I could be missing something, but it seems that all you need is to add
the flux of every pixel containing the object. Since there is no
atmosphere in the way, there is no sky flux being added together. They
are usually observed nicely isolated, with nothing around them to
contaminate their flux. Then if you want absolute magnitudes, you
could just take the ratios of those fluxes to those of some standard
star observed by the same instrument (Cassini does occasionally look
at stars, for photometric and pointing calibration).
