This spiral galaxy in Pisces was discovered by Mechain in September 1780 and Messier observed it on October 18, 1780. At the distance of 32 million ly, it is 97,000 ly across. M74 can be spotted 1°20' NEE of h Piscium (see finder chart below). It is the fist object and the toughest one to find during Messier Marathon. On photographs or CCD images it resembles M101 in Ursa Major.
