I don't know the details of FITS format, but I imagine it would be something like this: - read enough of the FITS header to figure out where the image data is in the file - seek to the start of the sub-image and read the image data - construct a new header for the sub-image - write the new header and data to a new file This will require some understanding of FITS format, or a library that supports the operations you need. You might find code in PyFITS that will help.
