I have been trying a bit around to platesolve an image of M31 and it did not really work in Siril so I just put it in Astrometry.net and it solved. So now I have the wcs.fits from Astrometry laying around and I would like to “just add the information”. I know it may not be that simple to add but I would certainly like an option to add the platesolved coordinates form other sources.
In next version we have worked on astrometry. But this feature is not scheduled however.
