MontagePy is a toolkit for assembling astronomical images into custom mosaics.
.
It uses algorithms that preserve the calibration and positional (astrometric)
fidelity of the input images to deliver mosaics that meet user-specified
parameters of projection, coordinates, and spatial scale. It supports all
projections and coordinate systems in use in astronomy.
.
It contains independent modules for analyzing the geometry of images on the
sky, and for creating and managing mosaics; these modules are powerful tools
in their own right and have applicability outside mosaic production, in areas
such as data validation.
