Hello everyone,

I would like to know how I can combine two FITS images (which are continuum maps of two sources) in python using astropy.

Hello mahya

If this is a homework question it should be posted in "Homework" section.

In any case, take a look here at http://www.astropy.org/astropy-tutorials/FITS-images.html. Knowing how to open FITS files and load data you then can do various manipulations using arrays.
