Astrometric registration of images when no WCS info is available
Astroalign is a Python module that will try to align two stellar astronomical images, especially when there is no WCS information available.
It does so by finding similar 3-point asterisms (triangles) in both images and deducing the affine transformation between them.
Generic registration routines try to match feature points, using corner detection routines to make the point correspondence. These generally fail for stellar astronomical images, since stars have very little stable structure and so, in general, indistinguishable from each other. Asterism matching is more robust, and closer to the human way of matching stellar images.
