ASTROALIGN is a python module that can serve to align two astronomical images. It determines the solution by finding similar 3-point asterisms (triangles) in both images and estimating the affine transformation between them. ASTROALIGN is particularly useful when there is no WCS information available or when the images to be aligned have been taken at different wavelengths and initial “by eye” alignment is very challenging. In this 1h workshop I will impart a brief introduction into the capabilities of ASTROALIGN and how to use it.
