M74, aka NGC 628, as
seen through the big eye of
the 1.23M scope at Calar
Alto Observatory in Spain.
M74 in Pisces is a face-on
spiral galaxy about 30
million lightyears distant.
Along with M81, M51, and
10% of spiral galaxies, M74
is considered one of the
"Grand Design Spirals". Its
low surface brightness
makes it a difficult target for
backyard visual
astronomers.
