify --no-plots --no-fits2fits --resort --downsample 2 -O -L 33.6527 -H 46.4939 -u aw

I am wiring my observatory PC to make some test ...

hello,

Sorry, but I always have some trouble with plate solving. On my observatory computer, I perform an all new installation of Kubuntu 15.10, with kstars-bleeding and lots of index for astrometry.

But when I try to sync my mount by astrometry. I can see this on the logs
2015-10-31T20:48:16 Solver failed. Try again.

After looking at a lot of post about plate solving, I take a look at the version of Astrometry.net. I install it by the ppa. And when a make a apt update all is up to date, but when I make a dpkg -l astrometry.net I got this
Souhait=inconnU/Installé/suppRimé/Purgé/H=à garder

I am surprise by the version ... is it normal, I am not really award with linux, and I don't know if I did something wrong ...

I hope make this working a day.

Yeah it is old, did you add the astrometry PPA?
sudo apt-add-repository ppa:mutlaqja/astrometry.net
sudo apt-get update && sudo apt-get install astrometry.net

Please post a link to your FITS image as well.

Yes, that what I look. For the ppa, when I saw this old version, I add ( or re-add) the PPA, make a apt update, try a apt install astrometry.net, but it's allready the last version install.

I am on my Raspberry PI at the moment,
I just add your ppa for astrometry
I make a apt update
Try to install astrometry.net
<code>gaetan@RasPiAstro1:~$ sudo apt install astrometry.net
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances
Lecture des informations d'état... Fait
astrometry.net est déjà la plus récente version disponible.

but take a look at this
<code>gaetan@RasPiAstro1:~$ dpkg -l astrometry.net

hello,

There is something that I don't understand. On my desktop computer, I run with kubuntu 15.10 and the astrometry.net seams to be the good version. But with my observatory computer and my raspberry I run Ubuntu Mate 15.10 and the version of astrometry.net is an old one ? Can it come from Ubuntu Mate ?

I just ran the solver against your image and took a few seconds to solve. Regarding the older version on armhf, the astrometry.net build on armhf has been failing for quite a while. Will try to contact the author to see if he can check the problem.

thank's for helping me.

For the raspberry, it was an second example, because I find the same case that on my observatory computer.
To make a test, a put my desktop computer in my observatory. This computer got astrometry.net 0.52 ... but when I make a Capture and Solve, the solver failed.
The same image (from /temp/fits...) with the same command line from Ekos logs, in a terminal, it works ??? when Ekos try to solve my image, Ekos failed, but when a terminal try, it works ...

Does regionnal parameters are important, "," and "." or "," and ";" ... all my computer are install in french ? Can it be important ?

Thank's again

I'll put logs of my last session soon.
