Images are registered for the purpose of combining or comparing them, merging RGB channels, or to increase the Signal to Noise ratio.
Registration is also an essential step when searching images for transient features and new objects.
MIRA gives true sub-pixel registration that is unmatched in the quality of the result and ease of use. A process known as resampling is used to move pixels onto the new grid. MIRA makes it easy to register any number of images simply by clicking the mouse a few times. If the images contain point sources, MIRA can centroid and track the points through the images. Marking Registration Points Image registration uses MIRA's Animation capability to register an image stack.
