Spiral Galaxy M74. The bane of astroimaging in Miami, FL is demonstrated here: 25 minute subexposures x 5 still cannot show any detail in the arms of this galaxy. M74 shines at a bright magnitude 9.4 but since it presents itself to Earth face-on it has a low surface brightness and is thus fairly dim.
