Abstract. We present far infrared (FIR) images of the two nearby galaxies M51 and M101 at 60, 100, and at 175mum. These images resolve the spiral arms of the galaxies and a number of giant HII regions embedded therein.

Key words: individual galaxies: M51, M101 - star formation - dust

* ISO is an ESA project with instruments funded by ESA Member States (especially the PI countries: France, Germany, the Netherlands and the United Kingdom) and with the participation of ISAS and NASA.
