Hi Martin,

I looked to astroalign with much interest. You mention that astroalign take ideas from astrometry.net. As I currently building some astronomy software as well, I look for a stacking algorithm like yours, but for FITS Images, which already have distortion parameters from astrometry.net In this case many of the calculation should be already done. Is that right ? Could you point me in the direction, how to find a solution with WCS Headers ?

Thanks for your help !

Michel

Hello Michael,

Thanks for your kind comment. If you have WCS with distortion there are a couple of software that I know of, that do that kind of alignment. One is reproject and the other is MontagePy. (This is a nice tutorial btw http://montage.ipac.caltech.edu/MontageNotebooks/Mosaic.html)

Hope this helps, Martin.

Martin, many thanks for the hints. Found there some entry point for trying out. Michel
