M74 (NGC628) is only Messier's object in the constellation of Pisces. You can find that at about 1 degree east of eta Piscium.
The galaxy has a size of 10 arc minutes and about 10th magnitude, it's a very faint spiral galaxy being face on, one of the faintest in Messier's catalogue. It's fairly difficult work to recognize the galaxy with a medium-sized telescope unless you have extremely good-conditioned night.
Long exposure photographs show two loosely-wound spirals out from a tiny bright nucleus.
The galaxy is 31 million light years away.
